Voron 2.4 350mm LDO AWD Please send help lol

[charred kite]

please delete the pictures with the chamber heater. cover it via MS paint or whatever

this is agains the #rules

[lime swallow]

deleted it

[charred kite]

thanks. a picture from the front is still required, u can cover it up as i said

[charred kite]

we need to see the umbilical at the exhaust, thats why i wrote "cover" and not "cut it out" 😉

[charred kite]

i highly recommend to install proper strain relief on the toolhead.
if u keep it like that u can set a timer to when issues knock on your door. not good

[lime swallow]

Wouldn't this add more curves and strain to the wire?(from toolhead board plug towards the PUG mount?

[charred kite]

no because u adjust the cable so it makes a nice an loose S curve

[lime swallow]

Hopefully i have long enough cables will be printing it, would these help with graphs too?

[charred kite]

no but this is very basic knowledge to prevent headache

[charred kite]

did u manually sync motors by hand the first time after building, and now u are using the motor sync klipper addon BEFORE each single test? before each single print? before each single precise move? (brush etc.)

[lime swallow]

This is exactly what i did, when I finished assembly, I ran the motor sync macro first because i didn't understand how it was before( motor sync then tighten the grub screw i thought), when i found out I did the manual syncing first once posted ing LDO AWD github, then have been running motor sync now, ive tried both input shaping graphs with and without motor sync seems similar, but yes I have it added in my start macro so it will sync before printing starts

[charred kite]

Do one input shaper test with carto adxl please

[lime swallow]

Will do after printing this benchy, i think my settings are not fast though i only change accels but it doesnt go brrr like those youtube clips

[lime swallow]

I went with toolhead as per reth suggestion because carto reading is worse but will do it for comparison

[charred kite]

unfortunately this is totally the wrong place for "bbrrr" as we focus on basic help 🙂 Cube looks good so in this term there is nothing for us do to honestly. just trying to see if we can reduce the second peak on X

[lime swallow]

Is the first peak, the more focused one? I thought the first was the bad one

[charred kite]

hopefully u did read the first part of that message and made yourself very aware of what i wrote 😉
"second" was more like as counted, u have 2 peaks. but yes most likely the first one

[lime swallow]

Yup did read that thank you

[lime swallow]

doing adxl input shaping now

[charred kite]

thanks.
install one of the PUG mounts i linked. then rerun with toolhead.

[lime swallow]

alright will post an update once that is printed and installed

[charred kite]

I have seen u crossposted in #1407141831975763998 message multiple times, so that means we can close this post here to avoid crossposting?

[lime swallow]

Tried to delet thjs post, i thought i was able to but i guess not, please close this post, sorry for the inconvenience

[charred kite]

will do. Next time please decide for ONE place to avoid crossposting

[lime swallow]

can I reopen this?, @stable vortex ask me to remake a post but if its possible to just use this one?

@charred kite @stable vortex mentioned you might be able to help in my vibration profile?

[stable vortex]

@charred kite I am no bueno at setting up sensorless.
Can you lend a hand.
@lime swallow you can use this thread

[lime swallow]

For some reason, im still. Homing fine after tmc autotune

Im not sure why it sounds like this

[lime swallow]

@stable vortex I replaced my X beam to CF tube and Vitalii Live idlers

[mental sedge]

@lime swallow

• What panels do you have on?
• 6mm or 9mm belts?
• they look like stock GT2 and not EPDM correct? what belt tension?
• Motor type
  -Driver & Run current setting
• cnc XOL carriage mount?
• if not what plastic?
• what ADXL are you using? if its carto what V

[stable vortex]

@lime swallow the numbers you are getting look reasonable in the acceleration area. I think the vibrations are your motors

you might be able to improve the %vibr with adjustments to the umbilical

[lime swallow]

Structural panel - FR4 6mm
6mm GT2(not EPDM)
Motor- Nema 17 Siboor motors
Driver 2240 Running at 1.8a
CNC cartographer mount thats trimmed down to fit a4t
Using Lis2dw In my SHT 36 v3

[mental sedge]

look at the Y result closer, are you sure?

[lime swallow]

its actually confusing to me that I went CF tube for the grantry to be lighter and rigid to Improve Y but it improved X instead im confused

[lime swallow]

im comparing to other Y axis AWD and im not even close to them

[mental sedge]

"Using Lis2dw In my SHT 36 v3" toolhead ADXL is useless dont use it, noozle probe or a single board probe like beacon

[lime swallow]

I will rerun again in carto but it looks similar to these ones

[mental sedge]

you dont have actual structure panels either, FR4 is not doing anything here so its just a naked 2020 frame with gt 6mm belts

[stable vortex]

1.1 %vibr. It is likely due to peak2, peak2 is likely umbilical

[stable vortex]

I strongly disagree with your statement. Toolhead board is a preferred adxl to use

[stable vortex]

That main peak is actually y not z.

[lime swallow]

wasnt aware of this i thought it was rigid

[mental sedge]

failed to click that it was from the toolhead board so yeah fair

[stable vortex]

@mental sedge this is not an optimization channel. This is basic resonance.
Optimization can be handled in #unicorn_chasing

[mental sedge]

ok well we can agree to disagree

[stable vortex]

Feel free to have all the disagreements/discussions in #unicorn_chasing

[mental sedge]

@lime swallow asked for help on his printer and linked me here

[stable vortex]

@lime swallow this channel is just basic resonance help. It is not for optimizing.
With respect to awd the goal we set is 10k at 0 vibr% on ei. Anything over that is considered unicorn chasing

[mental sedge]

ok cool

anyway @lime swallow , you're basically where a naked 350mm frame and 6mm GT2 belts can take you, bigger belts, actual structural panels etc will be needed to get more out of your printer then what currently stands

[lime swallow]

@mental sedge

[lime swallow]

how do i get access to this channel?

[stable vortex]

Get a serial

[lime swallow]

ahhh When i got this I probably misread it I though this is stiffer and more rigid that aluminum panels

[lime swallow]

ahhh if I dis a bunch of mod in it would i still qualify for a serial?

[stable vortex]

You can still get a serial with a bunch of mods so long as the base is a voron

[lime swallow]

Thank you will try to get a different toolhead and post the results here too for your expertise

[viral wagon]

Your acceleration looks acceptable to me, that's more than double what I'm getting with my 2wd on X. Are you running 24 or 48v?

[lime swallow]

Just 24v, expectations for scaling was probably too high i really want high Y accels but most of the people I ask says this is normal awd 6mm belt performance any more and I would need to switch either gantry or 9mm

Once the toolhead that I want gets finalized and installed im hoping to get higher

Or maybe not but, i guess i should probably target lower cruise ratio and higher scv

[viral wagon]

Well, it all depends on how much money you want to throw at it..lol. I'll let you know what mine is like when I'm done with it, but it's probably going to be a couple months before it's running again.

I'm doing the LDO 6mm AWD, LDO speedy power motors, 48V with TMC5160s, vitalii live xy idlers, and dragon burner on my 350mm 2.4.

[lime swallow]

Oohh i see im curious if your accels would be different than mine if you go 48v and ldo motors curioua as to how much difference it will be, if it is I might try those motors too but im hesitant moving to 48v though dont wanna redo my electronics bay 😭

[viral wagon]

I'm excited to see how it performs. Just gonna take a long time, I don't get much play time unfortunately

[lime swallow]

Its better to take your time too though, did you order your awd kit already? Monolith might be just around the corner if you havent

[viral wagon]

I did. Got everything except the live idler kit, DB cnc mount, and my ebb36. Waiting on them to ship

[stable vortex]

You will get just as good performance with any awd gantry kit.

Performance wise they are all about the same +- a few hundred accel

[viral wagon]

This is kinda what I'm calling max performance for this machine. If I've still got a need for speed after these mods, I'm going to purpose build a machine for it with smaller print area and bigger extrusions

[lime swallow]

DB cnc mount also work with yavoth as well right?

[lime swallow]

now that i get to the point where im getting the norm AWD results, what other ways can I do to improve vibration profile? also to achieve higher scv?

[stable vortex]

As stated every awd gantry will get you about the same result.
Any modification to improve accels will work on any awd gantry.

Your biggest improvement to the vibrations profile will probably come from different motors

[lime swallow]

like switch to a different brand? i currently have siboor

[stable vortex]

LDO 2504 long shaft appear to be a good default motor for awd. I myself am using them. I would stay away from LDO kraken motors. They appear to be better in 2wd.

as for other types of motors I do not know

[lime swallow]

are you running 48v? also what good zones of speed are you getting with this motors?

[stable vortex]

This is on one of my AWD

[lime swallow]

why is symmetry low but you have a massive green zone?

[stable vortex]

I think it has to do with the motor sync

The print quality is good

[lime swallow]

i wonder if 48v also does this, it cleans the zones

[lime swallow]

this is also high speed? hahah mine dont look like that hahah

[stable vortex]

one sec I will get you the speeds/accels

[lime swallow]

what cruise ratio and scv is this?

[viral wagon]

No idea, I'm doing regular DB, and moving to RB when I decide on a uhf hotend

[lime swallow]

looking forward in your build wanna see how it looks 😄

[viral wagon]

Me too! I'll keep you updated. Maybe I'll start a build log if I can figure out how

[lime swallow]

make it go brrr
