Rotation Calibration
1. Check the steps per rotation value in the Rotary Setup window of Lightburn on your control
computer with the engraver on.
For certain engravers, this parameter could be mm per rotation, this manual uses steps per
rotation for example.
For this OMTech Fiber laser engraver, use 12800 directly.
2. Stick some masking tape, one piece on the chuck as close to the mounting as possible, and the
other piece on the mounting. Make sure the chuck is free to rotate.
