Walt530 ( project won’t center)

Are you ever moving the head of the laser by hand after homing? If so, this is likely the cause of the issue as your machine will no longer have correct knowledge of position.
If you’re not moving it by hand then can you provide the following:
1. Overview of your workflow and what you’re doing.
2. Full screenshot of LightBurn with your design loaded and ready to burn. Please have Cut and Laser windows showing.
