Loud buzzing sound coming from toolhead
I am encountering a very loud metallic buzz coming from my toolhead but cannot find the cause or solution.
It is happening during constant motion and not direction changes so not related to acceleration.
It does not appear to be a resonance issue in my opinion because it is the same frequency of sound coming from motion in both x and y direction and after changing the mass of the toolhead (switched from BLTouch to Klicky and even tested with partially disassembled toolhead).
Input shaping also has not corrected this problem.
The volume does change with loosening/tightening belt but it is still the same frequency.
My best guess is that the cause is somewhere else but the vibration is traveling down the belt either from or to the toolhead.
Will post a video shortly.
