Duet2wifi with 3.01-RC5 making strange buzz sounds.
-
This should maybe have been put in Beta Firmware category, sorry about that.
-
What firmware version were you running before?
The buzzing sound is probably the PWM frequency. I suggest you reduce it to e.g. 10Hz using the Q parameter in the M950 command that creates the bed heater.

I went from release 2.05.1 -> 3.0 -> 3.01-RC5
tbh i did not test the bedheater when on 3.0, only the steppers. My bad. -

That explains it. In RRF 2.x the default PWM frequency for the bed heater is 10Hz. In RRF3 all heater outputs default to 250Hz.

The Q10 value made it go from an angry bee, to a slight clicking noise (Not sure if that is normal, but it is for my printer). thanks a bunch

@erwaly Duet hardware and wiring sounds like a good place.
