Louder noise/resonance on U axis
-
I am having this issue on my IDEX printer where the u-axis for the second extruder is significantly louder compared to the x-axis. There seemed to be more vibrations when moving causing the extruder to resonance with it
I tried a couple of things but it doesn't seem to improve the situation:- switching the driver of U axis
- switching the stepper motor
- enabling/disabling interpolation
- change to 256 microstep
Here is my config.g, I made sure the configuration for both x and u axis are the same (except for 256 microstep on u axis currently):

Is the motor louder or the belt/pulley combo? (2GT and GT2 standards are not exactly the same )
Does the belt rub somewhere (against the idler pulleys)?
