... I'm using Marlin4Due with some of my laser-engravers/cuters with a modified Pronterface-variant, called "gieCAPS"
(here some threads about)
All of my drivers (laser, pastedispensing, CNC) are modified to work with pulses - but not common PWM, but the speed-synchronous extruder-steps.
So with "G0" moves the machine moves without, "G1" moves with laser pulsing ... the power is set by pulse-length and "pulses per mm" or the "E"-value in the G-code ...
