gcode [MSG:Pgm End]

LightBurn Software Questions
1

Hello,
A small problem that appeared a few weeks after I bought my laser (Lightburn trial period): the gcode [MSG:Pgm End] is systematically sent to my cutter and the head of the cutter moves towards Ymax and this forces the motors (no end of stroke in yMax and XMax).
When I disconnect the USB connection, the problem disappears.
How can I remove this gcode?
If anyone has an explanation, I’d be grateful!
Nico

When you power up the machine, the only GCode Lightburn might send is $H, which is the command to Home.

For this to happen, 2 things must be right:

  1. GRBL parameter $22 must =1. This says you have limit switches.
  2. Auto-home on startup in the Device Settings window must be turned on.

If you do not have limit switches, both should be off or zero. If you do have them and the laser goes in the wrong direction, that is a different problem with the parameter settings.
