🖨 3D printing

[grizzled girder]

Yea dont be breathing that

Send it out the window. Don't need fancy filtration unless you are 24/7/365 printing ABS and other stuff you prolly shouldn't breathe (even PLA if day in day out)

Huh... lemme look

[ember gulch]

literally the only time we or my school have used abs was for a wall mount for the ams since we didn't have a place to put it (and we wanted access to above the printer)

and it was some really old MakerBot abs that needed like 10 mm brims because it kept warping but i eventually fixed it

that's the only time ive touched abs and it'll probably be that way for a while

[grizzled girder]

Yea we mostly print PLA for prototyping then final parts get made in ABS or nylon

Occasionally a fancy filament

[ember gulch]

dont know a lot about nylon besides it being very fucking hard to print or something

[grizzled girder]

A breeze to print on x1c

[ember gulch]

filament blends and other types of filament are a weird area for me

[grizzled girder]

It likes to warp sometimes. Just gotta get temps right and good plate adhesion

I'm a big glue stick guy

Yea huh. I think it's used to be guaranteed what plate you got...

Honestly I have both and I enjoy printing on the cool plate more. Cleanup is easier, still awesome adhesion every time

For PLA

Pei gives it this nice feeling/looking texture on the bottom tho

[ember gulch]

i prefer the pei more over the cool plate but if i get the cool plate then it's fine

i found this really cool print that you put under the ams and it stores the plates

it can take up to like 8 so that's nice

https://makerworld.com/en/models/1227809-fnt-ams-plates-holder-for-x1-p1-plates-button-slim?from=search#profileId-1360514

[grizzled girder]

Ok that is pretty damn cool

[late trench]

Building new parts, airtac lrm rails, ldo space grey frame, asa monolith parts

shit is FRESH

Gotta get some SLM printed parts for this A4T toolhead though, the belt tensions are so high that it would destroy it

bed needs transferring onto new parts though

[empty otter]

tested out TPU paremeters tiday

learned that under temp is not ideal

learned that over temp is ideal (5 degrees more than default)

learned that more retract distance is super ideal

[late trench]

make sure its dry too

otherwise it can mess it all up

[ember gulch]

JUNE 19 MY ASS

very exicted

[ember gulch]

ok so idk why but they don't ship the ams with the printer like they used to

i think its because i have the AMS 2 pro

aka i need to wait until June 19 for it

and June 20 for the extra spools since the box only came with one

but the exterior spool holder will do fine for now

[ember gulch]

need to find a model that redirects the waste chute to the right of the printer and off my wardrobe

i have a bin that ill just let all the waste fly into on the floor but i need to have the model not block the exhaust port

[grizzled girder]

Um. Design one

😁

U bought a 3d printer for goodness sake

[ember gulch]

im awful at designing thats the thing 😭

i found some models already but like

i cant tell if itll be in the way of the exhaust

(i need the exhaust to be exposed for a vent pipe attachment

[grizzled girder]

learn!

people here can def help with the process too

(like me 😅)

and its not hard, trust me

[ember gulch]

i would but i dont have the time atm

i have a course i have to do for school and i have to do a bunch of irl shit

maybe when i have the time

[empty otter]

remember roblox studio is a 3d modeling software

ive exported my reactor and printed it before

[ember gulch]

first print and to no ones suprise it came out perfectly

well almost perfectly the supports were a bit of a pain in the ass but what do you expect with material on material its going to fuse a little
i just need to increase the roof distance

but everything else was perfectly fine

[late trench]

yea it produces a lot of waste

[late trench]

nah bambu is good

im currently building this motherfucker

stuff is loose rn just test fitting

it's designed for high belt tensions so the motors need double shear
these are regular shaft size motors so i have to mount them like that lol

basically it'll go nuts with speed/accel/scv but ill probs just run regular speeds

also i have multiple worn linear rails that'll be repurposed into extrusion backers to combat bimetallic thermal expansion
they're stainless steel so they work

[grizzled girder]

Huh? Wdym

[late trench]

they're a genuinely good printer brand so i can't blame anyone for buying them

[ember gulch]

im well aware lol

[late trench]

ok

[grizzled girder]

What does that have to do with that I said?

[late trench]

"u bought a 3d printer for goodness sakes"

[grizzled girder]

I guess im just confuses lol

[grizzled girder]

Yea. That was in reference to the fact that kade was looking for a design instead of designing one themselves

[late trench]

[grizzled girder]

I'm confused bruh

[late trench]

🐟

oh well

not a big issue don't worry

[grizzled girder]

Wait no wdym

[late trench]

basically i was like, you can say buying a 3d printer is not the best option, but im saying bambus are genuinely good 3d printers that even i would use lolol

so can't judge

[grizzled girder]

Wait did I use that phrase wrong? I mean like "you bought a 3dp for goodness sake [and aren't gonna design a part yourself?]"

Nothing to do with bambu or the brand

[late trench]

yeah i know but I'm just saying bambus are just too good, can't blame you if you buy it

let's just move on 🐟

[grizzled girder]

LOL ok im just confused man

I'm tryna understand what u meant

[late trench]

oh well lolol

ive got to build this printer frame now

ive got to work on this one afterwards and im not looking forward lol

[grizzled girder]

But fwiw, love bambu and their printers. If you dont care about tinkering with your printer and want something thats the best bang for your buck and will be rock solid churning out prints 24/7 then they are the best choice rn

[grizzled girder]

Scissors in the electronics bin 😨

[late trench]

yeah the wires are scrap and it's just full of motors
plus i didn't actually put it there to begin with 🤣

cba atp

[late trench]

real

[grizzled girder]

I've never had a print fail on me on the many bambu printers I've used

[late trench]

they are nice

[grizzled girder]

And never had to level any beds 😄

[grizzled girder]

I wonder if BLDCs are ever gonna get to the point where they are worth using over steppers

[late trench]

not sure what their torque is like, maybe geared at least

test fitting this shiz more

still need some slm parts because the belt tension will make it explode probably

[grizzled girder]

Honestly I think modern BLDCs are comparable in stall torque

To steppers

[late trench]

eh i don't know much about them

AC servos are nicer than steppers

[grizzled girder]

They're just harder to control precisely

AC?

Those exist??

[late trench]

yes, high performance printers use AC servos for more power and speed

[grizzled girder]

Oh they're fat

I was thinking small servo

[late trench]

https://youtu.be/ksZEaQ7y_Tg?si=ZuXry5NclDThC8QD

[grizzled girder]

Imagining that + an inverter lol

[grizzled girder]

Oh ok

[late trench]

ok gtg for now

sorry but nice talking

[ember gulch]

i just dont have the time to learn good modeling 😭

[late trench]

Hours later I'm still squaring the frame

It has to be perfectly sqaure

The rails are airtac rails which are very good quality but also means there's little tolerance for position deviations

Otherwise it'll bind to fuck

[late trench]

put some parts on to test again

[late trench]

soz for pic spam

[grizzled girder]

nah no worries I was just making a point

whenever you feel like learning tho: give it a shot

[grizzled girder]

how are u always building a 3d printer

how many have u built

[late trench]

🐟

this is a rebuild of my orange one

[grizzled girder]

oh ok

[late trench]

this one is heavily modified from the stock design

so yeaaaa

[grizzled girder]

so is the stock design a voron? idrk anything about the custom 3d printer space

[late trench]

high belt tensions, more rigid, yea

[late trench]

yes

[grizzled girder]

ok

[late trench]

this has a different motion system

[grizzled girder]

those are the de-facto designs I've seen

not core xy?

[late trench]

yes its core xy

[grizzled girder]

wdym different motion esystem

[late trench]

https://github.com/VoronDesign/Voron-Trident this is stock design

the motion system, so motor mounts, front idlers, y carriage joints, etc, are redesigned for high belt tensions

[grizzled girder]

corexy is cursed btw I never actually understood how cursed it was until I looked into whats going on with the belts

[late trench]

wait until you see corexz

just corexy but vertical 🤣

[grizzled girder]

oh dear

why would you want that 😭

isn't there much more head movement on xy plane

I guess you wouldn't want it, thats why corexy caught on

and not corexz

[late trench]

this is my corexz printer

funnily enough it used to be an ender 3

it's good because it's tighter fitting, meaning i can bolt panels on the frame as an enclosure

[grizzled girder]

huh

nice

what do u print usually?

[late trench]

literally just printer parts and tools

i like to design them

[grizzled girder]

no way bruh

this guy prints printers on his printers

[late trench]

yez

[grizzled girder]

self fulfilling hobby

[late trench]

yeez

[grizzled girder]

ok u do u man

[late trench]

i often print ASA instead of usual PLA so I need hot enclosures and all

[grizzled girder]

I will just keep buying printers 😁

[late trench]

i often used this one for even more demanding plastics because it had active heating installed

[grizzled girder]

lol we had to print some parts out of nylon cuz we were melting/deforming the pla under the temps

ok thats very vague

they were pulleys

[late trench]

once this printer gets finished i'm reprinting the parts out of abs carbon fibre

[late trench]

yeah nylon errrrrr its good but it likes to "creep"

depending on nylon type

[grizzled girder]

apparently someone screwed up and there ended up being a lot more friction in the system

[late trench]

like it'll deform veeery slowly

[grizzled girder]

between the belts + pulley teeth

[late trench]

yeaa thas bad

will cause print artifacts like VFA's

[grizzled girder]

so the pla pulley had 0 teeth when we inspected it

cuz we melted it all

and smoothed it

[late trench]

[grizzled girder]

oh huh

oh well

[late trench]

under heat***

[grizzled girder]

the pulleys are in service for a very short life

I think it was cf reinforced nylon

[late trench]

pa6 or pa12?

or just generic

idk

[grizzled girder]

I think it was pa6

actually no clue

[late trench]

pa-cf is nice but yeah we don't use them because although they'll withstand usual heat they like to creep so yea

[grizzled girder]

I didn't purchase it

it liked to warp on the bed actually

iirc

prolly cuz whoever printed used hair spray and not glue, oh well

[late trench]

yes you have to have an enclosed chamber because ambient air is too cold for it

and itll shrink and pull up on the bed

[grizzled girder]

we had

all printed on a p1s

[late trench]

p1s with enclosure i assume

[grizzled girder]

they sell p1s without enclosure?

oh yea they do

yes with enclosure

[late trench]

p1s is standard without enclsoure

[grizzled girder]

I wonder if I can find a photo

[late trench]

i don't like hair spray or glue

textured pei is very good if kept clean
and i often use vm nano adhesive if really needed

[grizzled girder]

pei is good for pla and lower temp prints I think

idt it works well for higher temps

welcome to correct me tho

[late trench]

it kinda depends

and type of pei

[grizzled girder]

yeah probably

pla on pei is awesome tho

no adhesive

[late trench]

there is textured pei, which is a thin layer of pei on a textured metal plate
and then there is smooth pei, which is an adhesive layer that goes on top of a plate

if your chamber temps are bad, the parts will pull up on the smooth pei and destroy it
textured pei is usually one with the plate so doesn't really happen

it kinda depends on what works with your printer

[grizzled girder]

Lol I found this picture instead

[late trench]

i used textured pei for everything. if i get anything as little as a fingerprint i take it out and scrub it until it's clean. it's god tier

[grizzled girder]

oh I didn't even know theres a smooth pei plate?

[late trench]

ye

it's an adhesive backed pei film

[grizzled girder]

oh huh

[late trench]

stuck onto a spring steel plate

[grizzled girder]

I've only seen the textured ones

[late trench]

thats why if your parts warp and they stick, it'll literally pull the pei up

[grizzled girder]

they make the bottom side of the part nice feeling

[late trench]

ye its good

[late trench]

oh no who last handled the damn spool

it's often 99% user error

when that happens

"never let go of the end of the spool"

[grizzled girder]

ye it was user error

thats why I took a photo

[late trench]

ah right lolol

[grizzled girder]

sent it to the slack 😭

[late trench]

i just have to clarify it because uh

people bash manufacturers often in 3dp discords

and im just too used to it lmao

[grizzled girder]

Lol I found this too. Good memories. (Someone forgot to install the screws)

[late trench]

Found a pic of the* original design

[grizzled girder]

ignore the terrible print quality

[late trench]

Hell

[grizzled girder]

I think we were time crunched, so the printer was set to like

super speed

ludicrous speed

[late trench]

chains 👁️

[grizzled girder]

also it was printed flat for strength instead of looks

last time it split on a layer when we printed it the other way

[late trench]

Lmao I say if a mechanical part works but looks awful

Then just ignore it

🤣

"if it fits it sits"

[grizzled girder]

it split like this prior

so we printed with layers the other way

lol

[late trench]

Do you use bambu ams

[grizzled girder]

we didn't own one at the time

I think they have one now

[late trench]

I kinda want to get into multi colour but it creates a ton of waste

[grizzled girder]

well, single extruder lol

purging and then backout takes a long time

we don't really care much about color cuz we mostly make functional parts

ams is nice just to put diff materials in and leave it there

so you can print without human having to back out the existing

and swap

[late trench]

oh i do like that feature

i was thinking of building a "box turtle" which is sorta like an open source ams themed on voron

but it costs a lot

[grizzled girder]

oh that looks awesome

and expensive

lol

[late trench]

yeaaaa

these are cheaper but no spool holders

these are quite smart
think of like the filament channels being built as half extruders
the top mechanism can move across lanes and completes it into a functional extruder that can push the desired filament into the printer extruder

[grizzled girder]

Here's where those pulleys I was talking abt went

[late trench]

Wtf is that

Some sorta battle bot thing

[grizzled girder]

ye its a highschool robotics competition that I was a part of 2 years ago

its decently big in the US

[late trench]

you're doing that in highschool god damn

[grizzled girder]

theres a few teams from the UK too I think

but much less than the US

[grizzled girder]

lol yea, theres some smart kids

[late trench]

i like the sheet metal frame

[grizzled girder]

cnc cut aluminum 😁

all in all ~125lbs

[late trench]

i love cnc's but they can be hell to own

[grizzled girder]

yea they're

fancy machines

[late trench]

but they need damn good accuracy

[grizzled girder]

I don't own one (way too expensive and nowhere to fit it) but plenty at uni

[late trench]

yeah i like them

my friends often do parts for me if i really need but i keep it minimum

i was actually going to use cnc parts for this 3d printer rebuild but it's a pain sometimes

[grizzled girder]

the sound of breaking a bit is ingrained in my head cuz before we figured out how to actually use the thing properly we broke like 4 bits

[grizzled girder]

well you can always order cnc'd parts

theres sendcutsend

[late trench]

true pain

[grizzled girder]

and fabworks

oh wait are u in the uk

if so I have no clue

[late trench]

no no i just get my friends to do it, its just a pain to use in the final product sometimes

because tight tolerances and shit

[grizzled girder]

oh

just make fatter tolerances

👍

when designing

[late trench]

🐟

it's hard to explain but it's when everything is fitted together, it can introduce issues like binding and stuff because it's so stiff

you have to REALLY pay attention to getting correct squareness and good quality rails

[grizzled girder]

thats what files are for 😁

and drills

and dremels

👍

[late trench]

with mostly no benefit 🐟

so whats the point

har har

hur hur

(im losing it)

[late trench]

cat vomit ftw

[late trench]

reprinting printer parts out of glass filled asa or abs

[empty otter]

got a free spool today

[late trench]

wawa

[late trench]

im a fan

[empty otter]

find the issue

[late trench]

OVER EXTRUSION

[empty otter]

where would that be

[late trench]

ALL OF IT

[empty otter]

goodie

you win

its super fuckin dense

[late trench]

so what was the issue you were pointing out tho

dense does not mean it should be over extruded wawa

[empty otter]

the fact someone set it to 100 infill

[late trench]

fix yo flow rate

[empty otter]

its better on other filaments

this is cf

[late trench]

because u gotta tune flow rate per filament

[empty otter]

i mean i have orca to help with that

i just use a mobile app slicer most of the time

[late trench]

this is tuned flow

that is ASA or abs I think i forgor

tune yo flow boi

[empty otter]

ill try lol

[late trench]

https://ellis3dp.com/Print-Tuning-Guide/ use this i contributed to it

i came up with the flow testing method with him

now everyone uses it apparently

[late trench]

yes

[late trench]

back on the grind

actually resuming building now

[late trench]

ermmmn tuna

[late trench]

rewiring this mf

making new cables for it

[ember gulch]

how much printing have you done compared to maintenance/building 😭

[late trench]

nada

might get a bambu A1 mini

because i have 0 printers rn

my interest in 3d printing is actually tinkering with them not just printing itself

[ember gulch]

dude 😭

[ember gulch]

thats a good starting point

not too expensive yet very reliable

i only got the x1c due to the flow calibration and the set and forget part

[grizzled girder]

NOOOOOOO STOP

thats awful

ah tbf we have one of those at the shop too

at least its all bolts tho

no bearings and couplers or whatever those r

oh I see a pulley too

and springs?? and nuts??

[late trench]

they were sorted but i opened the sorted box upside down

so i can't be fucking bothered

i find things very quickly by looks but yea

weird ability i now have is to know the dimensions by looking at it

[grizzled girder]

Not to shoot u down but a lot of people have this ability methinks

Especially if its common sizes/lengths you work with often

[late trench]

no like weirdly accurate but yea

[grizzled girder]

oh ok

[late trench]

i made new cables forgoring about the spacing issue

[late trench]

mmm yes have to route belts through this shit

THIS PRINTER PROJECT IS HELL

BUT IT LOOKS SO GOOD

[late trench]

Woo

[languid dagger]

just testing out my new smooth PEI plate on my bambu lab P1S

[late trench]

woo I used to use that

but i kept destroying it

don't get fingerprints on PEI or you'll need to wash it with dish soap

[languid dagger]

oh shit

i didn’t know that lol

[late trench]

stuff just won't stick

you can use ipa but it just spreads the grease

[grizzled girder]

I be washing with soap after most prints anyway lol

[ember gulch]

https://share.google/22mek6fVYQxM6WR7o by god this might be the coolest thing ever

ive been looking for a way to eject prints without having the door open all the time and this might be it
very useful for our class that prints a fuck ton of stuff in the midyear and we can't do it all in one day (we could with this)

[grizzled girder]

so its an... automatic door opener?

lol

[ember gulch]

correct

[grizzled girder]

I dunno if I would call that the "coolest thing ever"

[ember gulch]

traditionally you need to have the door open all the time to farm prints with the x1c which can lead to warping since the heat isn't in the chamber anymore

[ember gulch]

it is in my eyes since i haven't seen a better solution

like some people remove the door altogether

[grizzled girder]

well I think its a pretty practical solution

but I don't think its novel

[ember gulch]

well it's my thoughts anyways

everyone has their own situation where something might be useful but not in someone elses

eg i manage the printing happening in the class, and considering how full the queue gets this could be useful

[late trench]

i resumed work

friend has a business account so he can order misumi parts

orange parts will be replaced with blue asa with glass fibre

or carbon fibre

idk yet

either one

we made the toolhead out of annealed pet-cf parts and they're strong af

they get put in boxes of salt and get set to high temps and they get remelted to be stronger

then we may get titanium 3d printed belt clips since they're under high load

this printer is gonna be fast af

[late trench]

should I make 2

[ember gulch]

99% building 1% printing

[late trench]

yes i have moved house and haven't had time to do it

[ionic wigeon]

just finished this for a friend

[late trench]

Nice
I think it's a little overextruded but still nice, can help you with that if you need

[late trench]

YEAH GUYS ITS ACTUALLY HAPPENING

but they're making me run very high belt tensions which are causing all sorts of issues

so i need to replace some bearings which might explode

Tomorrow I'll do wiring because uh my bed parts are missing and probably still at my parents house

[grizzled girder]

yea um looks like a printer to me

👍

u should get a job... professional 3d printer builder

[late trench]

bro the belt tensions it wants are absolute nuts

all that and other things like stainless steel backers to reduce resonances so i can go very fast

aaa

this is by far the fastest printer i've made so far

[grizzled girder]

how to tension

do u just get progessively bigger bearings

I know I've done it that way lol

not on a printer

[late trench]

tensioners

[grizzled girder]

oh ok but thats like

nerdy

thats like if u designed a method to tension ur belts..

[late trench]

tensioners move a bearing along the belt path to cause more tension

[grizzled girder]

nobody reasonable would ever do that.....

[late trench]

anyway they want 190hz pluck tone across 150mm which is nuts

[grizzled girder]

just use gears btw

[late trench]

yes gear teeth marks in my print

[grizzled girder]

just

add more teeth

[late trench]

Shush you

Goober

Yapper

[grizzled girder]

bro someone

pocketted a gear

on the cnc

and I TOLD THEM

[late trench]

👁️

[grizzled girder]

I TOLD THEM

it would snap

they swore

never in a million years

less than 2hrs of runtime later it snapped

[late trench]

yeah uh so u know that medieval tortue device that stretches someone thats literally my printer carriage and the insane belt tensions
they told me i need titanium parts eventually

[grizzled girder]

just use that

self shrinking metal

they did this but instead of

having the spokes

they jsut pocketed all the way down to the flat part

so it was just thin

lol

[ember gulch]

finally 😭

im curious to see what it makes

[late trench]

we getting there

i need to cut a usb cable and put a connector on for the bed surface scanner

[ember gulch]

how many printers have you built bro 😭

[late trench]

yes

[ember gulch]

Good response!

[late trench]

just throwing it together ATP i need to test the gantry

yes i broke a wire ill fix it later

[grizzled girder]

@foggy rose

[late trench]

noo

im not even half done

[grizzled girder]

u said ATP

[foggy rose]

If only you knew how uncomfy things really were

[grizzled girder]

I'm doing you a favor

looks like atps setup tho

[foggy rose]

False

Mines better

yours doesn’t even have a blinking GPS antenna when it’s in sleep mode

[late trench]

yes it does i sent 24v 30 amps through a thermistor port so it does blink

[foggy rose]

okay but it’s not GPS

and STOP DOING THAT TO YOUR CHIPS

computers were never meant to see the horrors above 12 volts

[late trench]

analog pin suddenly reading 24v

https://tenor.com/view/shocked-surprised-gasp-what-cat-shock-gif-635629308990545194

[late trench]

replace fuse with metal pin type shit

[late trench]

WE HAVE POWER

[late trench]

NOT DODGY AT ALL

[charred jay]

this would not pass certification

[late trench]

NOT DONE

[charred jay]

can this printer murder someone when its done

[late trench]

maybe

raaaagh im just throwing wires in atp because i need to do a full rewire anyway so as long as it gets printing soon idgaf

just wiring from memory

[late trench]

raspbian nuked itself

[ember gulch]

least wacky raspbian install

[late trench]

ok i finished making the cables

It's printing

[grizzled girder]

I dunno man it looks pretty slow to me

[late trench]

YEA NO SHIT

it hasnt even got input shaper enabled

[grizzled girder]

got u

[late trench]

I'll crank it up later when I tune it

[late trench]

Still slow but still tuning it

[grizzled girder]

I dunno man it looks pretty slow to me

[late trench]

i have noooooot tuuuuned it

[late trench]

More tuning, only 500mms on travels tho so we'll see

Thing slowing down the print is layer times to prevent overheating but eeeh

This is an old roll of PLA since I don't really print pla

I tend to only print ABS or ASA

Had issues with the printer going into shutdown because the fan was too fast and thought it stalled

Just changed tacho settings

15k rpm 🤣

[ember gulch]

explosion reported in apartment complex

[late trench]

[late trench]

@grizzled girder THIS IS NOT EVEN FULL SPEED

[ember gulch]

are you using mf bambu studio??

or is that prusa

[late trench]

no that's orca slicer

[ember gulch]

oh

ui looks similar

[late trench]

I'm pushing 500mm/s 50k accel

but i might go 350mms at 70k

top bambu maxes out at 20k I think lol

earthquake generator

[ember gulch]

oops time to put a concerte slab

[late trench]

yeah it's vibrating the floor a lot

Reducing it to 20k otherwise it'll shake itself apart, but can set it to travel at 600-700mm/s

If it reaches 50k it should reach maybe 1000mm/s on 30k

[ember gulch]

did it finish a print at whatever it was set to before that

if so can i see

[late trench]

I'm currently tuning it so I'm playing around with settings and cancelling prints a lot but i think this was it

this is a 9x9 bed mesh using the beacon surface scanner

[ember gulch]

this is suprisingly good wtf

[late trench]

i need to fix print quality a bit, the wood grain is from broken extruder

[late trench]

the outside is 8k max, input shaping limits
infill goes up high speeds

so not too impressive lao

you dont really want to run perimeters too high otherwise it ruins overhangs and stuff

[late trench]

lights and bed fans

[late trench]

im printing a sheet to test if my printer is pulling/pushing the toolhead during scanning but seems ok

[late trench]

i couldn't get a flat printed sheet, even with the best beacon surface scanner, turns out the plate is fucked

thicker one side and skewing results

the surface scanner can only see metals and not powder coating

[late trench]

THE BELTS FINALLY BROKE

i cant believe the clips didn't break first, they're made from annealed PETCF so yea kinda strong

[ember gulch]

you just built that thing...

[late trench]

YEA

they lasted 7 hours of print time

[ember gulch]

are those brand new or 😭

[late trench]

naur

old belts

[late trench]

to do this to gates powergrip belts is pretty hard

[late trench]

ok it's working again

has to go slower due to it literally shaking the floor and having people live below me

me when 100% part cooling on asa

[late trench]

I pushed the motors so hard I need cooling for the stepper drivers im not even kidding

Otherwise they'll thermal throttle by knocking the current down and it'll fuck prints up if a step gets skipped

[late trench]

@viscid sierra NOT JOKING

WIRES ARE A MESS RN

[viscid sierra]

WHAAAT

😭

so much things

[late trench]

YEA

[viscid sierra]

ooh i see a pi :D

[late trench]

THE OTHER PRINTER IM STILL DESIGNING

[late trench]

YES

[viscid sierra]

OTHER??

how many do you have :o

[late trench]

just this one and my other one in parts but i needed to redesign it

this is muh other one

[viscid sierra]

wohhh

looks so cool :D

[charred jay]

but can it run doom?

[late trench]

yes

it can run minecraft

they have raspberry pi's

black/grey one has a pi zero 2w and the grey/blue one has a pi 4b

[charred jay]

how many cables go out of this printer

im assuming power and ethernet

[late trench]

Just power usually
Bigger printer has usb and ethernet at back but they don't get used really

The printers are controlled over wifi but yeah if they're someplace else then I can just hook up an ethernet cable directly

[charred jay]

oh ok they use wifi

[late trench]

yea

the black one doesn't have a screen or interface, only usable through network

[charred jay]

what does the pi host

[late trench]

runs basic raspberry pi os with kalico*, moonraker web api and mainsail interface

[grizzled girder]

looks slow

wires look good tho

I dunno wym by a mess

[late trench]

No they're fucking atrocious

[grizzled girder]

um

[late trench]

by my standards

I prefer wires cut to exact size needed

[grizzled girder]

clean or messy?

[late trench]

and have it tied down in routes

[late trench]

Both

[charred jay]

you should give the printer a big ass e-stop button

[grizzled girder]

does this make u feel anything

[late trench]

I was gonna add some buttons but yea

[grizzled girder]

the wire bundle next to the chain

[charred jay]

it would be very funny lol

[late trench]

zip ties do their job

i had to add cooling

because i ran the motors with such high currents and tension that they started to overheat

[charred jay]

does that board control the motors or what

[grizzled girder]

hey they are labelled tho

thats pretty good

[late trench]

yes that board controls most of the motors and stuff

[charred jay]

wait are those screw terminals power inputs or outputs, im assuming inputs

[late trench]

the toolhead has its own separate controller board as to reduce wires, then i only need 24v, gnd, canbus in and out

[late trench]

the ones under the red cover are inputs

the black ones are outputs

mosfets that send 24v where needed

[charred jay]

why do you need both motor power and power terminals

[late trench]

because they aren't tied together

motor power isnt linked to general power in

[charred jay]

are they different voltages?

or is the motor power just a deicated thing with the same voltage

[late trench]

Nope, just how the board is

The motor power is just joined onto the main power cables

[charred jay]

oh ok

one last thing

what would the bed-power be for

can it control that?

[grizzled girder]

we actually did pretty good (in terms of electrical work) on that robot

[late trench]

so the bed power port is intended for beds being run off the control board mosfet
as you can see, it has bed in and out

[late trench]

but this is only for dc voltages

[charred jay]

you are running yours off ac right

[late trench]

my bed is a thick aluminium plate and to run dc, i'm going to have a huge power supply needed.
so i went directly with AC power

[late trench]

its nice

[grizzled girder]

I was gonna say pretty sure no major failures but nah there was 1 at a competition lol

[late trench]

u in like mit or some shit

my classmates dont know a thing about coding

and we're in computer science

[grizzled girder]

no bruh I ain't smart enough fort hat

MIT rejected me

😁

in fact MIT rejected everyone who applied at my school

they haven't accepted a single person from my HS in a decade

must've really hated the last guy they let in

[late trench]

So what I've done is hook some small cables up to an output that controls a "solid state relay"
it allows ac power to flow through if triggered
so yes my control board handles the bed heating but not delivering the power itself

[late trench]

guh

[grizzled girder]

ye its really just having passion for it

[late trench]

Fuck off

u totally could

[grizzled girder]

atp is rlly good

and smarter than me

but atp is in HS bruh

not even

I dunno wth atp is in

[late trench]

i dont know how atp gets motivation to constantly learn new things

[grizzled girder]

yea with that SLEEP SCHEDULE

I would be dead

[late trench]

🐟

[charred jay]

https://cdn.eilioimacat.xyz/u/7rWy0c.png

is this thing a whole computer or no

it looks like it has a ethernet port

what can it do with that

[grizzled girder]

we had hella brownouts and after electrical blamed software for 30m they finally realized that half the strands in this main breaker wire weren't int he crimp or whatever loooool

[grizzled girder]

nah chill I can't be complacent or im gonna end up stalling

[grizzled girder]

also #BlamingSoftware

its always code thats the problem

😁

[late trench]

not much, general local applications
it's not very powerful
it depends on what software you flash onto it

it's a control board, specifically the BTT Octopus v1.1
it has the I/O neccessary for handling fans, high power loads, motor drivers, servos, etc, something a usual raspberry pi can't do

traditionally entire 3d printer softwares run on these but the software i use relies on the pi as a host and the control board gets controlled by it through USB signals

[late trench]

i lost a lot of IQ due to strong medications i think, still haven't recovered

[charred jay]

Ok

[late trench]

can't code for shit atm

[grizzled girder]

oh wth

medications for what?

[late trench]

Lol this sounds aggressive

[late trench]

Paranoia anxiety depression the lot

[grizzled girder]

trust its just practice

it'll come back to u

[grizzled girder]

o ok

is it better now

[late trench]

I had to cancel my last year of university due to it bu they're letting me finish it off, averaging like 72%

it's meh, on my old ones now, but i feel really slow and dull

hard to come up with code ideas

[grizzled girder]

damn sorry to hear that

[late trench]

it's like the feeling where u forget a word and you feel stupid/lost trying to remember it
but thats how i feel most of the time now lol

hopefully it will wear off

[late trench]

thank, hopefully will pass

[grizzled girder]

a friend of mine that I know really well and was extremely smart developed neurological problems (he had a seizure out of the blue one day, then continued to have them), he got on meds that helped manage them but I really think they hampered him or made him less able to pursue what he wanted and reason as well as he could before

[late trench]

@charred jay bed setup

[grizzled girder]

not sure how similar this is to ur case

but you saying that reminded me of it

[late trench]

yeah medications suck, i feel like they only work by making you more slow, less quick/irrational thinking

and it's stuck atm

[grizzled girder]

hes doing better now but it was really noticable once he was on the meds

rlly tragic cuz it hit right as he was getting ready to apply for college

[late trench]

yeah, people said i was a different person on my worst meds, i could hardly talk and constantly lost balance
i don't remember a THING from that month

[grizzled girder]

ouch

[late trench]

damn it sucks a lot

[grizzled girder]

yeah rlly does

but hes been getting stuff back together

[late trench]

glad to hear, hopefully he recovers

thanks for being open and understanding with me

[grizzled girder]

and you sound like you're on that track too so thats good

[late trench]

bro i hope

[grizzled girder]

ye no worries

[late trench]

i got referred to an ADHD specialist too so thats fun

[grizzled girder]

well I hear insurance is a little better there right..

I dunno. I hope so at least

[late trench]

i dont pay anything

[grizzled girder]

its a mess here!

oh

lol

[late trench]

in uk we have free healthcare but it's degrading a lot

[grizzled girder]

degrading?

oh like the quality (of healthcare/healthcare services)?

[late trench]

yeah like getting slow, long waiting lists

[grizzled girder]

o yea

im super used to that

its the same or even worse in china

can u imagine

[late trench]

they told me it'd be years until i be seen by their adhd specialist but they referred me to a private specialist and are covering the costs

[grizzled girder]

1.4 billion people

[late trench]

god damn

[grizzled girder]

I mean its to the point

[late trench]

china is growing quick, not just people but infrastructure, they actually get stuff done instead of fucking about for months trying to find reasons not to do something

[grizzled girder]

heres something that surprises a lot of people

depending on the first 2 letters of your randomly assigned license plate

that determines the 2 days of the week you cannot drive that car

why? cuz theres too many cars

[late trench]

guh????

[grizzled girder]

is it a good idea? kinda. the rich just buy many cars with many plates, then they just pick the car they can use on that day

[late trench]

ah yes of course, rules not applying to them

[grizzled girder]

cars from different provinces (like US states) can't get on city highways on certain days at certain times

[grizzled girder]

oh they apply, but they can just buy like 4 cars..

have enough license plate variations to cover all the days

lol

[late trench]

yea i get that but

its like

[grizzled girder]

yea its very very different from the US and I imagine the UK too

[late trench]

general rules don't apply for them because they can just pay their way out of it

[grizzled girder]

I would 100% suggest visiting

[late trench]

here they try to delay things as long as possible

[grizzled girder]

just to experience what its like

theres definitely good

and theres also bad

[late trench]

yes i actually want to

[grizzled girder]

but it is just so different

[late trench]

people are like china bad but im like
it's not THAT bad

[grizzled girder]

its not rlly bad at all

most people are nice

[late trench]

language is hell to learn

[grizzled girder]

esp. people in big cities

they see foreigners a lot

I hear japan can be kinda anti-foreigner tho..

maybe just a rumor/gossip/whatever

all homogenous societies will be to a certain extent I guess

[grizzled girder]

oh yea fun language too!

[late trench]

NO

[grizzled girder]

also another funny thing

people who were born in the US

or live in the US

or I guess in any country where you can

vote and stuff

they're like

"how do you live in china you can't vote"

bro.. I just.. don't care?

lol

they ask how the chinese people can sit there and be ok with not voting

and im just like.. theres no expectation to be able to (no precedent)

so... nobody really cares?

we just go about our days not rlly thinking about that

ok I totally derailed this but good talk

hope u set yourself on a good path and keep to it

thanks for the kind words

[late trench]

no u

sorry trying to do multiple things but i am reading, just late responses

[grizzled girder]

Nah no worries I gotta run anyway

[late trench]

cya, nice talking with ya

[languid dagger]

i’ve had enough of this

[ashen lake]

[ember gulch]

god the x1c is the best purchase ive made in a while

i love i can just tell it to print this even while im not at home and i come back to something absoultely perfect

i just put a new buildplate on it that isnt even the same material and it has zero issue whatsoever

[languid dagger]

is there anyway to stop warping

my printer does not have a heated build plate

[mighty pulsar]

average cad experience (the hole relocated itself??)

[ember gulch]

cad softwares are kinda just the equivalent of microsoft word but for modeling

https://youtube.com/shorts/T2lgRadzk-0

[mighty pulsar]

fr

[mighty pulsar]

finished this bridge for a engineering project

[charred jay]

im trying to learn onshape for class and sometimes i can not figure out what I am doing wrong

😭

[mighty pulsar]

oh im good at onshape

[ember gulch]

this is apparently the best possible orientation according to bambu

not something flat, it apparently should stand

what the fuck 😭

[grizzled girder]

and it really is!

I would not print that flat lol

[ember gulch]

yeahhh but like

it has a much higher chance of falling over when its printed upright

its better to use supports while its facing the bottom

(i care about detail here)

[grizzled girder]

not rlly

you'll need to print with supports

assuming good tree placement theres practically 0 chance it falls over

[grizzled girder]

not rlly

you're not gonna get the detail you want out of that print if you print it flat

just print it upright with supports

[ember gulch]

i am lol

[ember gulch]

theres no detail on the bottom

theres detail on the top

aslo the infill is absurdly low

since we're running low on the filament we need for this project

(5% gyroid)

its a prop so it dosent need like high infill

[grizzled girder]

idt u understand what im trying to say

printing it flat means you don't get the same resoluton since your layer lines will be against the detail

instead of along it, which upright would be

[ember gulch]

good to know then

we already started the print so

[ember gulch]

yeah i wonder why

i stg i aint printing shit for anyone at my school if they dont send me optimized models

[ember gulch]

god i can really not express how much i love my x1 carbon

i love i can just leave it untouched for like a week or two

then if i need something quickly like a pcie bracket i dont need to fuck around with calibration

it literally just works

i just wish this was open source

most errors that come from this thing are from user error and rarely from the actual printer

not like this thing is immune to errors but most of them are easy mistakes on my end

[mighty pulsar]

laser cutter

[mighty pulsar]

@charred jay big scary laser cutter

[ember gulch]

love my x1c so much

dont need to bullshit around with it or recalibrate it or nozzle flow or anything

people do not joke when they say these fuckers are set and forget

i just wish it was open source

[ionic wigeon]

Popcorn bucket

[ember gulch]

school got the h2d
i set this thing up all by myself and it quite literally worked out of the box

it needed like half an hour for initial calibrations but it hasn't errored once

hell i didn't even need the manual

[sudden linden]

@late trench I printed a spaghetti
