Rank beginner here, I’m sure my issue is not new, but my searching hasn’t found the answer.
I have a Comgrow Z1 grbl machine.
Every time I try to send a job to the laser, the machine moves to the home position at the upper right, trips a limit switch, and stops.
This machine is also a router. I had the same issue when using the router head, and stopped that by removing the autohome (G28) command from the gcode file.
I can’t figure out where I would do the same in LaserGRBL or Lightburn.
