LightBurn v2.0.00-RC4 Release Candidate

So, if “fire laser” is ticked, then the behavior is now as expected… Because it turns on your main engraving laser as you jog/frame… And the command used (M3) will disable the crosshairs in the firmware. Previously we were probably sending M4 which we know from this thread was not. I’ll check with the folks who implemented this previously what the expectation there is… But I suspect that yes, we do want to change it back to M4.
