While cutting through a 1/4 inch thick cherry wood sheet, I noticed that the XRF is distorting the shape of all circles that I cut. The cuts come out somewhat oval and not circular. These are cuts on flat 10” x 24” wood sheets, not on cylindrical materials like tumblers. In the hobby CNC world, it’s not uncommon to have mis-shaped circular cuts. These are usually due to backlash in the linear motion components. I didn’t think that would be an issue with the XRF, since it uses tensioned belts. Anyone have an ideas on what’s happening and how to fix it? I’ll post some pics of the circles tomorrow. Thanks

Please check if your axis calibration is accurate by following these steps:
- Cut a square on your material (for example, a 50 x 50 cm square). Measure the actual length of the width and height with a ruler.
- If the measured dimensions differ from 50 cm, go to Machine Settings in LightBurn and click the Calibrate Axis.
- Enter the distance values. LightBurn will automatically calculate and update the correct step length for you.
- Repeating this process a few times will result in much higher precision.
