Rotary Smashes Start of image

Has anyone had this issue?

If your rotary has any backlash at all, that direction change will expose it - the slack needs to be taken up before the cup will move, so the first few lines get engraved over top of each other.

I had this same problem yesterday. 2 things I discovered: 1. wheels next to motor were no centered on the wheels at the other end. 2.

When put the origin at the beginning of the design so the tumbler did not need t move to start- it was OK.
