Laser works in manual mode, won't fire when processing Gcode

Accessories J Tech Laser
10

Update for my situation:

  1. I can actually burn using lightburn output either GRBL or GRBL 1.1 output, but could still not turn laser on using the M3 S10 strategy - meaning can’t accurately locate the images to be etched.
  2. The mode selector does cause laser to fire (at 100%).
  3. However, based on The M3 S10 XY problem - #2 by rblur01, if I turn machine off at the control box, turn it back on, but make sure to cancel the homing upon startup, the M3 S10 does indeed fire the laser at low power. This not homing trick seems to work for me. Might be worth trying for others who run into this.
