I have this incredibly loud noise coming from my Y-axis. It doesn’t affect print quality, but it is horrible to listen to and really loud. It is present when the Y-axis moves at ~100mm/s and gets worse/louder as speed increases.
How can I mitigate this? There doesn’t seem to be any mechanical issues when I move the bed by hand, it is smooth and easy to move.
I’ve tried putting a hand on the stepper, it doesn’t really reduce the noise. Its a bit hard to keep a hand on the bed when it’s moving at high speeds though. I’ll see what I can make work.
Pretty sure it’s some sort of motor vibration that hits a resonance frequency in the frame/chassis/bed of the printer.
