Laser not burning with Gcode

LightBurn Hardware Compatibility Ortur Lasers
1

Just received an Ortur laser master 2, OLF 1.37,grbl 1.1f.

I have been able to use LaserGrbl to burn some wood creations but I would like to use Lightburn. Using lightburn I can get the laser to burn using the fire button. However, when running any gcode, it moves the laser and turns on the laser but does not burn. Below are my configs and a gcode file. Any help would be appreciated.

You’re using inches / minute for speed. 1000 inches/min is 423 mm/sec, or roughly the speed I use when engraving with my 60w CO2 system.

Your machine is rate limited to 110 mm/sec, so you’re getting about 1/4 the output power you asked for since the machine can’t move that fast.

I would recommend changing your settings to this:

Then re-entering the ‘1000’ again, so it’s in mm/min, not inches/min. You can probably go up to 3000 to 4500 mm/min.

Thank you. I skipped past that. Changing it and resetting solved the problem. Going to buy my license right now. This is an awesome program. Thanks again.
