I have a Sculpfun S9 laser and it only moves in a straight line when framing and running. It’s almost like it’s cutting in the ZY plane.

One of the diagnostic steps you can take is swapping the X-axis motor and the Y axis motor cables at the controller board. This can help identify the difference between stuck motors and mechanisms or a problem with the wiring or control board. I am not expecting z-axis support on a Sculpfun S9. T…
