Admittedly I’ve never used Lightburn before, so maybe there’s an option I need to set yet?Īny help you guys have would be very appreciated! I’m not sure what I’m missing at this point. Basically everything seems to work, except the laser doesn’t turn on. I drew a small circle on the screen and hit the Start button. Connected it to the MPCNC and verified it connects.
Configured it to use Marlin FW, set the commands to Inline, added M3 I to the start GCODE (and M5 to the end). Different values for S*** vary the laser power as expected, so all of this should be working.Īfter the successful test I installed a trial of lightburn. The laser turns on and burns a small scorch in the test piece of wood I have below it. I got my laser wired up to PIN44 and have tested it with M42 P44 S128. I’m currently using the 515 version dual endstop firmware with a RAMPS 1.4 board. Hopefully you know what I’ve done wrong at this point.
I’m so close at finally getting this all working (I think).
