Laserweb4, grbl on Arduino Uno w/ motor shield. The laser doesn’t fire during raster engraving. What do?
Only on raster? Did you add specific settings on LW for GrBL? Info on that here http://www.cncpro.co
Yes, only raster, it fires with vector cuts just fine. Another member set up the board. I’ll see.
You need to manually add M3 or M4 to the start of your g-code, or put it in the start section of LW4’s settings.
