I have recently setup my CO2 laser temporarily with GRBL (waiting for smoothieboard to be shipped) and I have a problem I fail to see its cause.
Everything works just fine exept it cuts everything exactly 0,5mm bigger… I setup my steppers correctly, I tell it to move 1mm it moves 1mm etc… imported DXF has proper size… BUT when I cut it its 0,5mm bigger than its supposed to be… Did enyone delt with simmilar problem? (no its not caused by width of the laser beam)
Yes offcourse I could compensate it either by editting steppers or dxf to match the exact size of the cut but thats crude solution.
ps: Many thanks to devs for lightburn, i have got thru many laser softwares and this one is really amazing.
