My settings are:
GRBL is 1.1h
GRBL in Laser Mode ($32=1).
The S-Max in LightBurn Matches $30 (which is 1000).
Power is set to 100% in LightBurn
My problem is:
When I disable laser mode ($32=0) it works as it is supposed to but when I enable it ($32= 1) it stops engraving (even though the laser turns on). So, if I increase the S-Max value to 3000 (even though it is $30=1000 in GRBL) it starts engraving again. I am having this problem only when $32=1. It seems like the pwm is somehow decreased in laser mode.
Please help me. I really love this software and don’t want to use any software.
