Control Laser using J19 Pin 3 (PWM) ?
Hi All,
Seen some people online that added a laser to their Prusa Mk3.
Some of them use one of the PWM-Pins that normally control the extruder fan.
Just wanted to ask the question if there is any reason not to use J19 Pin 3 (Einsy Pin 2):
Laser would be powered by the printer‘s PSU ans switched on/off using gcode „M42 P2 S255“.
I‘m really new to all this stuff, so any thoughts are much appreciated:-)
