Until after I updated the version to 9.24 I never had this problem so I suspect the software. Randomly when burning cups part way through the burn the Y axis will just start rotating wildly and then returns to a different spot on the cup and begins where it left off in the image. It also shifts the origin way off of the Y axis when this happens. If I re-upload the file again it usually corrects the problem but the cup is ruined. Anyone else see problems like this?
