Yet another 5020 toolhead (Clogged hole/AMOGUSBURNER)

[clever charm]

form modeling is really different

[warm bane]

Atom knows how to do it

But he's on a break

He's a wizard

[clever charm]

good to know, i'll annoy him with it. but i'm starting to get a hang of it and want to learn

[warm bane]

You can always ask chatgpt

[clever charm]

that looks really cool

i think it's time to sim

[high sun]

brother that looks mad good

[clever charm]

simulating this will be a real challenge huh

just preparing it to be simulatable is head spinning

[drifting tusk]

airshaper <3

[clever charm]

ah yes

[drifting tusk]

don't they have a free tier?

[clever charm]

currenlty looking with simscale, and if i can't get what i want with the free stuff i'll try openfoam

[clever charm]

i think they have a free demo

also i think that it's a bit overkill for what i need it to do

hm so with burner emails i can get basically unlimited simscale sims

[drifting tusk]

https://tenor.com/view/waow-based-wow-thinking-doodle-gif-12262272166408784207

[clever charm]

that was painful

[celest vector]

amogus

[novel spruce]

the design give stag beetle vibes XD

i didnt see is this the design for the default fan or you gave up trying to salvage yours and its for another fan?

[clever charm]

Oh yeah it's dead dead

And I'm not paying for a oversized fan

[novel spruce]

https://giphy.com/gifs/fan-death-3oFzmrqh43AvYwn9Cw

so for what kind of fan is this designed?

[clever charm]

Wide mouth 5015 like most other printers

So really really cheap and also lighter fans

[clever charm]

🤞

i should try to get some to run locally...

[clever charm]

i should be concerned... you're not the first person saying that

5020 one was truck cab now this is amogus

[clever charm]

bruh

so i clearly need to improve the splitting cause there is still wayy too much on the left side (image is from the back) and also aim down a bit further

[clever charm]

also i should reduce the intake size for the next sim

[tropic gazelle]

👍 and dont forget a carto mount 😆

[clever charm]

i can guarantee you that i might look into doing that if you provide me the links for the carto and how it should be ideally mounted xD

[tropic gazelle]

https://docs.cartographer3d.com/cartographer-probe/installation-and-setup/probe-installation#mount-cartographer

[clever charm]

still not there

it's already better but gotta work on asymetry

also idk why but the particle trace doesn't go all the way

yeaap not ideal

ahem shit. that's from the a4t github

btw i kinda treat this as a todo list as i have goldfish memory capacity

move ducts forwards a bit more, inlcude test with part

@noble mesa what's your opinion on a backflow inhibitor?

also smaller duct outlets maybe. but i'd need the actual fan to know what outlet size is optimal

[clever charm]

3rd duct, let's see if the sim is generous now

[warm bane]

just copy voron bro

with their stealthburner

[clever charm]

@green berry please ban that shit

[warm bane]

cant perfect perfection friend

[clever charm]

it's a perfect pain in the ass yeah

[warm bane]

as a proud 2.4 owner me so proud

[clever charm]

i'd rather use a bowden extruder with revo nozzle and no part cooling

[warm bane]

bowden haters have no valid reasons.

https://giphy.com/gifs/yeah-speed-ishowspeed-D63HGAzG15LQrjBPRE

[clever charm]

now testing with part to cool

[tropic gazelle]

stealth is heavy and the airstream is shit!

[warm bane]

no

https://github.com/kevinakasam/WTH-Burner

[clever charm]

what the fuck is wrong with people

[tropic gazelle]

Back then, I converted my Ender 3 to use a StealthBurner.... I'm familiar with it and its quirks.

[warm bane]

i love vorontards

[clever charm]

you mean shortcomings....

[tropic gazelle]

It really looks great... design-wise 😉

Darth Vader on a printer .....

[warm bane]

it has funny angles

thats it

and leds

[clever charm]

it looks like someone was too stupid to model smooth shapes and resorted to low poly, i know it's on purpose and probably more work than smooth shapes. but whyyyy

i don't like the only good thing it has going for it

[tropic gazelle]

voron style 😉

[warm bane]

he had only stls

and those were low res

[clever charm]

who?

i was talking about sb in general

[warm bane]

SB?

What

[tropic gazelle]

You’ll always find these angles and this design in Voron’s products. Whether it’s printers, accessories or anything else...

[clever charm]

stealthburner

[clever charm]

ah yeah the typical pro gamer look

🤮

[warm bane]

I wrote poor voron engineers at the end but my Internet died thanks germany

[clever charm]

bambusleitung am start

[warm bane]

Ich liebe mein Netzanbieter

[tropic gazelle]

*looooooooooool" also bitte leute!

[warm bane]

Ich meditiere ja schon

Huusa

[tropic gazelle]

ich habe die magenta lte flat .. und bin zufrieden g

[warm bane]

Du lebst aber auch nicht im vergammelten Ruhrgebiet

[tropic gazelle]

nö .. im saarland

[clever charm]

ruhrgebiet ist da wo instandhaltung gekonnt in ruhe gelassen wird

[tropic gazelle]

bochum ist doch auch dort? fg

[warm bane]

Daher kommt auch das Ruhr im Namen munkelt man

[warm bane]

Bochum ist eine Junkie Hochburg

War da studieren

Direkt abgebrochen

[clever charm]

zuviel gekokst oder was? 🤣

[tropic gazelle]

Herbert 😉 ... TIEEEEEEEEEEEEEEEEEF im WEEEEEEEEEEEESten

[clever charm]

eitherway back on topic, sim 3 is now runing

[tropic gazelle]

back 2 english g

[warm bane]

https://youtu.be/OvauzdH0fHY

Eines noch

Ok sorry

[clever charm]

got an idea what to put on the front face?

[tropic gazelle]

no elegoo logo ... COSMOS! whate else?

[warm bane]

American fridges circa 1960s

[clever charm]

oh good idea

[warm bane]

I think it looks cute

[drifting tusk]

dickbutt

[tropic gazelle]

u can print it in blue, yellow, black or any other color gggggggggggg

[warm bane]

But if we make it we have to use red fillament

[clever charm]

but you have to print and use i then

just ignore your cpap

[warm bane]

Cpaps you dick

[clever charm]

https://giphy.com/gifs/DogeBONK-bonk-dobo-dogebonk-qs4ll1FSxKnNHeSmom

[drifting tusk]

if you add support for the stupid magnet thingy that's in the new toolhead cover for the CANVAS, sure

[clever charm]

it's already got a blower fan

[warm bane]

I'm cpaping it rn

[clever charm]

i think double siding the magnet to the back of the fan should work, there isn't much room

[clever charm]

does it basically sit flush with the back of the fan?

[drifting tusk]

yeah

[clever charm]

hmmmm i'm not sure that it fits

[drifting tusk]

mm

then the new extruder also won't fit

(cuz it has a PCB on the front to detect runout)

[clever charm]

how much does it stick out?

[warm bane]

Does that mean that all existing toolhead covers won't fit ?

[drifting tusk]

not at home atm

@fallow orchid can you measure the runout sensor PCB?

[clever charm]

you probably need to get a cc2 one

[warm bane]

[drifting tusk]

the canvas upgrade kit comes with it

look at the manual I pinned in #research-ams

[tropic gazelle]

and don’t forget the Constellation Extruder

[clever charm]

oh yeah that's 10000% compatible

[green berry]

https://tenor.com/view/bebezinho-gif-17524909461832763406

[tropic gazelle]

pffffffffff... Did you forget your beer? 😄

[clever charm]

waits faster

[tropic gazelle]

5020 Blower, 4 Pin ...

[clever charm]

aye that's cheaper than what i've seen

but also not compatible

[tropic gazelle]

i know ... fuck elegoo

[clever charm]

eh idk, the cooling performance of the cc talks for itself. it's quite impressive

[tropic gazelle]

elegoo is asking for €16 plus delivery costs for it. All in all, it comes to nearly €25 and you’ll have to wait two weeks.

[clever charm]

hear me out

what about

[tropic gazelle]

My fan keeps cutting out... but I think I've found the fault now. It's just that odd connector on the toolhead

[tropic gazelle]

The fan does the job well. It’s not quiet, but it’s effective. But the fan is an Elgoo model (not a standard fan) and the connection between the tool head and the circuit board… that little plug/socket… sorry.

[green berry]

ran out of alcohol

[clever charm]

perfection

[tropic gazelle]

com'on ... not a horse g

[clever charm]

nope that's indeed not a horse

it's a HONSE

[warm bane]

Pls add hexagons

[clever charm]

https://giphy.com/gifs/no-bugs-bunny-fXnRObM8Q0RkOmR5nf

[warm bane]

Will you release step files

[clever charm]

i'll make the step available, then you can do whatever you want

[warm bane]

?

[warm bane]

Honse out of hexagons

[clever charm]

tbw if you want me to include some face modifiers just send them my way and i'll add them to the model, or do a remix if you want

[tropic gazelle]

just COSMOS !

[warm bane]

I'm joking bro

[tropic gazelle]

the only face modifier

no Honse, no Ottifant ....

[clever charm]

@vernal harbor would you be willing to make a icon type version of the cosmos logo you did? in svg? 🥺 👉 👈

[vernal harbor]

I can try and learn illustrator

this as svg right?

[clever charm]

this woudl be cool in general, but also idk a reduced version that would not have fine details so it can be printed easily

[vernal harbor]

Ill have a mess around and see what I can do for you

[tropic gazelle]

If you like... you can also send me the file and I'll convert it to SVG.

[clever charm]

my main concern is to have the line be at least 0.4mm wide on the toolhead, which would either mean cutting most of the logo out, or scaling the line up to be thick enough

the workable area is about 50x30mm

[tropic gazelle]

this line 😉

[tropic gazelle]

quick and dirty drawing .... without beer g

[clever charm]

that's a bold assumption

about that, gonna fix this

brb

[tropic gazelle]

@green berry PARTYTIME! @clever charm goes to get a beer 🍻🍻🍻🍻🍻🍻🍻

[fallow orchid]

Currently in bed sorry

Here's your approximation ig

[drifting tusk]

🫃

[clever charm]

inching closer

[clever charm]

thank you, that is never ever ever gonna fit

welp need to push the ducts back a bit but that's getting pretty even now

[green berry]

put them on diagonal

[clever charm]

from what i've researched, directly opposing ducts are really good too

[green berry]

you want to cool part not nozzle

bigbrain~2

if u combine the airstreams directly you get turbulence on nozzle

you want air to blow over part and away

[clever charm]

ah k, like get a vortex that spares the nozzle

[green berry]

just angle them a bit

doesn't have to be more than 15 deg

offset

[clever charm]

doing that in the internal duct should be fine right?

[green berry]

blowers have enough pressure to overcome ducts

just do not do 45 deg bends

like keep them as smooth as possible

[clever charm]

that's the ducts as simulated

[green berry]

you are simulating smooth ducts

your printed ones won't be smooth

show inside here

[clever charm]

maybe close enough to at least tell me if i'm pushing the air out the wrong nozzle xD

[green berry]

you are designing an air duct not a car

you are okey

[clever charm]

that's one sharp thingy

[green berry]

yeah make it a bit round

[clever charm]

2mm fillet?

[green berry]

whatever

just smth a bit round

no pointi edge

pointy edge is worse

[clever charm]

for the angeling of the airflow, i can keep the duct outlets the same and just change the shape before right?

would make this a lot easier

[clever charm]

just wanna learn

[green berry]

change this 15 deg offset

and call it a day

make the curve smoother too

[green berry]

sir this is wendy

we print then research

[clever charm]

i can't print and research cause my cc got no fans

[green berry]

you have aux fan

[clever charm]

what should i test a duct for that i cant even blow air through

[green berry]

put your mouth over it and blow

you have 2 lungs

👀

[clever charm]

now tell me how i should imiate a 5015 blower fan with my lips and then come again xD

doubt i can get a somewhat tight seal in there

[green berry]

you are testing flow not power

👀

otherwise get some 20k sunons

and call it a day

[green berry]

do you think your fan is sealed?

[clever charm]

the point is not to have a quick fix, but to actually make a good part cooling setup, without resorting to mad power

[green berry]

lmao

[clever charm]

just tried it btw, i can't feel anything coming out of the ducts

[green berry]

if I show you what takes to design a perfect air duct

you are gonna call me insane

so in the meantime don't

[clever charm]

probably won't, and i know that i'm very far from perfect

[green berry]

also printing the duct breaks any smooth air inside

👀

we just pray that fan pressure is enough to overcome those

then you should also check for tightness of the print

especially if 2 walls thin print

[clever charm]

doubt i will be getting near pressures where that's an issue

specially not on the cheapest 5015 fan i could find

[green berry]

if u do a 90 deg bend I wish you are gonna see

that's why u should limit to 45 maybe 60

bends

[clever charm]

well i try to limit the bend as much as i can, but don't think that i can make it any straighter than it currently is without some major sacrifices

[green berry]

again just try your best

and print a lot of tests

you can test flow with a glass of water under nozzle

you want air to hit under nozzle not on nozzle

[clever charm]

woudl you be willing to do that?

[green berry]

no, cause you don't have the apps

the math is over my paygrade, I just know how to use the apps and common logic

your worst enemy is 3d printed duct

not the path itself

you can check that with a texture over the duct

and resimulate

[clever charm]

will try that if simcale allows it.

[green berry]

on low airflow it doesn't matter

but on 12-20k rpm fans

you will hear the difference

we used to vapor smooth abs for those

I think you have wall roughness

setting

also what model are u using?

if I am not wrong 0.5mm roughness should be a good setting to test

[clever charm]

incompressible - k-omega SST if that's what you mean

[green berry]

any toher k omega?

any other?

[clever charm]

those are the models availble i think

[green berry]

okey sst

what are mesh settings?

[clever charm]

the defaults

[green berry]

go 3 on fineness

or 7

which is finer?

👀

sorry I don't use simscale

[vernal harbor]

im not sure if those are great

[clever charm]

ok so just finest

[green berry]

not finest

but more fine

what settings do you get for automatic boundary

or that isn't a drop down?

[clever charm]

they absolutely are, thank you !

[clever charm]

mind to join me in vc?

[green berry]

yes

cause going to sleep

it is 3am

and I have work

kek

just expand the menu

[clever charm]

lol

:kek

[green berry]

do 5 layers

rate 1.2

relative thickness 0.6

now go find wall

settings

[clever charm]

bruh that's gonna be super annoying to select the right faces... fml

maybe i'm missing something, but wall should be in bc's right?

[green berry]

well u can try without wall setting

[green berry]

also yes

boundary conditions

[clever charm]

just tried selecting stuff and it's quite easy

[green berry]

there should be smth calle wall roughness setting

[clever charm]

those are the settings

[green berry]

wall function

no slip

no roughness?

[clever charm]

seems like it

[green berry]

custom option?

[clever charm]

maybe in there?

[green berry]

nope

should be in bc

custom walls

or smth

[clever charm]

yep it is

[green berry]

no slip

[green berry]

wall function

constant 0.5

height

what units do you have

?

[clever charm]

like default units?

[green berry]

0.0005 m if no other option

[clever charm]

S.I

[green berry]

that should be 0.5mm

[clever charm]

ok so that probably should be closer to 1

[green berry]

ahhh

prolly

shouldn't influence that much

that's why I went with 0.5

0.5mm

0.5mm would be worse case

[clever charm]

i think worst case is a really good starting point

[green berry]

now send it

[clever charm]

still fighting with t splines

that look better?

[green berry]

a bit

find a way to seal the fan better

add a rim

or smth

[clever charm]

it has one, for the sim i just have the fan fused to it to make it simpler

[green berry]

ah oky dokye

[clever charm]

also i'm not using that cad for the sim

those blades 💀

[green berry]

kek

[clever charm]

also what fan inlet size should i go for?
should i aim for not having any air escape the fan?

or is a bit acceptable to have less restriction

idk if that's normal, but when doing particle trace i need to place the origin inside the duct or else i don't get the traces to go out

i take it that this means normal?

anna ouija board vibes

ffs

fuck you

also thank you a lot

but still fuck you

[noble mesa]

have you done cfd on acctc?

[clever charm]

nope, not at all. want me to do so?

ig it would also apply for gamma

[noble mesa]

yeah that would be great if you can. You doing this in fusion or what?

[clever charm]

nope, simscale. got 10 sims for free

now prepping my 4th

[clever charm]

would you be willing to prep the cad? it's quite a long procedure and i got it all setup in the timeline for the 5015 fan. idk how i'm gonna call it

[noble mesa]

I can but can't do it for a few days prob. I might actually do it in fusion or comsol or fusion since I have unlimited credits. was it that hard to pick up simscale?

[clever charm]

not at all. watched a tutorial for an impeller pump and i'd say that i had a sim up and running within an hour or so (once the model was prepped). Most stuff that i need to touch is pretty self explanatory, and the stuff that isn't as much atom has explained it here

[noble mesa]

cool once I learn if you need cfd I can prob run on my end once you run out of money

free FEA and all fusion extensions. Almost makes up for the 30% pay cut you take to work in academia

[clever charm]

wanted to look into running it locally too, but idk if i'm ready for the headache

[noble mesa]

sounds painful

[clever charm]

about that, i've been accepted for my studies and am gonna have a whole suite of cad to play with

[noble mesa]

holy fuck how old are you

is this undergrad

💀

[clever charm]

well less old than you 🤣 since i already told you xD

[clever charm]

yep....

22

[noble mesa]

I'm old man I dont remember

[noble mesa]

Oh but youare an adult ok cool

yes you will prob get free software

deff free fusion with all extensions, though autodesks website kinda sucks for that

depends on your institution which other ones you get.

[clever charm]

i think i'll get solidworks and catia, don't quite remember what software we are gonna be using

[noble mesa]

Yale: fuckloads of good software
Backwoods, west virginia christian college: good luck

[noble mesa]

you will get more than that

you have to trawl the instutions website and software portal

but usually there is a ton of shit that is accessible but not like broadcast

[green berry]

hello kiddo 👋🏻

[clever charm]

shouldn't you be asleep?

[green berry]

I need to assemble those myself

cause the author had the briliant idea of not doing a damn ams print cause what's printing and gluing 30 1mm parts

like bro

[clever charm]

is there even clearance?

[green berry]

and I've already print one like the guy intended

but it doesn't fit well

it is either too loose or too tight

yes the white part doesn't fit into the black one

that's where I gave up 2 months ago

on printing this

it barely holds itself upright

[clever charm]

it's sad that i was able to tell from the screenshot

[clever charm]

good luck

[green berry]

so now I am trying to assemble some

like eyes

hat

body

feet

and glue those instead of everything

do we know a good stl assembler?

[clever charm]

have never tried it but apparently meshmixer is good

[green berry]

orca has smth

but works awfully

especially for organic prints

done with fucking ai

or whatever

like

and I have to manually move bit by bit until it fils the hole

and also adjust size

[clever charm]

i should really try that. looks cool

[green berry]

you can fix face to face and point to point

if the shapes are okey

like circle, square face

it is easy

if u get smth like mine nope

[clever charm]

so tl;dr don't print shit

[green berry]

yeah well at this point

remaking entire model from scratch would take same time

and I need to print like 2-3-4 pieces

so not worth my time

so quick hack

[noble mesa]

yes, yes he should

[clever charm]

https://giphy.com/gifs/mkhMTALnrYRLnuoe5P

[green berry]

good night

[clever charm]

fusion on linux is really funny

[lusty bronze]

lol yeah

[lusty bronze]

which desktop environment is that?

[alpine quartz]

https://www.youtube.com/shorts/pq0Anj9pKkc

i dont quite understand why he makes 2.0 when this exists

[drifting tusk]

[warm bane]

Gnome no?

[clever charm]

Yeah it's gnome

A bit bloaty but I really enjoy it

[clever charm]

I mean if he makes better cooling ducts I get the point

Not to bash on bacon but there is a possibility that his toolhead will have the best cooling performance

[clever charm]

atom making simscale sweat

that's hopefully gonna be a nicely detailed sim

[clever charm]

fillet madness

i wish that freecad will be able to do this one day

[clever charm]

that looks quite good with my untrained eyes

maybe narrow down the duct on the right side to curb the turbulence

and got a small vortex just at the nozzle

also that looks like an issue

i think i should put the flow splitter a lot lower and have the duct a lot noarrower from the get go

https://giphy.com/gifs/scorpiondagger-scorpiondagger-ouija-pervy-XaO4yoeSvwBA4

thank you

[clever charm]

@green berry what do you think about this?

would be nice to have a tool that can show you cross section along a path of a surface

also offset the outlets a bit to help the air not go straight down

[green berry]

5/7

[clever charm]

how do i get 2 more?

tried making the curves a bit smoother

[green berry]

you get me a bottle of alcohol

and fix my bmcu

1 slot died

and I am at work

and print has 6 more hours

🤡

[clever charm]

what kind?

i have some pretty nice wine locally

[green berry]

whatever kills me faster

[clever charm]

i got some 97% burning alcohol for cleaning my printbed if you want

and also some not denatured high proof alc

[warm bane]

Would it do something to move the fan closer and make the ducts shorter

I know it's a packaging issue but just curious

[clever charm]

i think bacon atom and i agree that longer and smoother ducts are better than short ones

[warm bane]

Why

[clever charm]

sharp direction changes create a lot of turbulance

best example that comes to mind rn is rear view mirrors, when you drive at speed you can hear how fucking loud and violent that turbulence is

basically you want all your energy going into making the air fast at the print, not making it spin inside the ducts/making noise/heating up

[warm bane]

I mean yea but longer ducts also make you loose airflow

But eh

I'm no engineer

[clever charm]

me neither

[warm bane]

And haven't researched it

[clever charm]

yet*

[warm bane]

But my reasoning is long ducts less airflow so less power

But there are more factors which I haven't perhaps considered

[clever charm]

like here is a good example, there is a sharp direction change and moreover the duct is too wide. so instead of speeding up, the air spins and looses energy*

the further i go, the less i understand the concept of wide mouth blower fans

newest ducts are pointing down a lot more aggressively

[warm bane]

Wouldn't it make more sense to move the split to the right ?

Since the turbulences

Or are those not avoidable

[clever charm]

i put the split where i get about 50/50 for the split duct

[warm bane]

I think your cooling looks a lot like the Eva 3

[clever charm]

https://pkucmus.github.io/EVA/ you mean liks this? not really alike but the concept is the same, really long duct with broad smooth curves

[warm bane]

Yep

[clever charm]

that toolhead looks like it would have amazing com

[warm bane]

I mean most have a little mouth

Atleast on 5015s

[clever charm]

yeah true, but i don't dont think that there are many small mouth pwm 5015

nevermind there are, but at that price point might as well get a 5020

[warm bane]

Would it be bad to just close of a part of the fan?

It seems like it's sucking the air back in if I'm not wrong

[clever charm]

don't think so, it's what the a4t does

[tight ibex]

Section Analysis in fusion?

[clever charm]

yeah that would be a very clunky way of doing so, but i'd need to create a ton of sketches to do that too

[tight ibex]

Ahh i miss read, "along a path"

Maybe split body on the path?

[clever charm]

ideally i have a graph the gives me the cross section as a function of the distance along the centerline of the form

[green berry]

but I am

sip

[warm bane]

True

[clever charm]

wdym true

[warm bane]

He is

[clever charm]

for all we know he is a drunk mosterized racoon

[green berry]

also true

[warm bane]

I trust him more than you

Pspspspsps

[green berry]

always trust the raccoon

pepeevil

[warm bane]

Master Yoda if he was a racoon

[clever charm]

i do, apart for belt tension

[green berry]

https://tenor.com/view/sus-suspicious-sus-cat-suspicious-cat-cat-gif-13521542749286825758

[clever charm]

what helps is that bacon agrees with me so i feel not completey stupid

[warm bane]

I will design the worst toolhead

Just to make yours better

You don't know what steps I will take to make that happen

A 3x 4010 setup

[clever charm]

that's the latest one

[clever charm]

eh good luck on that, the bar is already very low

[warm bane]

Yk what

[green berry]

the bar is underground

[warm bane]

A 4x 4010 setup

Everyside

Gets one

[clever charm]

at least 4010 have a huge advantage

inertia

[green berry]

I can buy like 5L

You want monster?

[clever charm]

I won't say no

[warm bane]

And 2L vodka

[green berry]

always

can someone test the new hx711 driver fix?

it pisses me off

https://github.com/OpenCentauri/cosmos/pull/139

install this and do mesh 5 times

in a row

and also remove trsync hack

see if it errors

❤️

[clever charm]

gonna run another sim

[tropic gazelle]

@green berry i can test ist 😉 trsync hack????

[green berry]

Not trsync

Trsync seems to work

We have a new driver

For hx711

[tropic gazelle]

Hmm... I've currently got Cosmos 0.0.4 installed and have now run the mesh levelling process four times in advance without any issues. It's really strange how much user errors can vary.

[high sun]

I've been printing quite a lot recently and I'm using adaptive meshing before every print and I haven't had a failure since like 0.0.2 🤷

[noble mesa]

5020 is typically worse than 5015 because the RPM is usually lower. unless you are elegoo and just crank rpm to an unreasonable speed that prob wont last long

[clever charm]

makes sense.. larger diameter >>>> longer depth

[noble mesa]

like I still maintain that trying to dissipate 12W or 15 in the case of CC2 right around the bearings of a 5020 fan hub is a bad plan

[clever charm]

wdym? the high powered fan approach?

could that be why my 5020 died?

[noble mesa]

yeah I mean elegoo cracked the fan speed so high, too high IMO. like 5020s should not have the central spindle just crack like we have seen on some posts on reddit. means there is too much vibration and/or heat

main thing that kills fans is not the electronics its actually the bearings experiencing stress at high temps. so you start doing half an amp or more at 24v on those coils right around that bearing and bad things start happening.

and of course I highly doubt elegoo sprung for higher quality appropriately specced grease in those bearings

[clever charm]

now that's a massive improvement

[noble mesa]

like you probably want a thicker grease than usual given the high temperatures they will be running at

[clever charm]

think i still need to flatten the ducts a bit to avoid those eddies but hot damn that's a better

[clever charm]

@green berry would it be a good idea to reduce the outlet sizes a bit more?

each outlet is 35mm^2

looking at this i also need to reduce the intake thickness

[green berry]

Yes

[clever charm]

well that happened

Running again with a coarser mesh now

[obsidian aurora]

dumb question but this should work the stock hotend (and their lookalikes including the FlowTech hotend)?

[warm bane]

in the pictures we can assume yes

and videos

[clever charm]

Yeah it should support flowtech, and constellation. Idk about other mods, but I'm really not fond of those so I didn't bither

[obsidian aurora]

Sweet thanks for the info. I'm gonna look into printing this soon since I already cracked my stock shroud

[clever charm]

it's not perfect, but for the sake of my sanity i'll keep it there

ok nevermind

i want it to be better

[warm bane]

it never stops

[green berry]

Good enough

Ship it

[clever charm]

At least for now

Still tempted to do a small shape refinement while I work on other stuff and see what's better

Seems like there really only are small tweaks left to do

[warm bane]

thats ocd bro

[clever charm]

idk that's not amazing

the combined duct is too narrow and has a bump that causes issues

the rest is good

[warm bane]

i meannn since your 3d printing it there will be other issues also

[warm bane]

that seems like an relatively easy fix tho

if its only that

[clever charm]

yeah that's why i'm willing to do it, not eve sure if an additionnal sim is necessary

[warm bane]

i would still do it for the extra dopamine

[clever charm]

might just do it cause i have the process streamlined and it doesn't take more than 5 mins to setup now

[clever charm]

and also flex. i shat on someone for making a custom duct that was causing me thermal runaway issues and told him to do cfd. so i want to show those results on printables to back up my shit oning

[warm bane]

and also you can flex with it on your cv

[clever charm]

dw i do xD. my cello has probably gotten me my studies for next year. and also has opened a lot of doors for me. this will look nice next to it

also doing projects cause people that you have high regards of say that it's impossible just to prove them wrong is very satisfyinh

[clever charm]

weight reduction in a non floppy way

[green berry]

fillet hell

[clever charm]

yes

[clever charm]

wanna guess how many fillets operations there are?

[green berry]

46

counted them myself

[clever charm]

in my defense it looks a lot less bad without the edges

[clever charm]

5 xd

[green berry]

Eww

Too few

[clever charm]

i should add a big fillet on the front face

even though this really doesn't look amazing it will help a lot with stiffness

[warm bane]

porno

[warm bane]

porno

[clever charm]

nah this looks like shit

[warm bane]

wym

lol

[clever charm]

ok i'll make it more smooth, just to avoid a stress concentration

much better

i think 0.08mm layer heights will be a must

i expected way worse, with correct cooling settings this should be quite ok

also this will be by far the lightest toolhead cover

[high sun]

5020 bigly heavy?

[clever charm]

yep

half the weight of the total fanshroud was the fan for the 5020 version

[green berry]

make overhangs printables

set to 80deg

sip

[warm bane]

resin print it

[warm bane]

what did you change tho

[clever charm]

gonna play around with different settings but this seems promising

also ignore the lip, gotta fix that

spite is the best fuel

[warm bane]

sprite*

[noble mesa]

this is beautiful

[clever charm]

i made a pretty annoying mistake in the beginning...

[noble mesa]

ngl I might be switching to this

[warm bane]

buying an elegoo

[clever charm]

i assumed that the constellation extruder would have the same placement for the 3010 fan, but it doesn't. it's further out front, thus the weird cutout

[green berry]

that settings makes me the designer I am not

[clever charm]

if you do that, would you be willing to make a cooling shuriken with gamma, stock and the 5015 (whatever it's gonna be called)?

would love to have a real life comparison

[clever charm]

i wish i'm gonna reach this some time in the future, but not there yet

oh wait

[noble mesa]

soak q tip in acetone, put in a printed plug, insert into interior of duct

internal vapor smoothing

[clever charm]

oh was planning to print it out of paht-cf

[noble mesa]

honestly I might make a mod of this to bring the gamma magnetic coupling into this design

[green berry]

why paht

[green berry]

kinematic mount when?

sip

[noble mesa]

then it would be a fully incestious circle between our toolheads

[clever charm]

cause stiffness, also i'll anneal it first

[drifting tusk]

just do abs gf lol

good enuff

[green berry]

why do you need paht for a duct

lmao

[drifting tusk]

or pet gf annealed

[green berry]

I would've printed those out of petg

[high sun]

Is that 24 pin fully seated? 😂

[green berry]

I know someone that had same problem here

[lofty mortar]

Nah it's fine. Heatsink is HUGE and for Ai work loads it's limited to whatever the 5060ti can do + overhead

[clever charm]

you skipping over the 2 gpu's?

[green berry]

he never finished his thesis cause of that

🤣

[lofty mortar]

It stays quite cool

btw my asa heatsink bracket hasn't crept one bit yet

[drifting tusk]

need to cool that 7950x somehow

(it's the wrong way, I know 😭)

a good aircooler will do the same or even wipe the floor with that aio

[clever charm]

i've got a really weird image in my head now

thank you

[drifting tusk]

true, but I wasn't able to get a good aircooler for 40eur xd

also, technically both are air heaters

[noble mesa]

silver lining, he was the one difficult person I had to deal with (at least the most difficult one) so silver linings I guess? I am a terrible person

[lofty mortar]

Both the ram and the extra 5060ti I had are pure "ADHD impulsive action that the executives never cared to fix"the top card is a 5070ti

[drifting tusk]

my 5070ti is for my solidworks VM xd

[clever charm]

wtf

i run fusion on integrated graphics rn and literally can't tell

[drifting tusk]

solidworks needs a decent GPU for the rendering stuff and it must be nvidia cuz everything else just doesn't have support

[warm bane]

Holy

[drifting tusk]

40xx and 50xx cards also get faster denoising with the ai bs

I had opus decompile a full firmware dump of a certain product to C with my two company subs

[noble mesa]

was at a VC accellerator competition session today. I went to them a few years ago when I had a startup with my colleagues in grad school, but holy shit everything now is so saturated with AI in the dumbest boomer way

[lofty mortar]

I would but ares is locked down.

I'm setting this system ip because tldr the number one complaint is "NUH uh we're not sending data off to Claude it'll be in the ether"

Meanwhile passwords to critical equipment be on a sticky note

Compacted bowel?

no

[warm bane]

I mean for us impossible right?

(I hope)

[noble mesa]

I think my top choises are

[noble mesa]

possible if you are unlucky enough

[warm bane]

Mine is in a tank

Getting burned

Yummy

[clever charm]

ok so this might make the ducts printable

it's very scuffed

ok now were going places

a tiny bit more snip snip and then it's good

so all those fusion shitpost youtube shorts actually taught me something

[warm bane]

Time for you to make those shorts lol

[clever charm]

hell naw

ffs

that was supposed to be the one

[clever charm]

atom asked for it. more fillets

[clever charm]

@vernal harbor thank you, love this!

[vernal harbor]

This is pretty cool

god no

aaaand that's number 3

or even 4 i lost count

[noble mesa]

lol who were the others

like people say stealthburner looks like amogus

[clever charm]

eigenwert and someone on the elegoo server

btw don't ctrl+f amogus

pls rename the 5015 version amogusburner

that's an abuse of power

true but it's kinda funny

reducing the sim to the minimum necessary really speeds stuff up

do i even still have a say in the name or has that ship sailed?

lol of course you do

but I may still call it that ocassionally

[clever charm]

mhmmmm like every time you reference it ?

btw i really haven't decided or even thought about a name

[noble mesa]

lulz nah

[clever charm]

so if i don't find anything it might be

[noble mesa]

but I will keep that pin because its really funny

name it AADFD

an actually decent fan duct

[clever charm]

well it might be utter shit. only real testing will tell xD

[noble mesa]

well it will be better than the elegoo ducts for sure

[noble mesa]

honestly I'm not sure what se3d is working on v2

[clever charm]

oh ffs

[noble mesa]

at least his teaser looked very similar to the original

[clever charm]

i'm not confident enough at all in aeordynamics to tell you this xD
you can see that in how much the duct has evolved with the simulations

[noble mesa]

ngl a donkey with a mouse duct taped to its tail could do a better job than elegoo

[clever charm]

so that's a big improvement

that's the turbulent kinetic energy

https://www.simscale.com/workbench/?pid=2324055879412843329

idk if that link works gl

[noble mesa]

impressive and smooth increase in velocity

I'm glad I have some of these wide mouth 5015s already will print when you release

[clever charm]

yeah i think that's as far as i'm gonna reasonably go. that was really really really interesting

[clever charm]

yeah i'm still waiting to recieve mine and will repeat the same downforce testing with the different ducts i printed before

[noble mesa]

you should post this on subreddit, get your free spools

also this is the first viable solution to a nonelegoo fan. sure 2 pin fans are now an option, but without mosfet thats annoying even on cosmos,and bambu fans are widely available

[clever charm]

i'm terrible at social media, but i will kick myself until i do it

[green berry]

you just gotta be an alcohlic

that's the secret

[clever charm]

but i already am

[clever charm]

would you be willing to do some shuriken test with it? would be fun if this outperforms the 5020 fanmods out there

i would have liked to do one myself, but the sole reason i even went down this rabbithole is cause my fan is dead
