[umbral bronze]

Bruh are you actually arguing against trinamic???

[knotty estuary]

alright

[knotty estuary]

no

im just saying watterotts are mediocre

[umbral bronze]

You are

[umbral bronze]

Because you are not using the proper things in your config

[knotty estuary]

in my head nothing is adding up

[random estuary]

.110 is generally used on 2209s cuz it maxes the run current at 1.78 which is within spec for 2209
.075 is generally used on 5160 stepsticks cuz it limits to round 3.2A
.033 is on externals usually because it limits to higher like afaik 6A

[knotty estuary]

stepsticks handle 3A max, my board is rated for 2A, how can i be drawing 4A?

[random estuary]

youre probably not

driver is likely limiting it to the driver max but klipper is just confused af

[knotty estuary]

thats what im trying to say

[random estuary]

board is porbably just not ideal past 2A

what rsense are you running on what drivers lmfao

[knotty estuary]

0.35, thats what came stock in tycho config

[random estuary]

what in the absolute hell

on what drivers?

[knotty estuary]

watterott 5160s

[random estuary]

higher the sense resistor, higher the max allowable current but lower the precision at low currents

[random estuary]

my guy ur running ur motors on 3.2ish amps

klipper is just confused cuz you have wildly wrong sense resistro

not even like

[knotty estuary]

alright man

thanks

[random estuary]

cloise to correct

[knotty estuary]

for the help

ill change it

oh fuck it is at 0.075

i just remembered wrong

i think 0.035 is for externals?

[umbral bronze]

https://tenor.com/view/blinking-eyes-white-guy-blinking-meme-what-huh-gif-26334323

[umbral bronze]

.033

[knotty estuary]

close enough

[random estuary]

.033 yeah usually

sense resistor effectively just regulates current and makes sure klipper and the stepstick are in agreement

[knotty estuary]

well in that case, they are overheating for a seperate reason

[random estuary]

how many amps you running

[knotty estuary]

2

2004s

[random estuary]

mine didnt overheat on 2.5A without heatsinks or cooling

[knotty estuary]

i have heatsinks on mine

they overheated at 1.5A

[random estuary]

tf

what was the error

[knotty estuary]

Prolly because of the speed of mosfet switching

[knotty estuary]

tmc ovetemp

[umbral bronze]

But, I mean there is nothing in my wiring that can be wrong it is the connector that can only go in the proper way, the + (red) the - (blue) and the 4 stepper wires, even if those are fucked it will not burn the drivers

[random estuary]

was it tmc overtemp or was it a load of nonsense and then tmc overtemp

[knotty estuary]

no

might also be important to know i was running 2m/s

[random estuary]

dis what i mean by a load of garbage + overtemp

[knotty estuary]

nope

and it was actually hot

[random estuary]

do they overheat running lower speeds at same or higher current?

[knotty estuary]

didnt test

[random estuary]

i think ive only gone to 1.6m/s on watterotts

[knotty estuary]

they seem fine at 600mm/s

[knotty estuary]

ive tried 2.5m/s lol

[random estuary]

i didnt do that for long when i was testing 2.6

[knotty estuary]

the 2004s have so much inertia to torque ratio

[umbral bronze]

The mellow 5160's are waaay worse in terms of temperature, they absolutely NEED active cooling or they go overtemp

[knotty estuary]

its crazy

[random estuary]

yea is kinda unfortunate

[knotty estuary]

well yeah its because of the mosfets

watterott uses high efficiency mosfets

[umbral bronze]

It's very expected tho

[random estuary]

could just be like you said with the switching rate

[random estuary]

mmhm

[umbral bronze]

Also properly specced and qyality ones

[knotty estuary]

mhm

im running 128ms and too

[knotty estuary]

mellow is properly specced and “quality”

[umbral bronze]

Lol no

[knotty estuary]

they are just different efficiencies

[random estuary]

LOL

mellow is not quality

[knotty estuary]

yeah i changed that bit 😅

[umbral bronze]

Mellow electronics are the furthest thing from quality

[knotty estuary]

better than btt

[umbral bronze]

Eh

[random estuary]

depends

[umbral bronze]

Debatable

[knotty estuary]

the btt 5160s are shit

[umbral bronze]

Which ones?

[random estuary]

do you want a board that catches fire during firmware flashing or catches fire randomly

[knotty estuary]

too many people compare $10 btts to $25 watterotts

[random estuary]

agreed

the btts dump heat

[knotty estuary]

you get what you pay for tbh

[random estuary]

barely managed 2.4A with btt

and active cooling

[knotty estuary]

my 5160s are semi actively cooled

with a bit of airflow they can stay under 50c

without it it goes to hell

im gonna measure pulses with an oscilloscope soon though, i have a sneaking suspicion that somethings wrong

[random estuary]

ill eventually swap some of my watterotts back into my trident and see if i can managed 2m/s w out problems

[knotty estuary]

failure mode is odd

[knotty estuary]

yeah 2m/s is pretty easy on bigger printers

i just dont think that watterott is day/night

[random estuary]

theyre mainly reliably not crap

[knotty estuary]

yeah

[random estuary]

btt were reliably meh

my big5160s are just random lil mfs that have given me about 12 different errors

[umbral bronze]

I've done 2m/s on my vz with my cursed setup, I don't see why you couldn't

[knotty estuary]

i can also do 200k but 205k and it shats its pants

[random estuary]

oh i can

although tbf my trident is heavy af

[knotty estuary]

^this is 2000/40k

200 scv

[knotty estuary]

my entire moved mass is under 180 grams lol

but 2004s suck for this

[random estuary]

my moving mass is around 1kg

[knotty estuary]

yeah but speedies

[random estuary]

youre not just running out of mcu and its dying weird?

[knotty estuary]

no

[random estuary]

2k 128ms on 4 motors is tight

[knotty estuary]

i have a blackpill

[random estuary]

yea thats tight

[knotty estuary]

i changed to 16 ms since then

it runs fine

[umbral bronze]

I might be popping the mcu off the mellow board and onto the corevus once alpha testing is finished

[knotty estuary]

this failure mode is rotor lagging behind

mcu would throw a klipper error

you can see it sometimes catches up but gets worse

curious to see is results though

[umbral bronze]

Get some hollow 8mm shaft steppers to replace them

[random estuary]

Sir that’s just skipping steps

[umbral bronze]

Yeah

[knotty estuary]

yeah, but its skipping because of the rotor

you can hear it

[random estuary]

It’s skipping because it’s out of torque

That’s what skips sound like at stupid speeds

[tulip vessel]

It's I think 3A or 3.1

[random estuary]

Yeah 3.1 seems resonable

[knotty estuary]

https://github.com/CoconutDevelopment/CocobustorZero

new updates pushed

[misty trench]

[tulip vessel]

So it doesn't melt?

[knotty estuary]

wdym

[tulip vessel]

Curious why u added a couple for m4

[knotty estuary]

its double shear

no cantilevered pulleys

[tulip vessel]

Isn't it double shear to begin with?

Wait no it's not.

[knotty estuary]

no

[tulip vessel]

Did u break a motor with it....

[knotty estuary]

nah

just qol

[tacit oyster]

thicc

[knotty estuary]

new stuff

hiwin xy, cnc rail

and cpap finally

currently revising all my parts

[wheat briar]

That extruder still looks ridiculous to me so large on such a tiny printer lol

[knotty estuary]

https://vxtwitter.com/Siboor3dprinter/status/1724317951233564708

[tacit oyster]

yooo

less go

[knotty estuary]

Haha yeah

[knotty estuary]

Whered you find this?

I was gonna work with siboor initially but i asked formbot

[misty trench]

ask ldo

jokes aside

full kit?

[knotty estuary]

yep

[misty trench]

oooh nice

[tacit oyster]

Commetss

[lucid pulsar]

[peak mango]

What the heck u doing to this pour creature now

[wet raft]

please don't bend your bowden tube that sharply 😔

[knotty estuary]

[tacit oyster]

Don't burn down ur house just yet

[knotty estuary]

Lmao

Its all good i got the fuse in

[tacit oyster]

Who said I won't come to ur house and remove it

[knotty estuary]

[tacit oyster]

lock ur doors

im outside

[tardy sphinx]

that's amateur... I've been here since the beginning, I'm in your walls

[knotty estuary]

there are 4 people apparently in my walls now

hope you guys arent being squished

[misty trench]

its pretty hot here

mind turning on the ac

[knotty estuary]

sorry man

i forgot

will do

[misty trench]

thanks coco

[tacit oyster]

ok uh

im now in ur closet

bro you have no variaty

whys there damn spools of filament in here

and like random stuff

[wet raft]

Tiny and cute heating pad

Ferocious heat

[knotty estuary]

xy rebild done and everything back together

[misty trench]

paint the motor red

to make it faster

[knotty estuary]

Good idea

With fire and racing stripes

[misty trench]

Yes

[tardy sphinx]

Put "NASCAR" in letters for extra turbo boost

[knotty estuary]

mm ac mains

[tacit oyster]

🔥🔥🔥

[misty trench]

fire

[umbral bronze]

@knotty estuary what is your max accel you've done at 2m/s?

[knotty estuary]

40k

[umbral bronze]

what steppers? 2001s?

[lucid pulsar]

theres 2001s?

[knotty estuary]

2004s

[umbral bronze]

ok

I did 55k on my 235 but with 2804's

[knotty estuary]

cool

[umbral bronze]

idk if 2804's or 2504's would be better for you

[knotty estuary]

2504s

2804s are pretty useless for most apps tbh

majority

[umbral bronze]

but less VFA

so like kinda useless but also kinda useful

[knotty estuary]

just run 32ms with interpolation lol

[umbral bronze]

do you run interpolation?

I think I am running 256 ms rn

or it might still be at 16 idk

[knotty estuary]

128 interpolated

[umbral bronze]

does it even increase performance or is it just for accuracy?

[knotty estuary]

It does

[pearl marsh]

Well fuck lol

I mean if you built it to break records sure 3k is fine

Its not sane imho but I can see why one would full send the budget

term of build volume its a teacup as my other reference to that

I could not print hardly anything on that except brackets and minatures most likely

The stuff I build requires full volume

I don't like gluing parts togethere if I can help it

and I got a 3D printer mostly for making usable parts and also making cases and possibly assist with drone parts + gliders other RC things

[knotty estuary]

all my parts fit on a v0

its for rapid prototyping of parts

[pearl marsh]

I see

Parts for building Vorons lol

thats its use case haha

half the frame built in like 2hres

I still want to see it actually print that fast

a lot of core xys can move fast

but can it print faster than 300mms

[knotty estuary]

its abs so

[pearl marsh]

yeah ok

that thing isnt fucking around lol

Its a fun exprimental v0 that is for sure

I can't justify it in my mind but I mean it exists

so congragts job well done

[knotty estuary]

haha

[pearl marsh]

I am fairly content with average speeds

more conered on quality of parts

and volume

You break a record with that v0?>

I would expect thats why it exists

[knotty estuary]

well i have a 1/10th of my fans on and its open air abs

i trigger trp if i enable more fan

its undergoing upgrades now

[pearl marsh]

its faster than the100?

[knotty estuary]

yes

and im running 2004s

[pearl marsh]

Means nothing to me

see that is why I said I not equipped to go full send on DIY

from something totally unique

with no buyable part list

[knotty estuary]

lol

[pearl marsh]

packed for me

[knotty estuary]

make your own list

its fun

[misty trench]

start with a "normal" voron kit

[pearl marsh]

I could but I have this 50ft wing span glider project im working on

with lidar

and solar

Coz I am tired of using a controller lol

I want to use the PC and throw this fucker off a roof

and let it go across two cities

180+km apart

LOL

[knotty estuary]

if i started with a kit i would legit be left with frame and screws lol

[pearl marsh]

full autonomouos glider is what I want to build

for surveying

[misty trench]

because you are an odd one

maybe not even frame

[pearl marsh]

coz it would fall apart

or you would take all shit out of it

[pearl marsh]

I mean tbh just give me th9e frame too

I really could probably do my own build

with a frame

and PSU and board

Its not that much mroe cplicate

[misty trench]

only rail speed holes

[knotty estuary]

i did that

[pearl marsh]

if u give me the the belts frame and all that shit

to make it move

I can figure out the hotend and drivers and toher shit

myself

and motors

[knotty estuary]

thats the hard bit imo

[pearl marsh]

I just cant be arsed with the moving part

I want the frame there and me just source the actual head

and guts

that run it

If I can have that I can build a core XY

I just do't know really know much about the movement train of them yet

to really build it scratch

and figure out the frame and rails and belts

and the whole motion of frame carriage

[misty trench]

build a trident

ez way to learn imo

many docs on that

[pearl marsh]

worth the $

I am open to it as I do want a CoreXY that cartesian I have now is leaving me with a lot to be desired

I just cant justify more $ into a 2019 cartisian printer

that we shall say retrofitted

with klipper and modern parts

and a few nice to haves of modern frames

That was my first printer its been a fun project I still re design it from time to time

But sinking money outside of stuff I can 3d print and and build off from is not really in the cards for that printer

Perhaps a better enclosure the guts moved outside is about as best it will get

CoreXY are more valuable to actually spend $ on making incrasingly better

is the gist of what I see over the internet and here

[pearl marsh]

is that what u actually did

oh while im in here..

Is it worth putting fans on back of my motors ?

Or does it do fuck all

[knotty estuary]

no haha

i just heatsink my motors because i run them hard

[pearl marsh]

That is what I am asking since I need to put my board into an enclosure with a 120mm fan anyway

I was thinking how muych harder would it be to use some of the 12 fucking fan ports

to add fans to the motors

[knotty estuary]

wagos

[pearl marsh]

is it even worth putting a fan

on the tool board and the X motor

and maybe the Y motor

its cartesian

its not going too hard

[knotty estuary]

depends

[pearl marsh]

but would it actively do anything worth it coz I have HEAPS of normal sized fans

enough to actually do it

[knotty estuary]

i run my components at their max rating so thats why they are there

[pearl marsh]

I am using .900 on the X

and .500 on the Z

well under max ratings

extruder is 1.0 I tink

let me check

[knotty estuary]

im running 2.0 lol

2004s

[pearl marsh]

yeah

I am not really asking a lot from them

Also not sure if these values are sane

I think they are OK but not sure if could be improved or how so

Toolboards driver has a little heatsink

all of them have heatsinks

inc the CB1 computer has a heatsink

wait OMG

I am in a project channel

so sorry bro thought I was in the regular spam channel

[tacit oyster]

wait thats all u need from uart?

damn

im stupid

[pearl marsh]

Yeap

Unless you want to use diag pin for sensorless homing

stealthchop ###### you can search from a browser and get info even on Klipper has info on this different numbers for the stealthchop mode the most common is the one I use

@tacit oyster Setting "spreadCycle" vs "stealthChop" Mode¶
By default, Klipper places the TMC drivers in "spreadCycle" mode. If the driver supports "stealthChop" then it can be enabled by adding stealthchop_threshold: 999999 to the TMC config section.

In general, spreadCycle mode provides greater torque and greater positional accuracy than stealthChop mode. However, stealthChop mode may produce significantly lower audible noise on some printers.

Tests comparing modes have shown an increased "positional lag" of around 75% of a full-step during constant velocity moves when using stealthChop mode (for example, on a printer with 40mm rotation_distance and 200 steps_per_rotation, position deviation of constant speed moves increased by ~0.150mm). However, this "delay in obtaining the requested position" may not manifest as a significant print defect and one may prefer the quieter behavior of stealthChop mode.

It is recommended to always use "spreadCycle" mode (by not specifying stealthchop_threshold) or to always use "stealthChop" mode (by setting stealthchop_threshold to 999999). Unfortunately, the drivers often produce poor and confusing results if the mode changes while the motor is at a non-zero velocity.

[tacit oyster]

kk

[pearl marsh]

I have yet to try using without quiet motors, I suspect non stealthchop is needed for faster tight tolerences

[narrow lotus]

emf

[craggy seal]

I think dirt build up would be a worse issue

[narrow lotus]

probably not good either

[knotty estuary]

i know it was a joke

Oh you can't get laser cut parts, forgot about that

[misty trench]

why no laser cut?

you know youre pushing for speed when you put holes in your linear rails and blocks

[tacit oyster]

dayum

chonky

[umbral bronze]

That's way too restrictive fyi

Probably won't even get half of what you could

But it does look great

[umbral bronze]

Please don't give him the idea of putting holes in the blocks, he might actually do it

[cinder edge]

No plz

[umbral bronze]

I know, it's stupid

It ruins all the preload and just makes the block useless

[cinder edge]

I think hollowing rails would too

[umbral bronze]

Speed holes often are actually anti-rigidity holes

[umbral bronze]

By not removing material where the balls slide it is mostly fine

[cinder edge]

Ig

[umbral bronze]

Also, it is a speed benchy machine, he doesn't care that much about quality

His speed benchys will still look like shit

[cinder edge]

But what's the point

If it's just crap quality, why

[umbral bronze]

I don't get it either but it is still impressive

[pearl marsh]

Fastest benchy ?

[lucid pulsar]

iirc hes aiming for sub 2 benchy

[misty trench]

@knotty estuary

[knotty estuary]

yes sub 2

SHES ALIVE

[stuck patio]

sub 2 minute time!!??

[knotty estuary]

the side fins help actually

[stuck patio]

really?

glad it worked out!

[tacit oyster]

That's bigger than ur bed lmao

[pearl marsh]

I am asking how fast does it print one now

[proud wraith]

i need this part cooling for my printer

idk a 5015 is just not enough

i was thinking liquid nitrogen, but this seems more doable

[knotty estuary]

im 99% sure it is lol

and ln2 is not feasible in the slightest

[proud wraith]

like even at 200mm/s i can see some cooling issues

i tried a dual 5015 duct but not sure why the fans spin slower than just a single one

and thus worse cooling

idk is it the mosfet thats limiting the current?

was it just toasting under the cover?

[misty trench]

@knotty estuary yk if siboor will ever release their v0.2 thing?

[vital moth]

Ask them tomorrow

[misty trench]

ye

[lucid pulsar]

ln2 but its the boiled cloud not the liquid

or maybe a fine mist

carburetor

[tacit oyster]

@knotty estuary

[stuck patio]

oh dame

[misty trench]

at that point just let the toolhead float

[stuck patio]

lol no, the tension GT2 belts are on traditional 3D printers is so low it will probably just sag lmao.

[misty trench]

double shear it and tension to gates spec

[stuck patio]

doenst prevent the fact that belts are inherintelly elastic.

[misty trench]

magnets!

[stuck patio]

no actually, input shaper might just be able to compensate.

[misty trench]

dont give coco ideas

[stuck patio]

@knotty estuary ideaaaa timeeeee!

[stuck patio]

gates spec for precision movements to be specific!

[misty trench]

[stuck patio]

[tacit oyster]

nice

[tacit oyster]

any iupdates

i want fastest benchy

[knotty estuary]

ill be swapping on 2504s on the 8th

[tacit oyster]

🔫 do it fast

[pearl marsh]

@knotty estuary what material do you normally print these parts out for the printer frame and hotend etc

[knotty estuary]

Asa

[pearl marsh]

I just thinking is ASA good enough or should I switch to something better

ah

thanks

[knotty estuary]

Im switching to cf asa though

For some bits asa isnt enough

[pearl marsh]

that is what I already use

ASA CF

on my shroud

[knotty estuary]

Dope

[pearl marsh]

but I printed it sub par heating wise

I imagine strength is not peak

due my chamber temp does not really exceed 50c

I can't anyway or the toolboard will explode

I am planning on perhaps rectifying this situation

as I printed an ABS control box

and I have slowely in my mind been planning out some way to go to local hardware and pick up steel faraming for making box frames

and grab some high accrylic

[knotty estuary]

Getting rid of can?

[pearl marsh]

and just begin marking a custom box with proper cut outs for fume mitigation and and under tray

If I want to print ABS at proper strenght I have n choice

not unless I can actively cool the CAN board

in a way it stays out of the pure hot air

60c can kill it

ambiant heat

Some people said it was useless when I chmaber but I disafree

see I can have the control box

and the EBB

the EBB is just an extentsion of the contorl board

making cabling less of a hassle

Should Iw ant to say mount the EBB to outside of chamber up on the wall of it or something

That way I only I can wire wire a loom from closer to the printer

Honestly I am not sure

I might just ditch it

[knotty estuary]

I like my pcb

Its basically as convenient as can

[pearl marsh]

yeah I need something that will do a similar job as CAN

but just not have a MCU lol

that does nto care about heat

pretty sure I can get thsoe and thy just plug into a ribbon

then I can just map GPIO pins on my manta M8P

and send thru a ribbon connector or something

I dunno I have just been thinking about making a better chamber

so I have one as thenI have choices

I can move the electornics out of printer air

I can put in proper controlled heating and ducting

and filter

and if I ever wanted to re use it I can

on say a voron

etc

It wont be super expensive either

about cost of a beginner printer to prob put together

[knotty estuary]

Yeah pcb harness

Like stealthburner pcb
