[radiant ether]

Wonder if i should use sus bearings or sus drylins

[radiant ether]

wait. why do I care where the bolt holes are on the printer

I can just drill more holes and mount things wherever i want

[radiant ether]

rough sketch of the idex gantry

gonna put the tensioner on the toolhead to make my life easier

I could also keep the stock tensioner

[radiant ether]

switching to markforged

[radiant ether]

added up the running costs so far and im $670 down on this printer 😭

the little things add up quick

[small aspen]

Neat

[radiant ether]

im gonna add berd air cooling

so I can print lower temp stuff like ABS

[radiant ether]

😁

[small aspen]

Mad lad

[radiant ether]

Bed is here

[wraith bloom]

Looks preem

[daring quarry]

I love the juxtaposition of shredded brass and perfectly milled bed

[radiant ether]

i wonder how you're supposed to do berd ducts

[fluid ravine]

people in the past got a bit of brass tube, crimped and soldered one end shut then bend it round to go around the nozzle and drilled some holes

[radiant ether]

I've seen ppl bolt the end shut

[fluid ravine]

will work too

but crimping and soldering tends to be more space efficent

[radiant ether]

Mhmm

[fluid ravine]

in your case it doesnt really matter tbh

[radiant ether]

Yeah. I got space in front

[fluid ravine]

with a round duct its more of a concern

to get that 360° coverage

[radiant ether]

Should I do a round duct?

This one seems fine

[fluid ravine]

will work

would design the mounting for the tubes in a way that you can rotate them to fine tune the outlet angle

[radiant ether]

I plan to friction fit+grub screw

[fluid ravine]

should work

[radiant ether]

I should also leave enough space for a nozzle wrench

[fluid ravine]

did a hybrid duct ages ago that was just a friction fit. but it was for a machine that wont manage to go past 100mm/s

yea thats usually a aftertough for a lot of people

[radiant ether]

Honestly I probably won't go fast but it should actually be pretty speedy

[fluid ravine]

would also print a jig for drilling the holes, free handing it can work but is annoying since its a round surface and a centerpunch might close the bore to much

[radiant ether]

Oh yeah. I might go do it on a drill press tbh

Seems like a pain

[fluid ravine]

did it on a drillpress too but freehanded it

was not great

a jig that holds the tube in place with guide holes for the drill helps a lot

did used thin walled aluminium tube

[radiant ether]

But the tube comes pretty long so I'll probably try going at it with a cordless

[radiant ether]

I'm planning to use brass

3mm id 4mm od

[fluid ravine]

ive got the tube for cheap so ive used it
brass will be fine too

[wraith bloom]

Yellow brass (the one that cuts easily) can easily crack while bending, so be careful and anneal often

[warm thunder]

Scraping your bed when?

[radiant ether]

Stilts installed

[radiant ether]

Surely this isn't gonna be an issue

Wait. Now that I've got the stilts on it actually clears the heatsink

[royal moss]

you happen to get more than one bed?

[radiant ether]

for the heater fan

@wraith bloom I can just parallel the two 24v 5a on the flexpower toget 24v 10a right?

[royal moss]

no lol i was asking if you bought more than one bed plate so i could buy the second one lol

[radiant ether]

oh no. why would i do that

just buy direct from midwest steel supply

if you wanna high temp you have to at least have the bed and hotend for it

[royal moss]

oh

how much was it

[radiant ether]

almost 60 with shipping

and another 6 for the heater

[royal moss]

not bad at all

[radiant ether]

you gotta drill and tap it yourself tho

[royal moss]

they come with the holes and stuff?

[radiant ether]

no

[royal moss]

ah

you have a .step for it? i’m curious how much jlc would quote me

[radiant ether]

not with the holes tapped in the step

[royal moss]

thats fine

[royal moss]

ty ty

[radiant ether]

I dont think they have cast alu

just gonna put this here so I dont lose it

[radiant ether]

Don't have the crimps for it but probably good enough

Maybe I should creality all over it

Crimped jst ph onto a wire and heatshrinked on top

It holds on a lot better than DuPont

[wraith bloom]

I'd need to read the datasheet

[radiant ether]

The manual said it's ok 👍

[radiant ether]

the picture above mine is from armchair and idk why they have pin 2 connected

so im just connecting pin 4 only

https://www.xppower.com/storage/portals/0/pdfs/SF_fleXPower.pdf

[wraith bloom]

Ah, nice

[radiant ether]

oh yeah. the ssr says earth the mounting rail, and the psu chassis/shell is earthed, so it shouldnt be toooo bad to mount the relay onto the side of the psu right?

[wraith bloom]

Does PSU chassis heat up?

[radiant ether]

it actually stays really cool

big fan blowing through it

but at that time I was only pulling ~300w

actually, this shouldnt be that far off either. 150 chamber, 160 hotends, 30 fan,

[wraith bloom]

Then maybe

[daring quarry]

Could use headless bolts

[radiant ether]

Good idea

[radiant ether]

All the filament is here

[median eagle]

Oh its still inside the cartridges? You need a can opener?

[radiant ether]

I'm just gonna keep it in the box and pull from it out the front hole

To respool and dry

[warm thunder]

There is a way to do it, look up the datasheet of the flexpower, there are like 4 wires you need to plug in IIRC

[radiant ether]

@warm thunder Only one wire apparently

[warm thunder]

On mine I need to link 4 or 5 wires I think

[radiant ether]

Huh. Interesting

Maybe I'll email them just in case I'm missing something

[radiant ether]

gonna pray that it holds

I really dont see why it wouldnt hold

[radiant ether]

did a spool carousel for the air fryer

Time to drill some holes now

[radiant ether]

Works like a charm

[mortal portal]

pimp my fryer

[radiant ether]

the whole process was surprisingly painless

I even had an m10 tap that I didnt know about

[median eagle]

👉 👈 gib file, many thanks?🙏

[radiant ether]

oh right

[radiant ether]

the cylinder looking thing is printed in vase mode

15g in total of filament

surprisingly light

[median eagle]

okay bolt down bearing block add plate with bolted in cylinder to hold the spool?

[radiant ether]

yep

[radiant ether]

you might have to 3d builder your way aroud to get the holes to fit with your fryer basket

for bolting it down

[median eagle]

you know me too well 😄

[radiant ether]

id also print a few sizes of the vase mode one. the closer it is to your spool inner diameter the better it is

and if you use the spool clamp, here's the tiny one

[median eagle]

I'll see how much headroom I have and might add a threaded rod and conical clamp

[radiant ether]

one cool unintended feature. when you tighten the bolt on the top too much, it causes the nut to expand the print on the bottom, grabbing onto the bearing

this is nice bc the bearing now comes out with the spinning plate, so you can take the bearing out of the fryer for when you are annealing or regular drying

[radiant ether]

update post pic

[median eagle]

I'll hereby suggest the name "Master Blaster"

Also print a decorative turbine shroud

[hazy finch]

Looks like the same airfryer I am using for annealing

Just bigger, mine doesnt fit a spool

[radiant ether]

from the original 750rpm to 7000. at this point I will probably eliminate the berd air cooling for the time being

[radiant ether]

came free with my previous apartment. it's kinda bad and the door gets easily stuck when trying to put the basket in, but it is big and VERY quiet

almost like it was made for drying

[hazy finch]

I was about to buy one but then I found it in the basement I had no idea it was there

This

Its pretty quiet yes, does what I need it to do

[radiant ether]

you should take the coil to make a filament dryer lol

[hazy finch]

Already have a commercial drier, no need

The coil in mine doesnt look like that tho

Its round like this

[radiant ether]

first one seems a lot more stable but second one with loong bolt should also be not bad

[radiant ether]

@wraith bloom what do you think about using this stuff to stick the heater onto my bed and to bond some g14 to springsteel

it's not too expensive and a lot less messy than RTV

https://cshyde.com/item/ication-specific-optically-clear-transparent-tapes/silicone-transfer-adhesive/trs-silicone-adhesive-12x12

[wraith bloom]

How hot are you planning to run it?

[radiant ether]

at least 180 and no more than 230

afaik 230 is what I want for PPSF but im not gonna go there if it makes things hard

[wraith bloom]

Honestly, I don't know. 3M gives their silicone transfer tape 260C short term and only 90C long term

For 3M 91022 silicone transfer tape

[radiant ether]

im probably just gonna buy a thicker build plate and go with the RTV then

[radiant ether]

thanks btw 🙏

[wraith bloom]

Thanks for bringing to my attention that these exist

[radiant ether]

We're getting there

[radiant ether]

Should I leave the mouse bites in or sand it down somehow

[median eagle]

If it works why bother🤷 unless you don't like the looks of it of course

[radiant ether]

I dont hate it. ill leave it in

adds a certain charm

[mortal portal]

looks fine

if you want to be pro about it add an edge rubber seal

less effort and looks nice

[radiant ether]

good idea

duct tape is close enough right?

actually, ill be covering everything in alu tape anyways

[warm thunder]

Duct tape is always the solution

[royal moss]

getting it from jlc?

[radiant ether]

Lmao TL I literally found the drawing on ali

[median eagle]

Whats up with the ball bearing looking thing on the side?

[wraith bloom]

Likely a press fit plug, from how it was manufactured

And yes, balls are used because they're very easy to press fit into various diameters

[median eagle]

Makes sense

So they made a U by drilling a π and plugging the ends?

[wraith bloom]

Well, usually you'd plug one end, just make the hole blind

[median eagle]

Makes more sense yes but I didn't have a symbol ready

[wraith bloom]

TI → ∏

[radiant ether]

AAAAAAAA

[median eagle]

What did you do?

[radiant ether]

I accidentally clicked save when tuning pressure advance so my slicer got all fucked up

And wasted a lot of filament trying to troubleshoot

[vale narwhal]

is the heat from the blower going to be a problem for the belts in the chamber?

[radiant ether]

Preem

[daring hound]

https://tenor.com/view/cyberpunk-edgerunners-cyberpunk-studio-trigger-netflix-cd-projekt-red-gif-25713013

[radiant ether]

I don't need part cooling anymore

[daring hound]

Just to maintain temp you’re gonna be running max heater fan the whole time

[radiant ether]

Now I just gotta find a way to control it. It starts spinning as soon as I plug it in for some reason, even when I have the fan turned off

Guess I need to high side switch this too 😭😭😭

[mortal portal]

now you're cooking

[median eagle]

Its also looks like a very effective finger chopper

[radiant ether]

that's where the cover comes in

[daring hound]

But my fingers crave the blade

[median eagle]

So you can funnel stuff into the blade, got it

[radiant ether]

Ah dammit. Gotta redo the gantry CAD

There's things in the way

[radiant ether]

well I guess im doing a complete gantry overhaul

[noble aspen]

Can the plastic handle the temps

[radiant ether]

yes

apparantly PPS-CF is good enough

[noble aspen]

I meant the clear plastic

[radiant ether]

ah yeah, i honestly dont think itll survive but mr sanchez already did this and he just put foil tape on it and it was fine

[noble aspen]

Huh, neat

[radiant ether]

hmmm this does make it more compact

we just copying the 22idex now huh 😭

[royal moss]

this is sick

[radiant ether]

and the belts are also pulling on COM now too

[median eagle]

22IDEX V.kevin

[radiant ether]

having some trouble with the xy joints

but so far so good

[radiant ether]

all that's left to do is the toolhead

[radiant ether]

So the plug on these motors aren't rated to above 100c. Do I just solder fep or silicone wire to here or do y'all think the JST will be fine in 140c

[median eagle]

considering PEEK Performance was fine at 147°C for extended times.....probs fine for a few prints?

but if you have it already open....

[wraith bloom]

Gonna have a strain relief for the wire?

[radiant ether]

sure i can add that

but im definately gonna have to redo the wire on my leadshine with PVC insulation right?

[wraith bloom]

Yep

[wraith bloom]

You'll need to add it because solder barely holds at these temps

[radiant ether]

Oh boy. Guess I'm not using the leadshines

[median eagle]

just strip it completeley and put glass fiber sleeves over it

[wraith bloom]

That's problematic

[median eagle]

hence the crossing out

[radiant ether]

guess there's only one thing left to do. watercool the wires

I could try using these funny mineba motors

[radiant ether]

Hard to see but the parts fit

[radiant ether]

Respooled my 9085 in annealed PET-CF

[noble aspen]

heyyyy Kevin

what chamber temps are you going for

and are the motors in the chamber

@radiant ether

[radiant ether]

140 chamber and yes

Watercooled

[noble aspen]

oh interesting aight

makes sense

[elfin lark]

I gotta show the guys in printsleo server this

[radiant ether]

Time to do unspeakable things 🙈

[wraith bloom]

Give them a shim or they might pinch your belts

[mortal portal]

that's screwed up

[snow vine]

those need a 0.5mm shim inbetween the bearings

[radiant ether]

I know it needs shims. this was just for laughs

[snow vine]

oh

[radiant ether]

I even have it modeled into the bearing stack in my CAD

[royal moss]

whats the space in the part you left for these like?

9mm?

[radiant ether]

wdym?

[royal moss]

like how big is the gap between the top of the printed part and the bottom?

i forgot to add the spacer lol

[radiant ether]

Id leave 1mm on each side and put 0.5mm washers on each side

[royal moss]

so 8 + 1 + 1 + .5 + .5?

[radiant ether]

9+1+1=11

[royal moss]

same number

[radiant ether]

gonna be switching from beacon to klicky00 buckshot

what the hell do I do with the beacon now 😭

[wraith bloom]

Put on a HDT test jig for distance measurement

[radiant ether]

hmmmmmmm

yes

hmmm I have ~10mm left at the back

I can put up some insulation to seperate the motors from chamber

[wraith bloom]

[radiant ether]

accidentally did 30mm spacing instead of 31mm on the motor mount

how the hell did I even get the bolts on when doing the test fit 🤔

oooh i only put in one bolt 🤣

[wraith bloom]

Well, it was good enough for testing

[elfin lark]

Once this is done we just wait for the amazing plus4 IDEX HT

[royal moss]

what size are these bearings?

[radiant ether]

f623

[royal moss]

ty

[radiant ether]

debating what I should do for Z probe and nozzle wiping/blocking

[radiant ether]

I think im gonna do a purge bucket kinda thing with a silicone/ptfe wiper on the edge

[radiant ether]

something like this

[noble aspen]

doesnt annex do smth like this on the k3

[fluid ravine]

It takes quite some space, cant run the purge bucket on my k3 because the mrw bed is slightly wider

[radiant ether]

Yeah, seems overly complex to me

[fluid ravine]

its a bit of a system
it uses the magnets for the Quickdraw to lift the arm of the wiper towards the nozzle
probably to make sure it goesnt get hit during a print

[radiant ether]
