I need some help.
I’ve read the other posts and have made all the recommend adjustments, but I just can’t get the laser to fire when running a Gcode job.
Works just fine when I flip to manual mode - burns the test wood all day long.
I created the job in LightBurn.
I’ve set all the variables based on what I’ve read here, Tool Type PWM Spindle with Rapid Auto Off and Dynamic Power Off.
Verified LightBurn Basic Device settings is set to “enable Laser Fire Button” is green, (on)
General Light Burn settings (Gear) beinner mode is off, Better for Diode = Inches/min
The Device is a JTech laser Pro, is set as GRBL-M3 1.1e or earlier.
It may be telling that when I manual enter M3 S10 then press Play, on the manual code entry screen it also DOES NOT turn on the laser.
It’s as if the laser just never gets the commands.
I’ve even tried removing the laser extension cables, Still no luck.
Please help what am I missing?
