I just tried LB with cutting square on paper on K40 laser, with Arduino UNO and GRBL.
The laser is working and cutting except on each angles. (I have the same issue if I try to cut a circle. The cut is not closed)
I imported a dxf file, I also tried to draw a square, circle and polygon with LightBurn but each time it’s the same issue. Cuts are not closed.
I think that 1 parameter is not correct but, even if I search it, I don’t know which parameter is on default.
Could you help me?
Thank you by advance.
