All right,so i've set up my laser to cut a 50x50 mm square.

The final result is 40x40 mm square. 20% less than it's set up in LaserCut53.

The laser is a g weike 3040, and i'm not able to connect to it via USB for now. All jobs are produced as .mol files to usb memory.

Anyone have any ideas what might cause this?
