It’s a problem with Lightburn and the F1 with Rotary!!!
I have done everything according to the instructions.
Laser cutting or engraving is possible!
But not the preview with the frame!
Is there a video in which you can see and follow the steps one by one?
I have already tried several times, with new installations.
What do I have to enter EVERYTHING in the Gcode start and end?
There is and is no preview possible.
