Copy, thanks!

surreal storm
#

For 9mm belts or are you still running 6mm?

surreal storm
#

Same for the 9mm, I am going to see if I can get these 6mm inserts into Fusion and add the ring for the bearing until something official is released.

lucid citrus
#

He is doing the 8x55mm shafts like I did.

#

So different bearing mod

lucid citrus
#

ahh

#

I am not sure if the 3004 shafts are long enough for a support bearing with 9mm belts

#

6mm probably

#

but 9, not sure

surreal storm
#

I am not a Pro with trying to get these meshes into solids, it would be nice to have a step of the RevB if not I will have to use the Step of the RevA that is provided.

lucid citrus
#

I'll try to push those next weekend

#

The new printed inserts

#

I didn't push the cad with the stl files yet

surreal storm
#

Thanks Turtle.

lucid citrus
#

The only cad I did this weekend was a cable tie mount. Been slowly wiring up the toolhead today. Need to do a few more things before the rest of my parts show up to run the belts later this week.

Exciting times, I Think I am going to place my order for the bata frame sometime this week. After going over my printer yesterday, and finding all the broken stuff, I have been printing replacements of the replacement parts all day today. I changed out the 2209 for 5160's and it doing very well.

I also put in 15k steps today

#

I finally setup 2240s that I have had for like a year lol

#

For z and e

#

5160 watterots for xy

#

How so? Everything I have heard is they are the best 5160 stepstick

#

Externals are better for pushing the limits now

#

Just have to order them direct

#

And solder them, not that hard

#

From what I heard they do not need cooling

#

I'll still hit them with fans

Yup

broken phoenix
#

Actually looks like Fabreeko carries them too

#

I do have an octopus pro. 🤔

lucid citrus
#

Does he have them in stock again?

broken phoenix
#

Probably want him to confirm. Pricing is spot on as well.

lucid citrus
#

If the site says they are in stock then should be good

#

I had to push him to get those awhile ago and last I looked they were out of stock.

#

So looks like he ordered more since I last looked

broken phoenix
#

Better hop on it. I've used Watterott drivers before, seemed to be great quality.

lucid citrus
#

You cannot but heat stinks on them by the way

#

But they also do not need them from what I have read

#

The driver faces down

broken phoenix
#

Correct, and no added thermal conduction to the top for a heat sink. Depending on the board you might be able to pass air under the driver with fan.

#

I'm really curious how warm they get at full tilt and no heat sink

sweeeet, thanks @radiant hound and @spiral ibex

So if you run close to 200hz or higher, you might need to modify the M3 holes between the dowel pins for a 4th M5 through bolt. @blazing trench managed to start to bend his towers running a higher tension.

#

I'll probably add a set of DXF files for high tension builds with that converted to a m5 hole.

vale kettle
#

huh

#

good to know

#

it bends even with a standoff in there?

vale kettle
#

Ah I follow

indigo halo
#

That extra anchor point would be helpful on the printed stepper towers too. They need it more than metal parts.

lucid citrus
#

no room on the stock frame

forest ridge
lucid citrus
#

I have zero plans to add support like that for the stock frame. This mod will work fine on the beta frame though.

forest ridge
#

@lucid citrus what aluminium do you use for this stuff and the x joints?

vale kettle
#

7075

#

Though I imagine you could go to 6082 or 6063 with minimal loss in integrity if those are more available

#

I have no plans for awd mounts myself as I am not willing to give up travel and need anything I design to fit the enclosure.

forest ridge
#

Maybe if you or someone willing to design something like this, made the leadscrews shorter you could put the motors under the y 2020 so you could make the main body of the stepper towers slimmer so that they dont interfere with the toolhead movement

lucid citrus
#

I also do not think awd is needed, to many people look for solutions to problems before building anything because they saw someone else do it.

#

But I mainly design parts I want myself, and try to make them work for other configurations that others would need within reason

forest ridge
#

I totaly understand that, I just shared my thoughts and thought somebody would gind it useful

lucid citrus

Mad prophet did a awd remix

# lucid citrus Mad prophet did a awd remix

That is unproven as yet and like Turtle I want to ensure everything works well before I hand it over to the community.. If I measured right none or very little print volume should be lost on a pro.

#

But I don't own a pro so I'm relying on the step file..

# spiral ibex you will lose travel though

Only if I measured wrong, at least not for those that are using an eva 2.4.. I took the gantry to the zero position in Y ei; nozzle at the edge of the bed and then used that position to measure the distance the x-joints where from the front of the printer and used that dimension as my limit.. You may lose a tiny bit of x travel at that zero position to the end of the AWD mount, but not in Y. I redesigned the entire mount so it would minimize travel loss on a pro (was never really an issue on the plus) but those who don't want that can keep the stock motion system..

I suppose those are 608s bearings?
If so, what was the size of the cutout you have in the plates?
(or rather do I need tolerances for aluminium or can I go snug?)
(and also could you provide the cad files for the rev-B printed parts as I want to add bearings to my bottom plate and need to modify the printed insert to leave room for the screw heads securing the bearing, I would obviously be eternally grateful :))

#

@lucid citrus whats the differents between the imperial and the metric?

lucid citrus
#

Base material thickness

#

Imperial is for 3.175mm thick plates or 1/8 inch.

shadow creek
#

i got the first batch i need to messure that then i think

shadow creek
#

😂

woven dome
#

Ya. USA does imperial. Because we are stubborn 🤣

spiral ibex
#

If you're talkin about the batch that I ordered thats all metric.

#

It's near impossible to get imperial here lol

woven dome
#

Ya.

#

@lucid citrus I suppose you haven't had time to export the newer printed parts of the metal towers as cad files?
If so what were the changes you made (except for the window) cause I want to add a bearing for double shear support

lucid citrus
#

Just the window

blissful pine
#

ah nice
I can do that myself, thx <3

lucid citrus
#

Yup

blissful pine
#

does the original pulley alignment tool fit the imeprial or metric plates?

lucid citrus
#

I don't use that

#

On any of my builds

blissful pine
#

well

forest ridge
#

what do u use instead?

lucid citrus
#

I just line them up with the belt? Run the printer and adjust it needed.

#

Having the window let's see if it's tracking in the center or not

radiant hound
#

I usually just put everything in place with loose pulleys, move the toolhead around and it gets in the right place by itself then I tighten it

#

Kept on printing the top and bottom inner inserts and the measurements were all wrong, turns out I hadn't ran a Z-tilt in awhile, lol.

#

Right under 35mm for both sides now, hopefully doing a rebuild of my Merc in the next couple weeks to install them plus a bunch of other goodies.

#

Yeah, I should just add that to my start print macro.

#

@lucid citrus what bearings do you use for bearing support?

blissful pine

#

which one do i use 12 or 8mm?

#

thanks, didnt want to bother you directly

#

It's not completely

#

Some might only want to start with the steppers

ionic patio
#

Well it's part of the Full Metal Gantry

lucid citrus
#

These files work with the rest of the printed files

#

Same, but not in a way

woven dome
#

You doing kits? Like to have them matching my steppers. 😁

#

I'll want to upgrade to something like the Xol or Archetype toolhead for 9mm belts if I ever get there.

shadow creek
#

@lucid citrus in the docs are standing in the bottom m3x16 but also m3x8 what must i use for the bottom part

lucid citrus
#

M3x12s

#

16 isn't listed any where

shadow creek
#

sorry 12

#

thnx😊

#

@lucid citrus did you switch the final version of this to GitHub? Or am I just not seeing them

lucid citrus
#

What do you mean

#

This project and my full metal gantry have only ever been on github

rich elm
# lucid citrus What do you mean

I wanted to research doing this on my Beta frame since I’m not in a rush.

Ok. I didn’t realize that. Easiest way to find them?

lucid citrus
#

Should be be pinned in here

#

Or maybe I forgot

#

On my phone walking my dog, then off to work

rich elm
#

Thank you I found it. I’m new to discord and forget about pins.

lucid citrus

The full metal gantry has the github pinned
