I just replaced the board on my Creality CR-10 with a 32-bit SKR Mini E3 V2.0 control board that runs Marlin 2.0. With the new control board, the printer's Y-Axis moves vibrate so much that it blurs the camera I am using that is connected to the bed.

I have checked the mechanical stuff and it seems like the issue is the stepper motors are running choppily instead of smoothly.

I know that 32-bit Marlin has lots of things I can tweak. Are there settings I should be checking? Where do I start?

    $\begingroup$ Are you sure you're just not using different acceleration/jerk limits than with the original board's firmware build? $\endgroup$

  • $\begingroup$ I'm using the Marlin defaults for both. However, the choppiness happens even during long straight moves (like homing) so I don't think it is a jerk/acceleration issue. $\endgroup$

  • $\begingroup$ Do you have video/audio showing the issue? I'm not sure I understand what "choppiness" means here. $\endgroup$

  • $\begingroup$ I mean that the Steppers aren't rotating at a steady speed. It seems as they are stepping, stopping, stepping, stopping creating a very choppy movement of the axis. You can feel the studdering by hand and it is painfully obvious through the picam.. (With the steppers off, the mechanism is perfectly smooth) $\endgroup$

  • $\begingroup$ Did you do anything odd with the microstepping configuration? $\endgroup$

The problem turned out to be mechanical. The arm that I mounted the camera on had developed a crack where it connects to the build platform. I used some superglue to repair the crack and the camera shaking went away.

The lesson here is to check EVERYTHING mechanical before trying to blame shaking on the firmware.
