I have started playing with lightburn, after running a test file with some G code setup for the Avid EX controller I have an issue. After the file runs, instead of the laser going up in Z travel to return to X0Y0, it goes down. I see this in the G code file.

S0  
G53 Z-6 F100 ;goto safe height  
G0 X0Y0

Is this my issue? Its moving Z to -6

Thanks in Advance

I took out the G53 move like below and it moves up now.

G0 Z0.8 F100 ;goto safe height  
G0 X0Y0

Yep, LB is pretty easy to edit for what you want before and after the main Gcode.
