I have the CloudRay MP-60 with a SL-1064-200-290 Lens and Lightburn Software Version 1.6.03. I have uploaded the Cor file Marker Pro(LM23A0518JZ)/software/Cor/F290.cor When trying to cut a 20mm circle art piece, the resulting measurements are: x-axis = 19.76mm y-axis = 20.48mm Ideas or help is much appreciated. ![MP60 SETTINGS](https://us1.discourse-cdn.com/flex020/uploads/cloudray/original/1X/1f654412292e43eb0c5b915679873617737fe7b2.jpeg) ---

The calibration tool is Lightburn works, but I seem to have to recalibrate often. I should not have to be recalibrating constantly. It is most noticeable on circles.
