Shake&Tune's vibrations profile has a lot of information, and I'm not really sure what I am looking at. So some help interpreting the graphs and improving them would be great. I do understand there are a lot of bad speed peaks, but I'm not sure how to fix that. I am happy to provide additional information. Thanks!

Can you change your tmc_autotune pwm to 20e3 or 22e3 please and rerun the test

The vibrations profile test

Ok here is the graph with pwm at 20e3. Sry about the double post.

can you reduce your microsteps to 32

coral night Mar 20, 2025, 3:45 PM

#

And run the test again?

Here's another one with 32microsteps it doesn't look to different

go back to 128 micro steps
but decrease current to 0.7
Want to see if that will decrease the graph we are seeing in angular speed energy profile

Motors at 0.7A and back to 128 micro steps

#

leave it here

#

still does not look great, but your vibrations are lower

#

have you made interpolate to true

coral night Mar 20, 2025, 5:55 PM

#

Yes interpolate is true since I'm using autotune

#

Is this a mechanical issue or just the motors resonance. I'm curious for the future if I getting long shaft steppers or changing my mechanics would help this.

#

looks like motor issue

#

you can try commenting out the pwm and see if it has changed based upon the change in run_current

coral night Mar 20, 2025, 11:05 PM

#

Commented it out and it looks worse. So I'll just stick with what I had. Maybe I'll upgrade to Monolith with better steppers sooner than I was planning. Thanks for the help!

play around with the settings we have been adjusting. Maybe reduce run_current some more - say 0.65. You want to print in the green zone for the global speed energy profile

#

Ok if I get any major changes I'll post them here.

thank, happy prinrinting

I was messing around with settings and I tried increasing the current to 0.9A and then 1A and I think it improved the angular speed energy profile. So I was wondering what you thought about that. Also if I'm printing over 200mm/s should I be increasing the range of the graph to include higher speeds?

you can run this test faster than 200 mm/s. However, always start at zero.
Also, if you do run this test over 200 always make sure you also run it from 0-200, then run it from 0-xxx. This is because sometimes noise will hide in the 0-200 range
