PWM Frequency for bed heater
-
is it possible to change the pwm frequency of the bed heater to 20Hz?
-
@paboman I know it is possible to adjust the PWM frequency for the heated bed because @dc42 proposed it to me as part of another question. He just did not mention how to do it.
Just looked it up and you can use
M307 H0 ... Fnnn(https://duet3d.dozuki.com/Wiki/Gcode?revisionid=HEAD#Section_M307_Set_or_report_heating_process_parameters).Manuel
Duet 3 6HC (v0.6) with RPi 4B on a custom Cartesian
with probably always latest firmware/DWC (incl. betas or self-compiled)

thank you, I will try -
@paboman @wilriker the bed heater is not really any different for the other heaters. In hardware it is different because there is provision for significantly higher current. In firmware there are legacy commands that refer directly to the bed heater (Like M140) but as far as things like PWM vs bang bang its the same as the extruders - M307...
