That’s your controller telling you that you tried to move the X or Y axis out of bounds of the machine, and it stopped you from doing that instead of slamming into the rails.
I’ve looked up the machine and it appears to be a CNC, so most likely it’s meant to work in negative workspace. If it homes in the rear-right, you’ll need to set a workspace offset to move the origin to the front-left, which is basically the same as zeroing to the workpiece, except you’re zeroing to the entire work area of the laser instead.
The simplest way to do this is with a macro button in the console. Right click one of the macro buttons, then enter these commands:
G10 L2 P1 X-700 Y-700
$10=0
$32=1
And set the name to “Use Laser”. The first line offsets the zero so the origin is now front-left. The second line tells the controller to report position information relative to that zero point, and the third line enables laser mode in GRBL. After homing, click that macro button and things should just work after that. Let us know if you’re still having issues after this.
All of this is in our documentation here: https://lightburnsoftware.github.io/NewDocs/CommonGrblSetups.html
If you only have a week left in your trial because of this, post your trial ID here so we can extend it for you.
