Question Re Spindle PWM

[rvalotta]

Is it possible to have 2 different spindle PWM outs? 1 for a spindle and 1 for a laser? Where it switches based on $32 or something similar? Thinking of adding a laser diode to the gantry so i can engrave my logo or something similar.

Yes.

Where it switches based on $32 or something similar?

Easiest would be to switch using a custom M-code (or $32), either to control a relay or switch between PWM generators. Both can be done from a plugin. Here is an example for how switching by swapping function pointers is done by trapping $32.

If you switch often and have setting stored in flash then $32 will add to flash wear.
