Alright @LifeOfBrian my friend, I’ve got an update for ya!
Here’s what I did:
-
I changed the µsteps count to 64 for X, Y & Z axes
-
I installed & set up Klipper TMC Autotune, seems to be working fine although I don’t really know if it’s doing anything outside of shwoing up on the “Vibrations Calibration” profiles
-
I re-tuned input shaping to account for the new micro step values which gave me slighly higher frequency and acceleration values.
-
I did a re-run of the Vibrations Calibration profiles. Here are the results for X & Y:
-
I reduced the print speed of the model to 94 mm/s to print “as fast” as I could whilst still being inside the second “safe zone” provided from the vibration profiles.
Overall, the printer appears to be running much quieter and the print came out much smoother. The pattern is still visible in the Y-Direction but at a much lesser capacity than what it was before. I’m gessuing this probably means I need to reduce my print speed closer to the 80-90 mm/s range to move further away from the “upper limit” of zone 2.
So far this seems to be the right approach to fixing the issue, but I guess I’m just a little dissapointed at the fact that I upgraded to Klipper primarily to be able to push for higher printing speeds, but it won’t be a huge improvement from the stock model of the Anycubic Mega Pro if I have to stick to the 80-90 mm/s print speed range… But I guess it’s just a limitation of the hardware/bed slinger profile on this thing.
I think what I’ll attempt next is to change the heavy glass stock ultrabase to a magnetic PEI sheet to further reduce the weight of the bed and retune input shaping. Hopefully that’ll allow me to push for slightly higher speeds.
I also noticed on your project’s Github page that you’re upgrading your machine to linear rails. Keen to hear what your experience was with this. Do you think it’s a worthwhile update and if so, which linear rails/manufacturer did you use for your setup?
Open to hearing any additional feedback you may have at this stage!
