Problem with Skewed scans

Have a look at this thread and see if it fits your situation:

How do I fix skewed or slanted engraving?

This is an example of a fill followed by a cut around the letter A: [image] The fill is slanted, but the cut appears to be correct. If you have engraving that is slanting to one side, but cuts appear correctly, you likely have your motor pulse step polarity set incorrectly. On Ruida controllers, there’s a setting called ‘PWM Rising Edge Valid’ that you can change for each axis that tells the controller whether the rising edge or falling edge of a step pulse is what the motor driver is lookin…

Excessive acceleration can also cause the steppers to loose a step during direction change, but I would start with the link above.
