Ring on my hand ring on my print
I have been battling ringing for some time now. I have calibrate the voron cube so it would be ideal in regards to input shaper, flow, offset, belt tension, PA, temperature, speed, accel etc.
I tried the adxl with the kit, adxl in ebb42 sideways mounted. Today I even tried the ls2dw usb nozzle input shaper.
I changed the real notor muhts to accommodate FMMM.
Ringing is still there. The results are from different input shapers and the difference is nigh, considering one was mzv for x , Second ei for x.
Y is ei both sides and this one is solid (it seems).
Input shaper is working but terribly bad. I Mean, nozzle adxl it the most precise unit of measurement of vibrations and this damn chunk of metal and plastic defies all odds and spits out shit.
Speeds : from turtle to racecar. From 50 to 230. Higher speed eliminates VFA , ringing there.
Accel: the higher the better, against all recommendations but still does not help.
I have tried to replace the motor mounts. Idlers are kinda okay, but I noticed belt rubbing on one side. Belt was dead on when I put an additional spacer to the right lower furthest idler. Worse results , better belt path. Reverted to original spacing.
During input shaper left side of X vibrates and gives off trembling sounds. Belt tension does not help. Higher, lower, still the same.
Oh yeah, frame dead 90°. I forgot how many times I rechecked.
Printer on solid ground. All wires near the head clamped to the best extent as to not vibrate and provide better input shaping.
Mzv, ei, zv. Better results with ei.
What trivial things I did miss?

As far as trivial things go, have you made sure that one of the grub screws on each timing pulley is tightened against the flat side of the stepper motor shaft and that all grub screws are tight? Otherwise I would suggest posting your input sharper graphs in #fix-my-resonance.
Hmmmm, yeah. These are incorrect. Will Adjust. Also i have found the shaper itself was incorrect due to my ebb42 side mount which vibrates and gave bad results
