      Is there a way to adjust the PWM frequency for the hotend heater(H1) in the reprap config.g? It makes an annoying relatively loud buzzing noise when it is active that immediately stops when I turn off the heater. I think it's just resonating with my enclosure and making it especially loud in my situation.

      Using a Duet 2 wifi, reprap v2.0.4

          @Veti Perfecto, that's exactly what I was looking for. For some reason I couldn't find it for the life of me, probably just used the wrong search terms. Thanks for the quick response.

              @Veti Probably not a bad idea, frankly I haven't had any insurmountable problems with the FW I'm on so I never really felt the need.
