      A ripple of 1V p-p is unlikely to matter.

      I agree.

      Is there any drawback for the Duet with the highest PWM frequencies (CPU/resource usage wise) besides a tiny bit more power consumed by the mosfet?

      Just a little more heat dissipation in the mosfet, and perhaps slightly poorer resolution in the PWM setting.
