Laser not cutting circles

Post by htrowrod »

I know there was a thread on this subject earlier, but that was actually for servo motors. I calibrated both x and y steppers. When I cut a 50.8 x 50.8 box it was 50.8mm inches on both sides, but when I try and cut a circle 50.8 mm it is 50mm in on area and the 51.2 in another and even 50.8 in another. It only messes up when both x and y motors are running at the same time. I also took that square and rotated it 45 degrees to make a diamond it was no longer a square.

I am using shielded wires for step and direction. I have both shields tied to together and hooked to chassis ground. should they be tied to power supply ground?

Thanks,
Bruce
