I just installed the Lightburn demo version and have been trying to get it to work with my Shapeoko, GRBL v1.1f.
When trying to run a simple text test file, the machine runs as expected, but the laser does not fire. The laser will fire if I run the “Focus Test” command.
Also, it will not fire if I try entering G1 S## commands; M03 S## commands; Test Fire does not work;
$10 =0; $32=1; $30=1000 (matches spindle max in settings); Selected mm/min in settings;
I can exit Lightburn, start Universal GCODE and run laser with M03 command (laser is still functional).
What else should I review?
