I found this community while researching various topics related to my recent purchase of a cheap laser CNC machine running GRBL and thought it might be a good place to post about some strange behavior I’m seeing.
So for my setup I originally had it set to use $32=0 (disabling laser mode) which was the default. The side effect of this is when running the gcode generated by LaserWeb I end up with faint lines on the travel moves where it looks like the laser remains on.
I tried setting $32=1 to enable laser mode, and this removed the travel lines, however it had 2 unexpected additional effects on my test run (with laserweb laser fill path)
- The overall engraving appears less dark/black
- The overall engraving is deeper
These 2 additional effects seem contradictory so I’m hoping someone else has seen this and can shed some light on whats happening here :).
