no idea what I'm doing

[sour ember]

I have absolutely no idea how to read these graphs other than it's out of the good zone.

For reference, I couldn't figure out how to get the sound app belt turning to work, I printed the GT2 belt tensioner thing and used it but I apparently didn't use it correctly either.

No mods other than Chaotic lab tap

350mm 2.4 r2 rev d built from the fabreeko LDO kit. Only mods are chaotic lab tap, titanium backers, and rapido hotend.

✅ The front of the machine with good lighting
✅ Visible exhaust cover
✅ Front idlers
✅ XY Joints
✅ X & Y + belt measurement picture/result - generated via Shaketune (https://github.com/Frix-x/klippain-shaketune) is preferred

✅ List of all relevant mods and options
Chaotic Lab Tap
Titanium Backers
Rapdio hotend

✅ Printer Family & Size:
350mm Voron Trident 2.4 r2 Rev D

✅ Which ADXL was used (adxl345, Lis2dw, etc.), and where it is mounted
ADXL345 built into the nitehawk PCB board inside the stealthburner

[halcyon willow]

could u please provide the remaining things which are mentioned in the posting guidelines?

[sour ember]

Sorry, I missed the adxl question, went through and made my post easier for clarification and answered that one

if I missed anything else let me know but I think I got it all

[halcyon willow]

still some things missing, please read them again and doublecheck what u posted

to give a hint - 2 shaketune generated pictures are missing 🙂

[sour ember]

X & Y + belt measurement picture/result is that 3 different things? I have zero idea what I'm doing with shaketune

[halcyon willow]

yes 3 different things, hence the & and + 🙂

[sour ember]

Sorry, I feel so stupid with all this lol..

These are the outputs I can get from shaketune.. which ones do you need?

axes map?

[halcyon willow]

all good. this https://github.com/Frix-x/klippain-shaketune/blob/main/docs/macros/axes_shaper_calibrations.md one

[halcyon willow]

also where is the screw?

[halcyon willow]

and check your XY joint screws according to the picture

[sour ember]

uhhh good question, I vaguely remember thinking it was weird that there wasn't supposed to be a screw there when building, but now that you mention it I should go double check that

[thin tree]

@halcyon willow I just started scrolling and it looks like we identified the same things 🙂

[thin tree]

@sour ember can you provide a picture of the entire front of the printer please

[thin tree]

Which version of cl tap are you using

[sour ember]

V2

[sour ember]

trying to run through all these as fast as I can 🙂 thanks guys

[sour ember]

I tightened the chain at the tool head is this any better? No idea what to do about the back

[sour ember]

Ohhhhh

[thin tree]

Rerun input shaper please

[thin tree]

Can you remeasure your belts

[sour ember]

as far as the shake tune calibration or using the GT2 printed tool measurement or what?

[thin tree]

the belts measure both belts. Preferably with the PF tension tool

[sour ember]

That's the tool I have I'll go measure one sec

[thin tree]

yup that tool

[sour ember]

ok it was way too high, like 3 or maybe over. tuned it back to 1.9 and going to re-run the shakes

[halcyon willow]

tuned it back to 1.9
if u play with the belt tension make sure to slowly move the toolhead around by hand or do a G28 - once done verify u get the same reading again on the tension tool

and dont forget to do a G28 + QGL before each measurement.

[sour ember]

I haven't been doing QGL.. let me do that and rerun stuff

[halcyon willow]

Do that from now on as well as a G28 before 👍

Always verify your work

This is telling me to loosen a by 1/4 turn

[sour ember]

new ones after QGL

loosening and re-running

maybe a bit more?

[thin tree]

Did you derack when you first put the gantry on?

[sour ember]

yep, though I've done a lot since then, might have knocked something loose or something.

[thin tree]

Your belt graphs can be casued by the following issues:

1. belt alignment
2. belt path
3. belt wear
4. bearings/idlers

[sour ember]

Ok sorry about the delay, I did a full tear down and rebuild of the gantry, double checking all the alignment paths and stuff.. here' s my new results:

prints are actually looking really good, I just have layer shifts still (which is the original reason they sent me over here.. x and y shifts in seemingly equal distances)

[thin tree]

Can you provide and updated picture of printer and a picture of the layer shifts noting which direction please

[sour ember]

Yep! Here's the layer shift, that big tall part is supposed to be on the first rectangle, so I shifted over all the way to the other.. Seemingly perfectly diagonal back and right, or close to it

I'll go grab new photos of the printer in a few

[sour ember]

If this helps at all, just had the layer shift on a print that I think shows it more clearly

Almost a perfect diagonal soft back and right

[halcyon willow]

This channel is not meant to be used for printing help in terms of layershift, EM or PA wrong.
We focus on resonance.

So best would be to set this post on Hold until u figured out what caused this.
Either post in #1169405960540917810 or #voron_2_discussion as I suspect a mechanical issue

[sour ember]

Yep I totally see your point... Sorry about that

[halcyon willow]

All good. We can keep this open as long as u update us once solved 👍

[halcyon willow]

Also make sure to click on your flag in #rules

[sour ember]

Done!

[halcyon willow]

Have u solved the layer shift so we can continue/start with analyzing the new fresh graphs?

[sour ember]

Layer shift solved, then toolhead board caught fire, replaced, and now one of my z motors is skipping steps and I'm in the middle of fixing that.. one thing after another lol

Probably need to get that sorted before we do resonance 😦

[sour ember]

OK @halcyon willow got all my mechanical issues solved I think, completed an 11 hour print with no issues. Here's my new charts, they look a lot better to my untrained eye lol.

[halcyon willow]

im sorry it seems like your message didnt got to me.
could u post us fresh graphs and print a VORON cube with 3 walls, 5 top bottom and no infill please? post pictures with good lighting of all 4 sides

[sour ember]

No worries! I've got like 10 hours left on a print ATM but I'll do thst as soon as I'm done !

[halcyon willow]

sounds good.

[sour ember]

update: didn't forget about this just keep running into issues with the extruder stopping extruding half way through a print consistently. I'll update when I can

[thin tree]

Check extruder motor crimps/wires

[halcyon willow]

have u seen Reth's reply above? did that help?

[halcyon willow]

pinging u again for the reply above ^
