How to turn on PWM on 2.5 with gcode or m command??

I can see that sending M104 s255 turns on my heater at the extruder head, but I want to use a laser with PWM on 2.5.
I cannot find how to activate 2.5 (on and off). I find M106 and M107 and M1/2/3/4 and so on all over the place , but am at a loss on how to command line or gcode the PWm On and Off on 2.5, or any other PWM capable pin. Thanks for any help here, or direction to the page I cant seem to find :wink:

Check out the laser cutter guide on smoothieware’s website. I’m too new so can’t post a link, but it’s all there….I’m doing it on my laser as I type.
