Hi,
I have a lowrider V4 on a mesa 7i96s controller and DM542 drivers. When I run any of the axis I get these small random jitter sounds once in a while. I was thinking the might be a grounding problem, but I grounded digital GND to motor power GND and the PSU earth ground. No change. I’ve tried different PSU, different microstepping. I’m now at a bit at a loss what this can be. Anyone here have ideas?
I wanted to add a video with sound so you can hear it but videos and links are not allowed..
