Corners Not Cutting Correctly

What version of GRBL do you use? GRBL-LPC has parameters that let you tune the lower end of the power ramp so you can “pull it up” to where a high power tube ionizes. I’m not certain 1.1f has this - it wasn’t really meant for high power lasers. The alternative would be to use the GRBL-M3 driver, which doesn’t use power ramping.

I want to reorganize my GRBL GCode generator to allow these to be used by the same device, but the way it’s set up right now, the M4 based generator assumes “laser mode” is on, and the M3 generator does not. If I decouple those, you’d be able to use M3 for cutting and M4 for marking.
