Full Metal Gantry

[severe glade]

currently printing the last part for the fan shroud

still need to figure out endstops

[heady solar]

very nice! 🔥

[sudden kite]

do the 6mm front idler towers use m3x30 or m3x20 stand offs, the step file shows 30 but the instructions say 20? i already bought 30 but im starting to have doubts.

[shut pewter]

Measure CAD

They are just labeled wrong in CAD

[sudden kite]

ah gotcha

[late axle]

Can't you use sensorless?

[severe glade]

Probably?
I havent looked into it
Is it hard to setup?

[severe glade]

Have u done it?

[late axle]

I did by accident once

Copied someone elses config lol

[severe glade]

lol

i guess ill look into it a bit

[verbal burrow]

not hard to set up with kalico

I'm only using Sensorless on my small printer though, the merc will have endstops

[shut pewter]

Endstops are easier to setup and not reliable

I do have a few printers with sensorless now, but that's mainly in printers designed without endstops. My red Merc is sensorless due to takeoff not having a x endstop.

[verbal burrow]

Yeah, id add an endstop if possible, in general

[broken venture]

I went hard pcb

[severe glade]

what length standoff do you have between toolhead and fan duct?

[late axle]

Your duck almost look resin printed.

[lavish sinew]

it is resin printed

[ocean yoke]

This is why

[sudden kite]

i put together my gantry without any thread locker, was that a bad move? didn't have any on hand and got too excited to not put it together but im wondering if i should just order some and apply it before i finish assembling the whole printer

[uneven solar]

these switches work pretty bad for me for some reason

[swift rapids]

I'm using a similar switch, just have to watch my homing speed or it'll jam triggered.

[uneven solar]

what sort of speeds are we talking about here

i think i use 100-150

[indigo bough]

I had 2 questions about this. Does this give some extra X clearance, like the Mod Max, or is it the same as the normal Mercury one? The other question was in regards to getting in manufactured in the US. I did a quote with SendCutSend, but one of the parts was being quoted at $400-$500. Xometry seemed much more reasonable, but still more than the prices I've seen mentioned in the thread here. Any advice on this?

[heady solar]

you have to select certain settings, make sure its the correct metal, etc.

[shut pewter]

Did you upload the files in inches?

this does not gain any travel

[indigo bough]

I just dragged the files onto the webpage, no idea what measurments I was using. I'll try it again. I did try selecting different grades of aluminum, they were all in the $400-500 range.

[shut pewter]

yeah probably was in inches which is default

need to set it to metric, total price should be around $90

[indigo bough]

Ok thanks, I'll try again and see.

[indigo bough]

Yeah that was it, for some reason it was using inches, even though the DXF variable is set to millimeters. I found out if you add multiple files at once, it doesn't give you the options to change the measurement, so I just have to add each file individually, then you will be prompted for the units.

[shut pewter]

DXF is a unitless file format, which is dumb. But it is what it is.

you can change the defalut units for your account, that it imports in

[opal spindle]

as I'm waiting for parts and to become available and ship and have been looking into getting a hotend working with my SO3 and I was wondering: has anyone looked into making an all metal toolhead?

[heady solar]

theres no point as your hotend would be the limiting factor in that case

it might not even be worth fmg with SO3 😬

[shut pewter]

pretty sure they were asking about one for the mercury

vz bot has one that works for us, vzcnc for mercury

[opal spindle]

Sorry I'm confused: Limiting in what regard?

[heady solar]

speed for most. speed is the reason most get fmg
vz zerog cnc works for merc. idk abt support regarding SO3 tho

[opal spindle]

The SO3 has a flow rate of of 30-40 mm3 with a cht at 6.5+kg extrusion force so I'm not too worried about speed

And I was fully prepared to design my own tool head and have SCS manufacturer it

[opal spindle]

Thanks for the rec,
looks like the top plate needs to be shortened and a front plate with holes for the so3 needs to be made and that should work!
My only consideration is do I want to make a toolboard mount to shorten the overall width of the package

[heady solar]

the meltzone is tiny... have you actually tried this with a 0.4 nozzle?

[opal spindle]

honestly no but i can get back to you once the whole thing's put together

in my current system the motion system falls apart far before I can even dream of needing anywhere near those flowrates

[vague raptor]

This is a stupid question - I know its related to the toolhead mounting but what is the difference in the CAD files for top vs front mount?

[shut pewter]

Simple as your toolhead having a top mounted rail or front mounted

Voron sb is front mounted

[vague raptor]

Oh bruh, thanks Turtle!

[stable iris]

Is there some saved cart or link to all the FMG 9mm parts needed on SendCutSend or do I need to load the DXFs and spec them manually on their site?

[shut pewter]

No saved carts

[stable iris]

Copy, thx.

[limpid grove]

Planning on upgrading to the full metal gantry soon, but I have the original run of the rear metal stepper towers, are those able to be reused? And if so, any considerations needed in what I order?

[shut pewter]

just need to replace the printed inserts

[opal spindle]

how important with the high tension setup is it to have the belts come out at a perfect 90 degrees to the y rails?

I'm working through making making a custom SCS-able all metal toolhead for my upcoming all metal gantry build and in my speed to get the extruder as close to the rail as possible neglected to consider where the belts were in relation to the front plate
note: this is still very much a work in progress

[stuck belfry]

For compact and light you might want to have the tool opposite side of the belts and maybe put anything but cooling above the rail. I dunno if it's feasible, but that would compact masses

[slow pelican]

@shut pewter a fun company made a kit for this mod :3

using your picture aswell

[shut pewter]

I know

[orchid marsh]

Bruh couldn’t even take they own photos

[heady solar]

if i could express my anger at this, i would be banned

[wintry marsh]

The dumb thing is they just made the bottom part a 6mm plate so the pins won't work properly either....

Why is funssor so dense.

[broken venture]

If they copied the wrong plate, then the dual shear bearings wont work either XD

[heady solar]

how do you know>

whos bought it?

[wintry marsh]

Nobody is just looked at the listing on ali lol

[heady solar]

wow that is so shit

[broken venture]

So that means the pictures are wrong too...... so they used incorrect and stolen images XD

[pallid quest]

They are using 5mm pin with internal thread, like a double t pin without the middle flange.

[tender token]

dangggg...

lets leave some crappy reviews there

[heady solar]

Ive thought about leaving warning reviews on all zerog clones but dont know if that would be morally ok

[pallid quest]

Best to just leave the warnings here, if we had a message that people saw when the first came here that explains the situation and that there is no support here.

[heady solar]

Ive suggested that to dutch, hes not in support of it tbh

[pallid quest]

Then we just let people know we can’t help them if they have issues and ask with those parts.

[spark gate]

Durch is against manhunts
Which is good imo
So yeah
Warn the people
But don't overdo it

[heady solar]

yeah. I see his moral pov but I feel like just posting: these companies are not supported because they make illegal clones will help a lot of people

[spark gate]

It is already in the announcements

[heady solar]

ik, but its not specific, and is old. No one will notice it

[spark gate]

I have a better idea
Instead of: this bad
How about:
These things are official, everything else isn't
In the rules
@torpid summit

[heady solar]

list of vendors?

[heady solar]

add "everything else isn't, clones may have bad results"

[pallid quest]

Anything unofficial may have unwanted results

[torpid summit]

Well there will be an official blacklist soon

[spark gate]

Any vendor not on that list may yield undesirable results

[pallid quest]

Yea, wording is important in my opinion. Don’t want the community to come off as aggressive. Most people that buy it don’t understand so there is no point going off at someone that gets them and then has a bad experience, just makes them not want to be in the community.

[heady solar]

really? where will it be posted

[spark gate]

Yeah
It's important not to antagonize people

[unreal lake]

I always like that Dutch and Turtle try to put us, the community, 1st and as such by not alienating new people who have already been burned by a bad purchase.

[heady solar]

I really like that too. You can tell just from talking to him for like 10m that hes very morally aligned, he cares about all of us, and wants the best for the people he interacts with

[primal halo]

I'm way late to this but I am also working on the exact same thing. As far as I know it is crucial to keep the belt plane parallel to the gantry to avoid what I would call "cosine error" in the belt path throughout the X travel. I am working on putting the SO3 toolboard on the back face and routing CPAP cooling around the back. I also have a draft one piece billet bracket and drawing to go along with it. Hopefully won't cost an arm and a leg put I guess printing it is always an option (maybe Nylon or PPS idk). Did you get anywhere on this concept?

[heady solar]

I wouldnt use the eva 2.4 clips

[primal halo]

Yea somebody did mention that to me a couple months ago, haven't got around to updating to the better design.

[opal spindle]

I restricted myself to sheet metal components and I'm not nearly as far along as you are but I have some screenshots in the toolheads channel

[heady solar]

you can make belt clips, ducts, etc. out of plastic tbh

[opal spindle]

my plan is to have just the fan ducts in plastic if I can help it

[heady solar]

SLM printed would cost a lot

[primal halo]

Yup I see that now. Looks pretty good. I'm a big fan of shiny metal things but if billet is too expensive I might steal your idea.

[shut pewter]

SLM is cheap if you design it for SLM

[heady solar]

if youre going eva style, you shoulld maybe adapt eva 2.4 hemera mount, or make a special front for e34m1

[opal spindle]

if it ends up working out I think I'll set up a github page

[shut pewter]

That looks very chunky as it is though

[opal spindle]

mine?

[shut pewter]

Lonzo's

[opal spindle]

ah

[shut pewter]

I also do not personally see the point of metal toolheads for either of those extruder setups, but thats just me

I think those do not belong on corexy printers

[heady solar]

yeah the shape seems to be more targetted towards bed slingers

I think if the hotend was goliath length, it would be worth it

[opal spindle]

btw since you have more experience getting laser cut parts made: would you be down to glance at my design at some point to see where I can afford to shed some weight, once I get to that point?

[heady solar]

make sure you do forces analysis too

[shut pewter]

I just make things look good and send it

[heady solar]

really?

[opal spindle]

I wasn't able to find a standard toolhead that would work and since my printer is down laser cup parts looked like the easy option

[shut pewter]

I dont even do FEA on stuff, other than cantilever z stuff because of the $$$ it takes to buy those parts

zero fea on the metal gantry, I did 3d print the first stepper mount design to verify it would at least work in concept.

xjoints were just make it look good, and leave enough to look good

[heady solar]

I wonder how nice cf xy joints would do

[opal spindle]

not sure how I can do that with my free tier of fusion 360

[shut pewter]

I only just started to figure out FEA for cantilever, after I built it to see if it was feasable on the 5 plus 🤣

[heady solar]

use ondsel or freecad

[shut pewter]

unless you know what you are doing with FEA, the results do not mean anything

I am able to run tests for what I built, and what I plan to build next. Using what works as a baseline

[heady solar]

I want to learn more about it. atm, I understand CFD decently, but will have to learn FEA for my slinger bed

[opal spindle]

didn't onset get shut down in october of last year?

[heady solar]

wait yeah youre right, Im thinking of some other software but forgot the nam,e

Simscale! thats what it was. I dont know how I got ondsel

[shut pewter]

my latest z sim with gravity and 1kg on the bed

using the rails in the sim, actually improved the results.

[primal halo]

Yea I did consider doing something modular to link into another project but I figured that the irregular form factor of the Orbiter V3 would make it less relevant and awkward to adapt to a system meant for the V2.5. I know a lot of people wouldn't want to go this route because they won't see the cost/benefit. Personally I think that it makes sense to spend on a nice tool head since it is arguably the most important part of the motion system and is actually subjected to inertial forces regularly. Considering we are already spending extra on the metal gantry components I think a metal toolhead is a logical next step. I deal with plastics quite a lot in my day job and the major concern isn't really its outright strength but more its resistance to fatigue, creep, vibration etc. in practical use cases. FEA for additive is also tricky because the material you are trying to simulate is non-isotropic and I would rather deal with a known quantity. FWIW solidworks says my bracket is around 60 grams for 6061.

[heady solar]

If you want better cost to benefit, I wouldnt do so3

[primal halo]

Yea the goal for my build is kind of the opposite of cost/benefit because I am going for outright material capability. I'm even going for the Revo version which makes that even worse, mainly because I want to go for exotic filament at high temperatures. I just wouldn't' trust plain ABS to hold up in those conditions long term.

[heady solar]

then you should get goliath

I def want to make my build high end at some point and handle 100c chamber, and Im likely going to go goliath for that reason

all metal gantry/toolhead

high temp water cooled motors, etc.

[primal halo]

I was under the impression that it was targeted more for extreme speed, even though it is packing an enormous heater. There's a good thermofluid analysis somewhere on the oribiter site that shows why you really don't need big heating power for high temperatures. The stock E5 could probably get well above 300 under it's own power if it wouldn't destroy itself in the process. I guess I'll have to research it a bit. The thing that worries me just looking at it for air cooling is the size of the heatsink. Also seems on par with SO3 Revo $wise in Canada at least.

Edit: https://www.orbiterprojects.com/so3_story/

[heady solar]

goliath is also a popular choice for hight temp printing (without the sock ofc)|
my biggest problem with the so3 is the form factor, whch makes it cumbersome to mount on corexy

[primal halo]

I've seen a lot of people make that same comment but I don't really see it that way. I know the meta has moved to top mount extruder. But as is, it's quite compact and could even mount in a similar fashion if used with a front mount rail. I think the only hurdle practically speaking is the fact that there isn't much support for it. I don't see the design and manufacturing as a big problem but who knows, maybe my arrogance will come back and bite me lol.

[heady solar]

If you want to use so3, you shouldnt use top rail
top rail also isnt meta, and theres basically no such thing as meta in 3d printing as most of us are crazy engineers trying new things all over

[primal halo]

Yea maybe meta is the wrong word, I do see it a lot though (VZbot, ratright, EVA 2.4, Proforge). I agree with front mount being better but I want to use the front and back of the carriage block to mount things and I think top mount lends itself that with CoG in mind

[heady solar]

archetype, tajkeoff, a4t, etc. use front mount

[primal halo]

One thing I noticed as well is the front mount rail systems, like the stealth burner for example, have the extruder kind of sitting above the carriage block. The only drawback being a longer filament path from extruder to nozzle and I think you need to put a PTFE tube as your filament path in some designs. One day we'll converge on the ultimate no-compromises package 🙂

[heady solar]

stealthburner is an abominable design imo

[primal halo]

damn don't hold back 😂

[heady solar]

I would know. Im trying to build a high performance printer with it. I cant give up that look though

the extruder is held on by two loose screws

the ducts are- basically useless unless its for low speed abs

[primal halo]

I'm surprised to hear that. It seems pretty ubiquitous in voron land and it has massive manufacture support. I've even seen people put it on non-voron printers. Maybe it just fills that speed benchy need, I always hear voron builders talking about trying to up the speed over all else.

[shut pewter]

It's not a toolhead for speed benchies.

It has good wire management and looks good. But those qualities also make it bulky and a bit heavy. And really limit it's part cooling.

But for normal print speeds and abs it's plenty

[heady solar]

nooooo it does not. its bulky, it doesnt have enough cooling, it doesnt support high flow hotends, and it has terrible resonances

ignore the arrow. that second hump is caused ALL by the extruder

[opal spindle]

LOL Fusion says mine is currently sitting at 160g (I have done no weight reduction so far)

[primal halo]

That doesn't sound bad, the overall package with the toolboard will probably be fairly light and I'm not sure my 60g part will be stiff enough. At the moment I have thicker walls but a more skeletonized frame.

[heady solar]

dont skeletonize plastic too much

youll suffer resonances
lighter < stiffer

[primal halo]

Mine is meant for machined aluminum currently but yea

[heady solar]

if its metal, its probs fine

[primal halo]

@opal spindle If you can beat this you'll be better than abominable

[opal spindle]

I mean..... if I print it out of plastic...

[opal spindle]

Wait I misread that as 43.3
433 is Wild to me

[opal spindle]

I NEED to know:
How did they manage that?

[spark gate]

lots of material
sb is not designed to be lightweight, its designed to be easily serviceable and good looking

[shut pewter]

That's also including the extruder, hotend, fans, and can board.

[tender token]

that is chunky

[primal halo]

My napkin math for this concept so far is: SO3 weighs 175g fully kitted, the tool board i'm guessing is another 50g, my bracket should be around 65g. Then add another 50g for misc stuff like the umbilical, bolts, beacon scanner, cpap duct etc. Should bring it to around 340g. Hopefully that package will give me a super short filament path, a durable toolhead and high temp capability. Still just a concept at this stage tho

[opal spindle]

On a slight tangent: at what point does one cross the line between an intermediate and advanced printer builder?

[opal spindle]

@shut pewter I noticed that your 6mm merch has the lightweight x gantry, how's that holding up?

[shut pewter]

Seems good still, will remove it eventually though to switch to front mount. I don't chase weight anymore.

[swift rapids]

Is there a benefit to front mount vs top mount?

[raven plume]

My understanding is (and im no expert) that with front mount you can get the toolhead com between the belts and on the carriage which helps with input shaping results.

[blissful creek]

It's also a bit of lever arms too tbh.

[scarlet wren]

personally i havent felt any difference between the two, at least at realistic printing speeds and conditions, but im sure theres some differences

[wanton shuttle]

Anyone get their FMG parts powder coated?

[dull cave]

Sorry if this has been asked before but is there an advantage to using the two F695 bearings over just buying solid idler pulleys?

[wanton shuttle]

are these suppose to be printed, in the cad these spacers show 9.85 or maybe im mistaken on what the BOM is calling these spacers out for

[heady solar]

the spacers you mention are for the stepper towers bottom printed piece. this one is to space the idler

[wanton shuttle]

could you show me where possibly? cause in the cad it doesnt have 10mm length spacers on the stepper towers

[heady solar]

sure. one sec

[wanton shuttle]

this as in stepper tower?

[heady solar]

oop- no I meant tension tower 😅

[wanton shuttle]

ohhhhhhh

thank you i didnt move stuff around to look makes sense now

[shut pewter]

All red parts in cad are printed inserts

except the spacer under that m5 bolt

[wanton shuttle]

Thank you!

[slow pelican]

anyone got clips for 9mm gt2 belts? mine keep slipping on the vztool head

[heady solar]

https://discord.com/channels/747612067951018075/1241969023265148938

9mm is somewhere in there

[slow pelican]

found it thanks!

[verbal burrow]

@frail pilot here's the thread

[frail pilot]

Oh ty

lol

I am right now shopping around for some parts and will likely do a fmg setup. Has anyone done 7075 aluminum for front idlers and stepper towers and then grade 5 titanium for x? If there are no cons in doing this then I might go ahead and get the parts made.

[shut pewter]

Ti is hevier than Aluminum, so no

[frail pilot]

Oh noted. Thought it was the other way around but that makes sense. Thanks for the response!

[shut pewter]

it has a better strength to weight ratio

[frail pilot]

Are there any adverse affects if I were to do titanium on stepper towers and idlers instead? Aside from cost.

[severe glade]

Different thermal expansion
Shouldn't matter there tho

[heady solar]

it doesnt. turtle didnt do any FEM tests on them

[wintry marsh]

@frail pilot the aluminum kinda helps act as a heat sink to cool the steppers. The top plate on mine gets warm but I have the steppers watercooled. On my other machine they get nice a warm and that does not have watercooling.

If you used TI you'll end up insulating the stepper.

We run printed stepper towers too so the heat exchange of the aluminum plate I guess does not matter too much, but something to consider.

[frail pilot]

Oh that is a really good point. I have not considered that. I probably will settle for aluminum since it's working well for everyone haha.

Thank you for your input!

[woven sand]

Has anyone been able to find the larger m5 spacers in colours other than red/black/silver? Trying to find them in a light blue and orange

[shut pewter]

Nope

[woven sand]

Found some threaded hex ones i might just drill out

[uneven solar]

do we need to adjust the dxfs for 5mm shafts vs. 8mm shafts (or long shafts vs. short shafts)?

[rugged salmon]

if you use a bearing other than an F695RS sized one, yes

[grim vine]

That's all I did

helps if you have access to a lathe

[fickle prawn]

this is crazy, the piece are hopefully correct (but I doubt it), but their price is absurd. I pay slightly more as a private to make a custom order by xometry for 3 sets… plus the ip theft (maybe they tried to give credit and decided they could somehow spell the username as turtle crawler, or maybe they thought that was the code name for the project 🤔)

[neon garden]

I'm sure they know what they were doing. Seems an odd product to offer given it's pretty niche product and those who even know to look for it would have come from here... Weird

[broken venture]

Yes, masters in the art of theft and copyright infringement XD

[distant haven]

Would you mind showing how you enclosed your printer?

[broken venture]

Nebula frame and panels?

[heady solar]

no, actually a majority buy it then come here
my theory is that it goes like this:
person watches video about mercury one.1, thinks its an interesting idea.
dismisses the idea for a while
sees listing on Aliexpress and remembers conversion, decides to buy it
comes here, to find out theyve been scammed

IMO, if we had warnings on the website and discord highlighting SPECIFIC clone manufacturers (yes ik dutch made an announcement a year ago, but no new users are going to scroll up and see that), then:
A. more people would have more awareness
B. higher likelyhood that ppl building merc on streams or videos would clarify that, but ZeroGs exposure was mostly limited to the ender-5 conversion and is in the past

[neon garden]

Fair points well delivered. Would be nice to see some YouTubers doing a full Merc build including Hydra and Nebula. Everything seems to be a Voron tbh

[broken venture]

There are

[neon garden]

Very few that I see. Feels a shame given the project and the community

[broken venture]

Ive been tempted, but im too ugly for camera

[heady solar]

no such thing. dont know till you try 👀

Too poor for a third merc

Still blowing money on Hera

[rough stream]

Maybe just more willing to spend for finer components on your existing machines?

[rough stream]

I'd love to video or stream my rebuild of Thing 1 but I have no space to record anything of value. 😭

[broken venture]

Im kinda starting at level 9/10. Not much left to stream for upgrades

[wanton shuttle]

do we use the pulley allignment tool from the merc files for the FMG just curious how i set the pulley on the 55mm stepper shaft

[broken venture]

Just get a 9mm pulley and eye-ball it

Then you dont have to be perfect

[wanton shuttle]

i only have 6mm ones on hand

[shut pewter]

That have a sight window for alignment

Just adjust as needed

[wanton shuttle]

but still use the old tool?

[shut pewter]

No

I never used that tool myself

[wanton shuttle]

also should i be routing belts before i fully assemble the stepper towers i have them together but looks like it will be very hard with it all together

[shut pewter]

Assembly them first

They are self feeding

The insert is designed to route the belts for you

[wanton shuttle]

oh okay tyty

[wanton shuttle]

Is their suppose to be different size holes for the dowel pins on the stepper plates I have one plate the center plate that the 5mm dowel pins holes can’t be reamed they are to small did I mess up somewhere? Or did send cut send miss the mark?

[shut pewter]

Bottoms are smaller to prevent drop through

The docs cover that

Or I think they do

CAD shows it

[wanton shuttle]

Shittt

[wanton shuttle]

They sent me 3 bottom plates and 3 top center plates. I have three plates with holes to small to ream, I drilled one and then reamed it. Gonna message them and see if they can send me the right plates

[shut pewter]

They are good about stuff like that

[verbal burrow]

I noticed in the M1 MG 5 Plus 9mm Top Mount Imperial cad, the stepper towers have a 30mm dowel pin for the bearing stacks, but the BOM calls for 35/36, 40, and 45mm dowel pins, what should be used here?
https://injured.lol/eqqtspkz.png

(These are both named Pin 5x30, and measure up to 5x30)

@shut pewter ^

Upon gaining a braincell and measuring the other stepper tower it shows 45, so just one of them is off

[shut pewter]

45 is used on the steppers

[verbal burrow]

Yeah thanks, gained a braincell and increase the sample size by one tower

[shut pewter]

35/36 on the xjoints

[verbal burrow]

Ahh, thank you

[shut pewter]

36 is better, but 35 works

[verbal burrow]

Yeah I found some 36

[severe glade]

so for 55x8 shafts how many 698-RS and F608-2RS do i need?

[broken venture]

You only need 2 F608s for 8mm shaft motors

Non flange ones are for the shorter shafts, like the kraken motors

[opal spindle]

do I still need to pull the hubs off of my fabreeko 9mm pulleys? they seem to spin fine as they are

[opal spindle]

as far as I can tell removing the hub doesn't change the length?

[shut pewter]

Only need to do that for live idler with 9mm belts

[opal spindle]

yup I bought these and since they they spin freely on the shaftI assume I can yank the set screws and I'm good to go? edit:fixed link

[shut pewter]

I dont think you understand what live shaft means

[opal spindle]

welp you're right I mixed that up

[opal spindle]

Sooooo I figured out this projects version of 10 mandatory Trips to Home Depot per project,
4 reorders from SCS

[rugged salmon]

@void marsh here

[crystal bane]

@shut pewter lots of good info here. im excited for my kit. after reading this and looking at CAD and the readme it make a lot more sense

[silk pumice]

I'm late to the convo, but I'm seriously considering ordering a set powder coated from DLLPDF that are powder coated. You'd have to special order them through their discord.

[still imp]

Did you get a price from them?

[silk pumice]

Not yet but when I do, I’ll let you know.

I've been waiting weeks to get rough pricing on aluminum panels

[vague raptor]

They gave me a rough idea of 100/panel when i was ordering a frame but that was a while ago idk if it's changed to something more concrete

[silk pumice]

@shut pewter - I had a shower thought this morning and wondered what you thought of this ....... So Titanium is more rigid as the temperatures rise in the chambers but Aluminum is lighter. What if we were to use Titanium parts for the stationary parts like the motor mounts and Idler Towers but then used Aluminum for the X-Joints to lighten the load (as it were) on the motors during movement? This way, as long as your rig is very square when you build and you use 9mm belts, you shouldn't have too much issue with belt stretching and alignment warping.

*I gotta find some titanium T-nuts ..... * 🤔

[shut pewter]

I doubt that it will improve much. The 2020 extrusion is the weak point.

[opal spindle]

so you're saying that the next nebula frame will be carbon fiber wrapped titanium square tube?

[shut pewter]

Most carbon epoxy has issues with high temps

[opal spindle]

https://tenor.com/view/leonardo-dicaprio-rick-dalton-point-finger-pointing-hand-right-there-gif-20349799

[grim vine]

Surely even upping to 2040 would see rigidity gains

[opal spindle]

he said most!

https://tenor.com/view/dumb-and-dumber-lloyd-theres-a-chance-jim-carrey-gif-11098164

[shut pewter]

Some have used 2040

[silk pumice]

For the gantry?!

https://tenor.com/view/damn-shookt-shocked-gif-5580082

This has @rough stream written all over it....

[rough stream]

It might have been me... at least for Y. 😅

[keen horizon]

titanium is also notch sensitive, so if a crack ever forms, the vibration will propagate it. while i love titanium, id say aluminum does the job

[stuck belfry]

Im a bit confused. What parts do I need to order for double shear with 8x55mm steppers? Does 9mm make any sense on an 180 cubed small merc?

[broken venture]

I wouldnt. Usually causes more issues than helps

6mm motion systems tend to produce better quality prints

9mm is only really needed if youre hucking around a ton of weight and flex is an issue

[severe glade]

You need 2 F608 bearings and the stepper tower prints that have f608 in their name iirc

[stuck belfry]

Pros and cons for going steel except for the xy joints?

[rough stream]

Why except the xjoints?

[verbal burrow]

Probably to keep weight down on moving parts

[rough stream]

https://tenor.com/view/logical-agree-yes-good-point-gif-3416752

[shut pewter]

I've only tested aluminum, anything else your testing on your own

Steel is prone to rusting though

[stuck belfry]

Correct guess

[stuck belfry]

I want to powder cost any metal part except for screws and rails, also not rusting steel is roughly the same price

[broken venture]

Ive been tempted to try just the bottom plate in a stronger material for the motor mounts, then keep the rest alum

Either Titanium or steel, to keep any tension flex from forming

But havent had an issue to need it yet

[surreal oracle]

Anyone putting together a group buy on the metal gantry parts currently?

[iron isle]

I was tempted to be extra and try Titanium lol

But my senses got the better of me, just because you can, doesn’t mean you should

[stuck belfry]

I am about to buy, the question is, does a buyer from Germany/Europe help you?

[stuck belfry]

I would say, it needs to fit a purpose. Either it needs to look cool, make mechanical/structural sense or needs to be prepared for hight temperatures.
I am not sure steel linear rails steel screws, aluminum extrusions and titanium plates make too much sense. You have 3 expansion values and without treatment possible galvanic corrosion.
Put yes titanium would be cool. Even better if we can get rails and extrusions too 😎

[surreal oracle]

Not sure if it would, I would think any volume discount we might get... probably not much if any on just a couple sets... would be negated by additional shipping costs. Thank you though!

[stuck belfry]

Well, I have one set for $90-ish and two for $130. It scales down pretty fast. The problem is tariffs to the USA. I can not even use any shipper, most stopped to ship to USA at all.

[surreal oracle]

Oh wow, maybe let me see what i can figure out

[verbal burrow]

If you’re in the US, SCS can do them for pretty cheap if you just countersink them yourself (not even sure if they do offer countersinking ngl)

[surreal oracle]

Thanks, I'll check it out

[shut pewter]

I'll do a few more kits soonish while I still have spacers

But once I'm out of spacers, I'm not sure what to do since they have become harder to source now

[frail pilot]

https://github.com/0xGoldstar/ZeroG/tree/main/Mods/FullMetalGantry

In terms of licensing and credit stuff, is this sufficient or is there more I should add?

[broken venture]

So you tapped the plates and put hex nuts?

[heady solar]

I believe his work with hex no??

[verbal burrow]

Think it’s just printed parts to fit hex standoffs? Not sure

[frail pilot]

I just modified the printed parts to fit hex standoffs.

Nothing else changed

[frail pilot]

No. Turtle's fits like 5.5mm iirc. Mine are 6mm

[broken venture]

TBH, you probably want to change those to passthrough standoffs tho instead of threaded, then add longer screws and T-nuts in the back for 2 more mounting points

Most go that route anyway

[frail pilot]

Yea I am thinking about doing that

I could either drill those standoffs or just get new ones lol

[broken venture]

Its probably fine for normal users, but once you hit higher tensions or GT3 belts, it will become needed eventually

[frail pilot]

Yea. I'm still a "normal" user but I suspect that will change in the near future.

[broken venture]

After about 200hz is when things get interesting

You want as much anchoring force as possible to keep your motor towers from bending up

A few people have experienced it

Again usually GT3 or 9mm

[frail pilot]

Currently I can't go very high with hz due to having top mount with 9mm. There aren't really any real toolhead projects that support top mount + 9mm. I probably will add the last two screws in the back when I switch things to front mount.

[broken venture]

9mm? yeah you want it XD

[frail pilot]

Yea

[broken venture]

Pretty sure recommended tension for GT2 9mm is around 250-300hz

[frail pilot]

Yup, I've seen that as well. Kind of wild

Not 100% sure if this project here can sustain that https://discord.com/channels/747612067951018075/1292801318326501399

This is why I want to switch to front mount due to better support out there.

[broken venture]

Front mount doesnt matter

Issue youll face is your printed toolhead

[frail pilot]

As far as I know there aren't any cnc top mounted toolheads that support 9mm. If there are then I would love that.

[broken venture]

Higher tensions and bigger belts kind need metal motion all around

[frail pilot]

Yup

[broken venture]

The VZ toolhead does if you swap the pillars to standoffs

Its full metal

[frail pilot]

Oh interesting

[verbal burrow]

Still kind of a flimsy toolhead overall though, isn’t it?

[broken venture]

Stronger than plastic

[verbal burrow]

Better than plastic yeah

[broken venture]

By a mile

[frail pilot]

I'll have to look into it. Are there any completed projects out there that I can follow for future references?

[verbal burrow]

Gold I’ll send you my vz lol

[frail pilot]

Was this the one where you made me modify some parts lol

[verbal burrow]

Don’t think so, could be

[frail pilot]

Oh I see what you did

[verbal burrow]

Either way, I’ve got the full thing, just replace the flimsy belt posts with knurled standoffs

[frail pilot]

What would you be asking for that

[verbal burrow]

Shipping probably

[frail pilot]

Those titanium screws look really nice

[verbal burrow]

I’m doing front mount breakneck, have no use for a top mount

[frail pilot]

Lmk details and whatever and I can check what shipping is

Or wait

Aren't you flying in a couple months?

[verbal burrow]

Bunch of places, none near you

[frail pilot]

Cheaper to ship from USA

It's fine

[verbal burrow]

We can go to dms with this to not clog up the fmg thread tbf

[frail pilot]

Sure

[verbal burrow]

yeah I classify USA as near you

[rough stream]

I wish I had your sense of responsibility... 😅

[shut pewter]

@frail pilot yeah for 9mm belts you want to modify the printed insert for another m5 spacers anyways, though that requires nebula or longer y extrusions for the rest mounting point.

[frail pilot]

Oh yea I see what you did. I suppose I'll do that.

Did you also mount the last screw?

[shut pewter]

That's still just normal

[broken venture]

I made that one also a passthrough screw on mine

Doesnt hurt

I wanted the 5 point mount for speed run rigidity

I just kept all mine M3 tho, so not as strong, but more holding area

Dont know if that helps it if at all but doesnt hurt XD

[iron isle]

Those are gorgeous!!! Wow. I’m over here still waiting for my 400x400 bed lol. Ordered it 6+months ago now.

But, good news is I’m working on getting our berserker rails MGN12-H in 450, and 500 respectively.

Im wanting to go 9mm belts on my Nebula. Any tips or suggestions on that?

Happened to get a Takeoff and CHUBE just for the occasion. Heh heh.

[surreal oracle]

I ended up ordering through SCS for a reasonable price.

[stuck belfry]

Can you tell me the price, to have a benchmark?

[surreal oracle]

130 usd for 2 sets with x for top and front mount

No countersink I will have to do that myself

[stuck belfry]

Thx. The countersinking I plan to do myself too

[rough stream]

If you do go 9mm, I suggest front mount xjoints. Unless you are going 9mm E34M1, there seem to be more 9mm options for front mounted toolheads that work on the Merc than top mount.

[rough stream]

I meant to ask if you pushed these changes yet to the plates. I need to go check.

[shut pewter]

I need to work on updating the 6mm files still, wanted to get my cantilever z project out there before spending time on that.

Just posted those files, so I can go back to metal gantry to wrap that up.

[crystal bane]

Tonight it all gets installed!!

[stuck belfry]

That laser engraving looks neat!

[crystal bane]

thanks its my logo 🙂 im going for my business theme with this nebula, my company colors are red, black, white and grey so it works out great on this build 🙂

[shut pewter]

We know

[iron isle]

Will do!

[crystal bane]

9mm FMG goodness 😍 😍

[ornate jolt]

What type of results are folks getting? I’m eyeing this for my pro nebula and figured 6mm belts would be more than enough with the smaller size.

[slow pelican]

I didn't get great results from 9mm, probably built something wrong or tolarences from my prints or the cutter

[compact prairie]

if you can't get a good IS graph on 6mm belts, moving to 9 is a fool's errand. Wider belts are for pushing performance, but even narrow belts will reveal mechanical issues.

[ornate jolt]

But this one goes up to nine

[compact prairie]

I understand the appeal

[amber cobalt]

Ya. I'm waiting for the 25mm v-belt mod. 🤔

[stuck belfry]

Isn't linear drive cross gantry with halo support frame the next Evolution?

[rocky heron]

Hi guys what print settings are used

Reference the ZeroG settings?

I'm sure this has been asked a lot i apologise, my search function isnt working

[rocky heron]

Yep thought so!

Thanks :D

I did an oopsie for one of the x joint pieces, it imported upside down and failed mid print

ah wells

thank god for exclude object

[rocky heron]

I think I found an error in the BOM

9mm kit needs 24 f695

That sucks 😭😭 I gotta order them and wait now

[spark gate]

Where do the other 8 come from?
You need 8 for the drives
4 for the xy joints and 4 for the tensioners
The other 8 you probably think of are only 695
No f

[rocky heron]

4 on the front towers

[spark gate]

Nvm
Drives need 12

Forgot 4
Mb

[rocky heron]

6 per stepper tower, and 4 per X joint

[spark gate]

Yeah

[rocky heron]

Just thought I'd share it here and have the BOM updated for others, wouldn't usually be an issue but I'm building a fresh nebula from scratch

[rocky heron]

Just got my linear rails in, so I'm going to clean and install them after some assignment work

[rocky heron]

Pretty nice stuff @shut pewter !

Thanks for your hard work designing this

[soft pagoda]

Translation

Text translated: DIY Self sourced full Metal Gantry motion system

I have been thinking about how do metal Xjoints to go along with the metal stepper mounts I designed for awhile, as well as front towers. Keeping with the design concept of laser cut plates with off the shelf spacers, I had to lower the X gantry and belt path. I also decided to support both top mount tool heads with standard Zerog belt paths, as well as front mount style tool heads. Both require different Xjoint plates.

Full step assemblies have been added for all of the standard configurations, including the belt paths for both the 5 Pro and 5 Plus. This will allow you to drop them into the Mercury one.1 Cad assembly with minimal work.

I have been running the 9mm belts on my red merc for awhile now, and have installed to verify fitment of the 6mm parts on my other mercury, but have not had time to print with the 6mm parts yet.

The 6mm Xjoints are 5 grams lighter than the printed xjoints, per side.

[compact prairie]

what kind of bot calls translation from English to English

[heady solar]

it mustve been a mistake

[velvet raft]

I'm a little bit at a loss for my build. For the right stepper tower the pulley is not aligned with the flange stack (hopefully visible on the photo, it is approx. 3-4mm). The pulley is already at the lower end of the stepper shaft (42STH48 2804AC-R 48 with 2.4 shaft, 6mm belt, F695 bearings). I have looked now for hours in the drawing, measured all parts and so on. So what did I oversee?

A 2nd topic is that I have a 1 - 1.5mm play on the X-Joint pulleyes. Is this wanted or also a mistake on my side?

[wanton shuttle]

that could very well be the fact it is funossor parts

[velvet raft]

You are right it is funssor and I'm not really happy with it. Howerver, I have it now and need to live with it 😉 The top plate is exactly 3mm and the bottom exactly 6mm (so 2x3mm). The position of the pulley is defined by the shaft. Since the stepper is plane on top this cannot be the problem. The position of the bearing is defined by the printing and the height of the bottom plate, which is from my measurement also okay.
So, where do I loose 3-4mm? I must oversee something.

[severe glade]

For the play you just need some washers

[severe glade]

Flip the pulley, screw part goes up

[broken venture]

Nooo, not another funssor victim

[velvet raft]

I had this idea too, it is not convenient because you need to exactly align it before assemble the top plate with the top printed part (after you have no access to the screws from the pulley), but it will work. However, I want to understand why.

[velvet raft]

Hmmm I have read across here and must have overseen people complaining to it.

[severe glade]

There have been quite a few cases

[broken venture]

Their parts are not ZeroG parts XD

[velvet raft]

Okay and now hopefully documented here for all others 😉 The quality is from my understanding (I'm not a pro) not bad. Some parts are missing, one countersink forgotten and the service is b******t.

[severe glade]

Im pretty sure i managed to adjust my pulley on the assembled stepper tower through the hole in the front of the printed part

[velvet raft]

Thx, I will give it a try when I'm back from work in the evening.

[wanton shuttle]

Did you print the metric or standard parts?

And you should have access to the grub screws on the pulley after installation

In my case I do

[velvet raft]

As far as I remember, I taken all files with metric. Will doublecheck this evening, I'm on the way to work.

[wanton shuttle]

And that picture you posted is of the left stepper tower right?

If it is in pretty sure that part is 180 degrees the wrong way if I’m seeing that correctly

Nvm that’s the right side

[velvet raft]

Shortly you shocked me, it is before my first coffee 🤣

[velvet raft]

Thanks for all who point me into the right direction. I have spent some more shims for left & right X-Joint. Then I have changed the pulley for the right stepper "upside down" (I need to push it to the top, which can only be done in disassemble version) and now it looks good. Afterwards I measured the height of all pulleys and bearings to be sure they are on the same height and re-belt.

However, still curious why to change the right pulley 😉

I have also found now the complaints about funssor and must be sorry to buy such stuff and annoyed you with it. Next time I give funssor a wide berth.

[shut pewter]

The pulley height gets set with it assembled and installed

That's why it has the window cutout

[velvet raft]

Yes I know but for whatever reason that does not work in my setup 🙁

[wanton shuttle]

Your running normal motor shaft length aren’t you?

Not 55mm

[velvet raft]

Exactly, I have a 2.4 shaft, 6mm belts and metric version.

[delicate river]

Is there anyone here who could machine/cut the parts for the fmg? I would pay ofc but I’m not certain where I could go near me to get that done

[verbal burrow]

Where are you located?

[delicate river]

Oregon

Portland area

[verbal burrow]

Sendcutsend can cut them

[delicate river]

I’ll check them out thanks!

[compact prairie]

SCS is the goat for some things, I've not had an issue and the competitive robot sport in north america would probably be dead without them lol

[verbal burrow]

Yea wish we had them here, I’m having a friend mill my stuff

[shut pewter]

2 things, first hold off on ordering until I get the update posted.

Second I will be selling one more batch of kits later this year through DMs in a waiting list. But that's probably a 2 month wait because I'm just slow. Also often juggling to make projects, so processing them takes me awhile. But they are fully finished and include all the hardware other than bearings and pulleys/idlers

[still imp]

@shut pewter - what sort of changes are going to be in your update?

[verbal burrow]

New bearing spec, afaik just the motor towers changing?

[shut pewter]

Yeah that's the main thing, and adding metal Gantry spacer files for 9mm.

[severe glade]

ohhh thats nice

[delicate river]

Could I be put on the list for one of those kits? I probably wasn’t going to order it for a while anyways, I’m a broke 17 y/o college student lol can’t afford it atm

[shut pewter]

Send me a DM, I'll get back to you after work

[delicate river]

Just did, thanks

[shut pewter]

I'm just finishing up my lunch break, then back to work

[delicate river]

👍

Whatcha eating

[shut pewter]

Taco bell

[delicate river]

Neat lol

[rocky heron]

Hi guys! Having a few issues currently

One is a question for @shut pewter

These grub screws are hitting the belt, I'm using Mellow GT2 pulleys, is this just a case of use smaller grubs?

Also my other issue is more external-ish but the 9mm EVA 3 has two problems, the belts seem to sit too high on the body

[broken venture]

Well, first of all you are going to have serious problems with that belt

Its not flat at all

You are going to eat it up so fast

You also should probably order shorter grub screws if theyre poking out

[shut pewter]

Either order shorter set screws or file/grind them down

[pallid quest]

Getting motivated to get my nebula frame finished, I have local supplies gates belt options now I am taking so long. 9mm fmg on a plus size printer, gt2 closed loop belts or gt3 open loop belts?

[shut pewter]

For 9mm I wouldn't do gt3 again

Crazy high belt tension

[rocky heron]

That's the main issue.. I don't know why

I'm using the 9mm Eva mod, is there another people are using?

[shut pewter]

I've only used front mount toolheads with 9mm belts

[rocky heron]

The belts are mounting too high on the EVA front module

[shut pewter]

At4, takeoff

[rocky heron]

I see

Maybe I'll need to make it myself haha

[shut pewter]

I have never looked into the Eva 3 CAD for the merc

[rocky heron]

I've been using EVA 3 from Jon for the last 3 years almost on my basic merc

That's why I wanns stick with it, it's worked really well for me but it seems like the belt grooves are positioned incorrectly, can either adjust the spacing of the gantry itself and shit it downwards or redesign the belt mount

Also what frequency are you setting your belts at? I'm using the double shear support

[shut pewter]

Check the pins

There is a calculator

Looking at the screenshot of the CAD for the 9mm eva3 mod, might not be space to move to the belts down probably without more changes

[rocky heron]

Damn...

So according to that calculator, if measuring at 150mm between front tower and idler pin like standard Merc docs state

200hz or so, that's crazy haha

[shut pewter]

Yeah 110 is recommended due to single shear

Can bend the shaft

[rocky heron]

All better!

[shut pewter]

That looks better

[rocky heron]

Very happy now lol

The link to the file is in the EVA 3 thread

If anyone will find use in it

[ornate jolt]

Thats awsome. I hope it gets uploaded to github as well. Thanks for fixing that, Jayden.

[rocky heron]

It's okay! Let the 9mm belt live on :D

[supple quartz]

just a quick question regarding the motor mounts. I have F608 bearings and have printed off the parts. Do i snap out the bit where the bearing sits on the bottom part of the printed part?

disregard, figured it out

[supple quartz]

but apparently im going to need to take out some of the champher on the stepper mounts, as they dont suit NSK f608zz. Has any one else experienced that?

[supple quartz]

There’s a chamfer on the slot, that doesn’t allow the bearing to sit in nicely

[compact prairie]

it's for the flange I don't understand what you don't understand

[shut pewter]

Bearing goes into the metal plates under the printed insert

And you have to use a flange bearing

[supple quartz]

ahhh i get it, facing down, gotcha. sorry I was like am i just a dumb ass or unable to think about it logically

thanks turtle

[stable iris]

Would this parts group buy be for Europe or USA or both? I'm in, if western USA is doable.

[verbal burrow]

Don't think it's a parts group buy, it's turtle machining them and selling full hardware kits including hardware for them afaik

^ And turtle is in the US

[shut pewter]

Yeah I just order the plates from SendCutSend and finish them, provide the hardware

I've just been juggling projects, trying to sort it how many kits I can actually do with the hardware I have left

[verbal burrow]

And then new 9mm stepper towers ;)

[stable iris]

Oh OK, that sounds good. I'm in if there's enough. 👍

[shut pewter]

Yeah just send me a DM and I'll add you to the list

[ornate jolt]

I'll buy a few sets too. 😄

I was going to see about ordering some this week.

[wanton shuttle]

wait whats this list for

[ornate jolt]

What channel are you in? Its for that, silly.

[wanton shuttle]

yeah but can i get this before its actually updated lol

or will he drop update before he ships these out

[ornate jolt]

Probably not. If you want it sooner you need to order it yourself. If Turtle is busy, I would give him 6-12 months. 😄

[wanton shuttle]

Lol i can self source, i was just wondering if this was gonna earlier on the timeline

[shut pewter]

I just keep putting off uploading the files now because you pointed out that printed insert height issue which I some how missed, and I need to fix on this update and redo all the 6mm exports again lol

and to many projects

thanks for pointing that out by the way, no idea how I missed that

[wanton shuttle]

Your good i fully understand, we all have our lives outside this stuff. im just grateful to be able to use the stuff you design

[shut pewter]

I do plan to push the update before I send out more sets

I need to make sure the correct files are out there first

[rocky heron]

Oo damn I missed this

Wait so is there going to be a big change to the 9mm setup? I just finished it 😭

[shut pewter]

Nothing big, just the stepper plate bearing setup on all l6 and 9mm

[rocky heron]

Ah i see

Is it normal for a fresh belt to shed during initial use?

I dont see rubbing or grinding anywhere

[shut pewter]

If a bearing stack is sitting to high or low compared to the rest for that path it can create more issues

[rocky heron]

its like this white gunky stuff

looks like its coming from the back of the belt

[ornate jolt]

Is it a glass fiber belt or the... whatever it is pdm or something like that

[spark gate]

Only printed parts or also metal parts 🤔

[shut pewter]

Smaller bearing cutout in the metal stepper plates

[rocky heron]

its a gates GT2 from mellow? or trianglelab i cant remember

[verbal burrow]

EDPM belts

[rugged salmon]

how can I differentiate the 2 different stepper mount plates?

[astral ore]

If I remember correctly, the plates that go on the top and middle have a slightly larger hole where the dowel pins sit. Somebody correct me if I’m wrong though

[severe glade]

Correct

[broken venture]

The bottom plate has smaller holes to prevent pin drop

[rugged salmon]

thanks!

going to countersink them tomorrow

[ornate jolt]

If I have send cut send tumble the plates to remove the burs, will it cause any fitment issues?

[keen horizon]

typically that process only knocks off half a thou, probably less to internal holes/features

do we have any feedback on the funssor parts? its a really cheap option since they mass produce, but know the tolerances might be loose. anyone using them with success?

[verbal burrow]

Funssor is violating the zerog license, and just grab STL's without considering fitment or the shrinkage that's built into those STL's in the case of zerog parts, they should be avoided

[compact prairie]

tl;dr: Do not buy, do not use funssor parts. Doing so will net you no support, no friends, and poor results.

[broken venture]

We will shun you XD

[flint notch]

I'm getting lost in the sauce with ordering the extra shims. M5x0.3 Shim,M5x0.5 Shim,M5x1 Shim can someone help me out . I can find almost all the parts on amazon but the shims im not sure.

[compact prairie]

Washers on amazon come in thicknesses, I just buy 5mm washers. Sometimes if I want to swing for same day or whatever I will get 3/16" instead (same size basically) if those are available and 5mm are not.

You can absolutely get 5mmx0.5mm washers etc there.

[flint notch]

I find M5x10x.05

[compact prairie]

You sure about .05? If you mean 0.5 then bam you got your half-mm spacers

Like, I am not doing anything special with searching, are you not in the US?

https://www.amazon.com/uxcell-Stainless-5x8x0-3mm-Electronic-Automotive/dp/B0C3TZ1FL2?

I just searched "m5 washer 0.3" and "m5 washer 0.5" and oodles of results here.

[flint notch]

I searched using shim and crap I need to wear my reading glasses now lol. I swear I saw .05 lol. Thank you.

[shut pewter]

just search m5 shims

[flint notch]

It was my bad eyes that let me down. I was looking for .05 shims lol.

[rocky heron]

Hey guys something I've figured

Make sure that your stepper towers arent touching the frame

I had one touching

This is a before of my Y axis

After

Not perfect but MUCH better

[vague raptor]

But they're mounted to the frame, maybe im misunderstanding

[rocky heron]

The top of the mount assembly will resonate on the upright

[orchid marsh]

Ohh very nice. Will be adding to my list of things

[keen horizon]

@shut pewter , i reached out, but not sure if you received notification. id be down to either buy plates and hardware, or even just the hardware if you have them packaged. if theres a list, id like to be on it 🙂

[stuck belfry]

Hardware changes with the desired setup (6mm, 9mm, double shear, kind of stepper motors). You need to know what you need.

[keen horizon]

Yea it just seems like buying seperate will net you with alot of left over. I'm Goin 9mm double sheer. I can handle bearings, and gears, and printed parts of course, but thought the rest were universal regardless of config (I may be incorrect). But if anyone gots left over for 9mm I'll happily purchase!

[severe glade]

Are you in the us?

If you are in eu i have basically a whole 9mm double sheer fmg

[shut pewter]

Going to go through my DMs for order requests this weekend

And I'll only sell complete kits, with what ever spacers I have left. Once I'm out of spacers I'm not sure what the plan is

[keen horizon]

appriciate that, but yea im in California

[indigo orbit]

just got my parts from send cut send

just have to order the rest of the hardware now to buikd it

[shut pewter]

FMG Github has been updated, the old files are still in the old main branch. I pushed this change to V2.0

I will rename the old main branch to V1.0

[wanton shuttle]

Witch plates can be reused in the update?

[shut pewter]

everything but the stepper mounts

[indigo orbit]

i think i did the rwv be mounts not 100 percent sure

whats diffrence

rev b but ill look if not ill order new plates

[shut pewter]

huh?

[astral ore]

I think they’re talking about version 2

Viper version 2 just got released. When did you do your parts?

[shut pewter]

rwv?

[astral ore]

Typo. Think they were trying to say rev b

[shut pewter]

ohhh

the top plate looks very different with a big notch

[rocky heron]

Has anyone had issues with fushi ABEC9 bearings failing after a very short time?

I have my belts tensioned to 230hz and this is the second time they've started clicking

[indigo orbit]

i got them off github

ill have 2 order the new top plate and the optional parts

[ornate jolt]

I haven’t tested to that tension level but Fushi has treated me very well so far

[rocky heron]

Interesting.. I don't know if it's the oil leaking out from the 65c chamber temps

[topaz agate]

I've got 8mm shaft steppers and both the bearing and the pulleys arent a slip fit like I had with the 5mm ones. would you slightly sand the shaft or try use heat to get it on?

[topaz agate]

ok pulleys are on after just keeping them on the printbed for a moment, they're aluminium. bearings are stainless I supposed so they probably need more heat to expand a bit

[verbal burrow]

Are they ZZ bearings?

[rocky heron]

No they're RS

[shut pewter]

I've only used cheap abec1 bearings, just what ever I find cheap on Amazon

[verbal burrow]

Weird, i only know ZZ bearings to be leaking grease, RS shouldnt

and yea i dont even think my NSK bearings have an ABEC rating, doesn't really tell the full story of the bearing, just that a few parts have good tolerances

[shut pewter]

Looking up what I can find on nsk 695s looks like abec1 is standard

They use class zero

[verbal burrow]

Probably, they also have their own tolerance class names, im not very worried about it

[shut pewter]

Which I assume is class normal

[verbal burrow]

Yeah, still have to reach out to alchemy to get my F695's theyre harder to find, after that my FMG hardware is all ready to go

[topaz agate]

Opted for sanding the shaft, wasn’t much

[shut pewter]

I've had to sand most of my stepper shafts

[topaz agate]

How did you do it? I have just connected it and dry-homed without the belt till it was sanded enough

[shut pewter]

No power

Just by hand

[topaz agate]

Oh 🤣 I was just worried I’d sand it uneven

[broken venture]

I never had to sand for pulleys, just a couple dual shear bearings

[topaz agate]

holy shit I want my LDO steppers back, the omc steppers are much louder - or maybe its just the tighter belts?

[shut pewter]

Performance electronics tend to be louder

[topaz agate]

the 8mm shaft was the only change tho, and I've tightened the belt slightly stronger, this must be it, I cant imagine they sound so extremely different with exactly the same winding specs

[simple kraken]

Out of curiosity, if I want to use the old style double shear (V1 lower stepper plates with a flanged bearing - I have plenty on hand) the V2 is all I would need to change for the cutout correct? Geometry and such remained the same otherwise?

[shut pewter]

No need to update then

[simple kraken]

Perfect - thank you

[shut pewter]

The update with the bearing change made it easier for me to modify the printed files for the 4th both mod and maintain it

And the top plate isn't a huge improvement, just use a ball key or L key

Or both

Still need a ball or L key with the update anyways

Just gives a bit more space for the ball key

[simple kraken]

Fair enough. Got it. I wasn't tracking the need for the ball end still, all good regardless. I like how they look and I need to order some more parts

These will get me over the minimum order

[shut pewter]

That works then

[simple kraken]

I also like how they look

[shut pewter]

Only reason I didn't do that before, was trying to keep the bom count on dxf files down. 4 plates are cheaper than 2, though that price difference isn't as great anymore through SendCutSend. And the bearing spec change is more important than saving a couple dollars

[simple kraken]

agreed - one part is $30, add a second for $9 more . . . .

I do like how all 3 are different on the new plates though. I did not catch the difference when I mass countersunk the plates and had to re-order the bottoms. The new setup will prevent folks (me) from missing that

[shut pewter]

You can still mix up the bottoms.... I did already lol

[verbal burrow]

I’m excited for my thick boy bottom plate

[stuck parrot]

Hi guys, I’m on the fence of going to build the 9mm fmg set, with 4th bold mod and double shear mod.(thought if I jump the gun, I’ll go all out)

I’ve downloaded the latest dfx files that has been updated last week, to send it to my laser guy.

But is there an all out bom list ör a detailed build topic I can use to check for parts and motors etc. In my search I saw something about a miss count with the bearings.

Thx in advance (fyi I have a lot of spare 4040 extrusion, any ideas if I could use them for rigid frame or enclosure attached to the Ender 5 plus frame?)

[verbal burrow]

Did you get the new revision of plates?

https://github.com/TurtleCrawler/Mercury-One.1---Full-Metal-Gantry/blob/V2.0/FMG Guide.pdf

(from the V2.0 branch)

[stuck parrot]

Yes I think I did, I’ll dubbel check it when I’m back at my pc.

[shut pewter]

Everything should be updated and correct now

But it's still possible that I missed some small details

[stuck parrot]

Allright, I double checked and it’s version 2.0 👍🏼

[sour rock]

do you have a changelog?

[shut pewter]

No, might add one later. It was just the stepper towers, a few printed spacers to make them all the same od. And some bom and CAD fixes

Nothing with the metal parts changed on the xjoints or front towers

[sour rock]

perfect thanks

[stuck parrot]

Good to hear, I’ve just ordered the parts at the laser guy, let you guys know when I receive them. Now going to see what I need more haha. Any stepper motor suggestions and tool head suggestions?Currently have a full stock Ender 5 plus with btt board, e3d hemera and klipper to donor for the fmg.

[wanton shuttle]

Whats the suggested place to buy the 635rs bearings for double shear?

cant find them from fabreeko, west3d or kb3d

[shut pewter]

I buy pretty much all of my bearings from amazon

[broken venture]

Wait, do I need new bottom bearings for the new plates?

Didnt look that far

[wanton shuttle]

I cant remember what bearings are in my current setup will find out when i tear more apart to see if they are 635rs

[broken venture]

I have 8mm shafts

[wanton shuttle]

yeah you have the other bearings

[broken venture]

https://tenor.com/view/pakistan-cricket-fan-pakistan-fan-cricket-angry-fan-angry-fan-angry-man-gif-19825067

Welp, time to order some new nsk's XD

To the misumi website I go

[wanton shuttle]

that website is confusing for me to find parts on

[shut pewter]

yeah much more common sizes now

[broken venture]

Is it 698-2RS?

698RS doesnt exist XD

I think this is the correct one

$6 a pop, damn

Alright, should be good to order

[wanton shuttle]

i dont see rs from nsk at all on misumi

[broken venture]

Dont think there is

[shut pewter]

check ezo

ezo is another high quality brand

[verbal burrow]

definitely does, smh

i bought some for like $15/pc

https://e-z.tools/25q3c1df.png

Misumi's NSK collection is quite lacking imo

[wanton shuttle]

those ezo brand are much less hurt on the pocket

[verbal burrow]

i spent ages to find RS versions of all the NSK bearings I needed

Ends up being $260 for 20x F695, 10x 695, and 2x 698

[wanton shuttle]

they dont have them on misumi i dont think

[verbal burrow]

Yeah they don't, they had a lot of RS NSK's missing

Had to find other places to get them, think i ended up only being able to find the F695 RS on misumi, rest were on other sites

The F695 RS from misumi are also double the price of the ZZ's
https://e-z.tools/oox3u7eg.png

[wanton shuttle]

i cant find f695 rs from misumi

just steel

[verbal burrow]

(they're labelled F695-H-DD1)

Not sure if all the misumi sites share inventory or what, but i cna find it on the uk one

[wanton shuttle]

no flange

wait pic arent accurate on misumi

[verbal burrow]

Yeah, F695 will have a flange

[astral ore]

Dang yall doing nsk for your flange stacks?

[verbal burrow]

I'm doing NSK for every bearing, apart from the ones in my rails 😂

[astral ore]

I ordered some 635ZZ for double shear a while back

Now I feel like I should get some f695s 🥹

[verbal burrow]

https://e-z.tools/to883quf.png

[astral ore]

Looool so true

My debit card hates this place

[wanton shuttle]

https://tenor.com/view/were-rich-jack-harlow-wasted-youth-song-we-got-cash-lots-of-money-gif-4008713716352412007

[shut pewter]

I'm not taking the blame for anyone ordering nsk bearings 😂

[astral ore]

I’ll just tell my wife Nick said I needed them this time

[wintry marsh]

No more flange bearing for double sheer in the bottom plate? Is the double sheer now in the plastic for both 8mm and 5mm now?

I went and read the docs instead of being dense. I like how the bearings are supported now with the 5mm.

[indigo orbit]

im reodering my 6mm FMG parts this week to the proper v2 parts didnt realize @shut pewter changed them after i placed my first order but have everything else to start printing the parta

[shut pewter]

Yeah I was posting a bit to let people know that I was working on pushing that update. Just took a bit longer than I thought

[indigo orbit]

its all good

[stuck belfry]

I'll stick with v1 for now as full full metal version.

[wanton shuttle]

will v1 FMG take v2 printed parts?

when i swap out these stepper towers if they are i can just take all of it and swap it to my first merc

[shut pewter]

Probably? Just won't have the proper bearing supports

[wanton shuttle]

Their is 4 files in the 6mm top mount cad section witch of the 4 is the correct 2 files?

[shut pewter]

Depends on plate thickness

3mm or 3.175mm plates

[wanton shuttle]

Yeah i need the imperial cad but their is 4 files their or are two just duplicates?

[shut pewter]

No

Read the full file names

[wanton shuttle]

The full file names are the same

OMG

nvm

im sorry

pro vs plus.....

genuinely feel like a numbskull now

[shut pewter]

You were making me question my own sanity as well 😂

[wanton shuttle]

Yeah sorry about that, ill exit now lol

[jovial isle]

So I'm looking to combine a VZ-CNC head and FMG 9mm on my updated M1.1 build.

I see folks mentioning replacing the front pillars with stand-offs to ease belt setup, but I'm more concerned about the belt angles.

The Pillars seem to be rather far forward of the belt path, I'd think this may cause rubbing on the bearing stack when the toolhead is to the ends of the X axis. Am I overthinking this?

[shut pewter]

You need to center the gantry on those m5 bolts

[jovial isle]

Ahhh, I see it now. Yeppp gantry is out of alignment, thank you

It's low too. Must have still been in the default position from the non-FMG cad

[shut pewter]

I also just noticed today that I made some errors in the BOM when I updated it

yeah I didnt set the xjoint locations to match the gantry location in the fixed mercy cad, just picked a location when I did the belt path file.

and this mod does lower the entire gantry a bit as well.

[jovial isle]

magic when you properly align things.

[shut pewter]

Maybe I'll add gantry extrusions and rails on the next round of cad updates

I can work out how to add those in a parametric way to save out to all 16 step assembly files.

[jovial isle]

I'll look for an update. Ordered spacers and stand-offs a few days ago.

[shut pewter]

I need to work on updating Fraks before I do anymore updates outside of minor fixes like the BOM counts on the M3 hardware I missed

[jovial isle]

Need to build a Fraks too, so I'll be on the look out for updates.

[rough stream]

I was going to mention that 38mm standoffs fit well but then I thought I misread something, deleted it, rewrote it, thought I misread it again and deleted it. 😅

What I was going to say is that I, too, am planning on doing a 9mm FMG with the CNC toolhead on one of my Mercs but I want to use 5mm ID aluminum spacers like I did on the FMG instead of printed spacers. The 38mm standoffs, though a little difficult to find, fit without additional shims or flipping the bottom plate (which fit 37mm ok and are easier to find but I had to add a 0.3 or 0.5mm shim, I can't remember which)

[simple kraken]

where did you find the spacers?

[rough stream]

The spacers or the standoffs?

[simple kraken]

standoffs please

I have plenty of shims

😂

[rough stream]

Oh I got them on eBay

[simple kraken]

Awesome, thanks. I have a few of the 37mm ones and would love to ditch the shim. And these would match the remainder of the standoffs.

[wintry marsh]

I just found this on AliExpress:
C$0.65 | 1/2Pcs M3 Red Black Round Aluminum Standoff Column Rods Aluminum Spacer Coupling Column for RC Multirotors OD=5mm Length 4-100mm
https://a.aliexpress.com/_m07YAVb

If you message this seller they will make you 38mm stand offs

They are making me some right now

My stock "posts" are bent from the gt3 belts.

[jovial isle]

I ordered some 35mm standoffs and figured on stacking shim washers on both ends to make up the difference. Not ideal but doable. Or maybe design some up and have PCBway make purpose made pillars. Yet to be determined.

[rough stream]

Make sure you measure them. I had a seller on AliExpress tell me something similar when I needed custom standoffs and they sent me a standard size that were 1mm off.

[rough stream]

I would have totally tried them for some red ones. Luckily, I have some extra I might polish and anodize red myself. 👍

[rough stream]

I'd be interested in some 9mm pillars. 😁

[heady solar]

next vid Mandic builds FMG Nebula?!?!

[jovial isle]

Not next but soon. Compiling parts and planning at the moment. Probably January or February.

Be the update to my Merc1 video.

[astral ore]

Awesome. Can’t wait to watch it

[rough stream]

Any hints if you're doing any out-of-the-ordinary customizations to the build? I mean outside of the 9mm and CNC toolhead. 😅

[jovial isle]

Flap Controlled CPAP and Kraken motors will be on the menu. I'm sure there will be more, but for now I'm ensuring I've got the "basic build" ironed out before I go crazy with changing things.

But it IS getting a Magneto cutter...

[heady solar]

nebula too or?

metal hydra 👀

very hyped

[rough stream]

I really like the 'CFLAP' 😅

I have it on my 3 Nebula 370 builds but I'd like to switch to a more compact, aesthetically appealing version someday.

[jovial isle]

Nebula, yes.

[broken venture]

You dont use knurled for the added grip?

I can see belts moving with smooth

Unless its less of an issue with 9mm

I just used 37mm standoffs and a washer

[rough stream]

I opted for smooth because I'm planning to use aluminum spacers with a 5mm ID to space the belts apart. So, the belts won't move once the 5mm ID spacers are in place, plus using 38mm standoffs means I'm working with 20mm of space to fill and I like that it works out even like that. 😅

[verbal burrow]

I might try integrating CFLAP into my build, space is kinda rough though so a more compact version would be nice

[stuck parrot]

Are there any FMG 9mm builds here i can read up to? Looking for some insparation and "guidance" with some things. For instance i have 2 e3d hemera extruders im really happy with. But they are a bit Bulky - but would like to start first with them.

Just looking i am capable enough to adjust the EVA 2.4 hemera to the FMG 9mm version..

[slow pelican]

anyone running front mounted ganteries? is there a difference in plates/printed files?

[broken venture]

Just the X-gantry plates are different

Everything else is normal

[heady solar]

@opal spindle has build log with similar extruder here:
https://discord.com/channels/747612067951018075/1407228050017619999

[opal spindle]

you might also be interested in my toolhead design:https://discord.com/channels/747612067951018075/1441929339066126549
There's only one part that needs to be changed to adapt to any toolhead/extruder combo I'm aware of

[opal spindle]

What bed leveling system are you using? I don't have a hemera to measure but as long as the mounting hole spacing is comparable to the SO3's (it looks like it might be) the only concern I have is the nozzle height offset if you're using a eddy current sensor

[stuck parrot]

I’m for now on the standard bed leveling system from the ender 5 plus (2x z stepper and bl touch) but thinking of going with a beacon/eddy. Which measurements do you need to verify?

[opal spindle]

The mounting hole spacing and height of the bottom of the nozzle from the the bottom mounting hole

[stuck parrot]

Im going to measure tomorrow and come back to you.

[opal spindle]

Ok

[wanton shuttle]

I feel like i remember seeing at one point that genuine gates idler's required a smaller diameter shim, if that is correct, what diameter size shim do i need?

[shut pewter]

Any idler really

7mm works well

[wanton shuttle]

Where are you sourcing those from, probably havent since you have stuff stock piled

[astral ore]

https://a.co/d/jj0aRhN

[verbal burrow]

I think I bought some 5x10 instead, guess I’ll order some new ones

[shut pewter]

9mm? then you are fine

[verbal burrow]

Ah nice

[stoic hound]

do you all know if m5X8mm shims would work with gates idler, can'T seems to find 7mm ones in canada

[shut pewter]

RC cars often use 5x7 shims for axle bearings

[ornate jolt]

What bearing retaining compound is suggested? Looking for green shows 10 different kinds. :0
https://www.amazon.com/Retaining-648-Cylindrical-Components-Assemblies/dp/B0CHWFVV2Q

Product Max Gap Fill Max. Temperature Key Characteristics & Application
603 0.1 mm (0.004") 150°C (300°F) Low viscosity for close-fitting parts, good for use where surfaces cannot be consistently cleaned (oil tolerant).
609 0.15 mm (0.006") 150°C (300°F) General purpose, low viscosity, designed for clean surfaces, often used for augmenting press fits.
620 0.2 mm (0.008") 230°C (450°F) Highest temperature resistance of the group, high strength, designed for permanent bonding of cylindrical parts exposed to high heat.
638 0.25 mm (0.01") 180°C (356°F) Highest strength for general industrial applications and large gaps, high viscosity, rapid fixturing, tolerates minor surface contaminants.
648 0.15 mm (0.006") 180°C (350°F) Fast-curing with high strength, excellent for stainless steel and other passive metals, primerless.
680 0.38 mm (0.015") 150°C (300°F) Largest gap filling of the group (along with 660), medium/high viscosity, used for slip fits and worn assemblies to restore fit.

so..... maybe 620 or 648?
620 for temp, 648 to work with the stainless on the bearing surfaces?

[blissful creek]

641 loctite.

[ornate jolt]

I know it has been asked before and I tried searching but haven't found anything so am dumb, but the printed parts of this only provide support to hold things in place right? Not any structural strength? So if I use ABS, thats OK? Or do I need to use ASA-GF?

[shut pewter]

yup abs is fine

[ornate jolt]

Thanks, Turtle.

[shut pewter]

asa is probably better, but in the stepper mounts they just space the bearing stacks and help guide the belt

[ornate jolt]

I have more colors of both but only black and white ASA-GF

Did you have an opinion on the bearing compound? Is 641 the right stuff?

[shut pewter]

as long as its a bearing retainer its fine

dont over think it

[ornate jolt]

I would never.
..OK, so I do for everything.

🤷‍♂️

[topaz agate]

You can’t make this up lol, I’ve serviced my bearings and the idler stack fell to the floor and has vanished. I am sure I have at least two spares but they’re vanished as well. Guess no more printing today 🤣

[ocean yoke]

I like your second name

[heady solar]

https://tenor.com/view/roasted-oh-shookt-gif-8269968

[ornate jolt]

I got my sendcutsend order today! How are you all cleaning up the edges? Small needle files?

[heady solar]

120 grit sandpaper

[ornate jolt]

Really? 🤔 OK! I’ll give it a shot. Thanks Charlotte.

[wanton shuttle]

i used 120/180/220/500/1000

wet sanded at 1000

[indigo orbit]

i noticed when doing my toorhed idler on my feont mount x joints that rhere is extra space between the printed apacer and the top of rhe joint ahould inuse more shims to take it up or mod the spacer

[shut pewter]

That's common, shim as needed

[indigo orbit]

okay cool

[wanton shuttle]

Noticed something in the FMG cad file for the new 4th bolt mod while referencing measurements.

The belts are 5mm away from the bottom of the x joint plates. the right side is centered on the bearing stack, and idler.

on the left side the bearing stack the belt is centered but the idler it is not centered and is sitting directly on the flange of the idler.

[shut pewter]

I will have to look at this later

[shut pewter]

Just a limitation of placement/space.

[wanton shuttle]

Yeah i figured it was something like that, do you know if gates makes a less tall toothed idler?

[shut pewter]

dont think so

I never had issues

I just made sure they were inside the path, some walk is buit into each part

[wanton shuttle]

That’s cause send cut send doesn’t f your parts up(on purpose it feels like at this point)

[wanton shuttle]

I figured out a solution to the spacing

if the lower belt moves up 0.475 in the cad file and different size spacers and adjustments to the rear printed towers would solve the limitation

[wanton shuttle]

Here is my solution to fixing the belts if you wanna take a look at it, their would be tiny discrepancy in shim heights. Just trying to come up with a solution to less belt walk.

that was just a quick modifcation so some might not be exact but the idea is their

[stuck parrot]

I know its a lot later then i suggested, but life came up.. But the meassurements are :
34mm from heart to heart screws in the hemera.(horizontal) and up and down is also 34mm( square setup)
and distance from heart lowest screw to bottom of nozzle is 22mm

[topaz agate]

yay I found LDO motors with the 8mm shaft, https://www.ebay.de/itm/376464409390

[ornate jolt]

Did you buy them all?

[verbal burrow]

I’m sticking with my 8x55 2504’s until classifieds are in Europe

[broken venture]

I would take classifieds over those unreliable turds

My krakens started failing immediately at max power

Also had a dead internal bearing

[wintry marsh]

I have zero complaints with my classified motors.

They are excellent. Iv heard lots and lots of bad stuff about the krakens.

[ocean yoke]

What is "classified motors"?

[verbal burrow]

Fabreeko X honeybadger Classifieds

[ocean yoke]

Lets ask Thomas from 3DO about that

[verbal burrow]

Once they’re out of beta that’s the plan

[ocean yoke]

too late I already ask

[flint notch]

I just got done putting the belt on and don't have tool to check the tension right now. But it doesn't seem to be very smooth. This is my 1st core xy printer so I'm not sure how smooth it's supposed to move with the belts on.

[delicate river]

No smooth how?

Like you feel binding/racking?

Or just mild resistance

[flint notch]

I feel mild resistance with the belt on. Off I could slide it along the rails a lot smoother.

[shut pewter]

Motors add resistance, this is normal

[flint notch]

Ok now I feel relieved. On to the next steps.

[indigo orbit]

got all my plates in now just waiting for more asa to print 4th bolt parts then can reasymble plates and start building frame

[uneven tendon]

Anyone uses CNC router cut parts or is the recommendation laser cut?

[heady solar]

i use cnc cut

[topaz agate]

Oh no it feels like I am repeating every mistake u do just a year later 🤣

So you burnt yours at 3amps? Those are v2, supposedly running cooler but I am going to use the temperature sensor to monitor how they do

[broken venture]

Yeah, both no longer sound correctly or perform nearly as good as new. One also developed shaft play from a dead bearing.

Then they refused to accept them back for replacements or repairs

Hopefully those do okay, but I will never support devil designs products

[sick meteor]

Can someone point me in the direction of a Mount (preferably CNC) that can take a top mount linear rail to be able to mount a toolhead on the front without moving the rail. I have seen them before in the past but cant find them now. Its like a 360 adapter that has the rail and extrusion inside with mounting holes in the front etc. Hope this makes sense.

I have the FMG coming but need a toolhead and the metal EVA toolhead looks so big and ugly

If it was mate for 3.0 then perhaps but the 2.4 personally speaking while it may be a great toolhead for me is awful looking

[shut pewter]

Just run front mount

[sick meteor]

I cant as I have the lightweight gantry

have it this long time, even bought 2 different ones and both as top mount.

[astral ore]

You could stay top mount and run the vz cnc tool head for zero g

Mellow Alll Metal CNC ZeroG Printhead Bracket For Goliath Crazy Dragon Hotend Sherpa Extruder Mini Mercury Ender 5 S1 3D Printer
https://a.aliexpress.com/_mM5hLbn

[sick meteor]

Does that not make the EVA toolhead?

[astral ore]

The EVA tool head is either the eva2.4 or e34m1 (eva 3 for mercury 1).

https://jon-harper.github.io/E34M1/

Both EVA tool heads are top mount

And they’re printed. Don’t think I’ve ever seen a metal EVA tool head. That would be heavy as hell

[sick meteor]

Yea EVA is not a route I want to go down.

The VZ CNC tool head for zero g is the tool head for vzbot that was adapted for zero g belt path.

[sick meteor]

Ahh I see, that sounds like what I need then. Do you know if it can take the 9mm belts? The main reason I went for the FMG

[astral ore]

Ah. It can’t take 9mm belts.

[sick meteor]

Ah shoot

[astral ore]

Well it can, but you’ll have to replace the front bars with threaded spacers

Which could cause other issues. People run them that way.

[sick meteor]

Hmm... more research required then, I guess im snookered unless I go for a DIY option

[astral ore]

You can take a look through this build log for instance. They run em with knurled spacers on the front and I believe 9mm belts

Nice one, thank you for your help, very much appreciated

[late axle]

Just sanity checking here, did i get everything right?

Please ping me if you reply!

[verbal burrow]

Are you getting extra plates? You have both front and top mount XY joints in there

[late axle]

Yes, thats intentional, i want to be able to switch between top and front mount in case a tool head design comes along i like

[verbal burrow]

👌

give me a while, i also need to like quadrouple check everytime i go to order something lol

[late axle]

it's the most eonomical way to do it, given the high "packing fees" and freight fees these guys charge

[verbal burrow]

Looks good to me atleast

[late axle]

thanks

gonna bang the order in tomorrow

[late axle]

Is there anything i should be aware of considering the material for the standoffs and spacers? Would it cause issues if i mixed aluminium standoffs with stainless steel spacers?

[wintry marsh]

No, the hardware is generally stainless anyways so you'll get galvanic corrosion anyways if it happens, if thats what your worried about.

[late axle]

It was mainly that and different thermal expansion coefficients, but for the latter, I was unsure of if it could have a tangible impact in reality.

I'll just go ahead and mix and match then

Thanks for the reply by the way! 🙂

[late axle]

Ok, so I've got another question, this time regarding the hub pulled live idlers.. Can they be replaced by a 20T 2GT 5mm ID idler? Or will this cause some issues?

Or is it needed to use a de-hubbed pulley as live idler to be able to use the set screws to secure it?

Im making the 9mm version btw.

[shut pewter]

Defeats the point of the live idler

Upgrading to bigger bearings that can handle the tension

[severe glade]

double the bearing = more spin? xD

[late axle]

Thank you! That thought crossed my mind. I wasn't so sure what a "live idler" meant!

But i can see the reasoning behind the design.

[ocean yoke]

I wonder if roller bearing exists in this size

[ornate jolt]

when I am counter sinking these screw holes do I need to make them deep enough for the entire screw head to be flush with the top of the piece of aluminum or should they stick out a little bit so there’s more meat for the head to push against?

basically, I’m five and I don’t know what I’m doing. Help.

[broken venture]

I would highly recommend you do slightly deeper

Having the head poke out will cause your plate to slightly warp from getting screwed down

[shut pewter]

Depends on the location

All bottom plates, and the top stepper plates need to be just under flush.

[ornate jolt]

OK. Thank you both. I will make them a little deeper.

[lavish sinew]

@shut pewter any new changes to the stl files?

I saw they were update 2 months ago

[shut pewter]

Mainly just the stepper towers, but those also need the new plates

[lavish sinew]

damn I still have the old ones

[shut pewter]

Not worth changing really

[lavish sinew]

hmm I need to look if I have those old files

[verbal burrow]

they’re still on the main branch if u need them I think

V2 is the new ones

[fading pine]

for the 9mm BOM, should the M3x30 and M3x40 standoffs be threaded? I'm having trouble finding non-threaded ones

same question for the M3x10 and M5x40 Spacers

[shut pewter]

You're getting the kit from my, that's included

[fading pine]

awesome 🙂

[fading pine]

is 6m enough for the 9mm belt (total length, so 3m per)?

[verbal burrow]

Which printer? Pro or plus

I think even 5 meter is enough for both of them, I vought 2x 2.4 meter belts

[fading pine]

oh, plus

[shut pewter]

yeah 5m is enough

[ancient lichen]

Do you still have more kits available?

[shut pewter]

Yeah just dm me. There is a bit of a lead time, still getting parts finished and sorted

[late axle]

I didn't know there was a kit.. Would have gotten that instead of self sourcing had i known lol

[verbal burrow]

turtle has them sometimes but then there’s also shipping to EU, etc

It’s really nice just getting all the hardware included

[late axle]

Saves a lot of time. And mistakes i did, like ordering the optional 8x x-joint spacers in 3mm as opposed to 5mm..

[shut pewter]

Yeah I don't always have them, and wasn't doing them for almost a year due to lack of time. Then it took me like 6 months to push the update

And didn't want to send the old rev out before that was done

[late axle]

Understandable!

[ancient lichen]

Ok pmd

[fleet siren]

is there a 4wd version of this gantry system?

[verbal burrow]

Theres no AWD config for the FMG mod

[fleet siren]

whats fmg?

[verbal burrow]

Nor for the stock mercury motion system, you'd need to venture into user mods

[fleet siren]

i thought fmg just meat front mounted

[verbal burrow]

full metal gantry

[fleet siren]

ahh
