Continuing the discussion from Test Fire Power Won't Pass 20%:
When I set up the cut and change the Power Max (%) field, the power stays constant (and very low) regardless of the field. In addition, if the Power Max (%) = 100, the laser only turns on at the corners of the cuts.
I have tested the laser with my own direct input and it is capable of reaching full power so something between grbl and the laser is decreasing it. Any idea what that is?
