What version of LightBurn, and what version of Carbide Motion? I am on LightBurn 0.9.14 and Carbide Motion 513 and don’t have any new problems, but I have only been using the laser for a few weeks. I might have solved the problem when setting it up initially. I added two extra commands to my “Use Laser” and “Use CNC” macro buttons to toggle GRBL laser mode ($32) and to set the GRBL status mask ($10). The laser mode has to be set right if you want to laser raster images (it turns off movement pauses when the router speed (the laser intensity) changes. I think the GRBL status mask being set incorrectly was preventing jogging in Carbide Motion.
My “Use Laser” macro button runs:
$10=0
$32=1
G10 L2 P1 X-812 Y-812
My “Use CNC” macro button runs:
G10 L2 P1 X0 Y0
$10=255
$32=0
The X and Y numbers on the G10 line for “Use Laser” will vary depending on what size Shapeoko you have. @AutomatedBrad might be having the same problem as you, I noticed he had a question like this one yesterday but I didn’t have a chance to test and look up my settings till this evening.
