Problems with PWM Heater-Pins
-
Hi,
When I disable the Heater-Pin as such and try to use it as PWM Pin, the duty cycle does not drop from 100% to 0% when I try S255 vs S0. If I invert the logic trough a I in the G-code, the duty cycle goes from 0% to 10% (rough value estimated from the oscilloscope data). I tested this behaviour for several Heater-Pins.
Is there anyone familiar with this problem?Greeting, Kakadu31.

Did you specify the PWM frequency? If so, what frequency did you specify?
Which firmware version are you using?

Hey thx for your answer. I did not specify the Frequency, I was not even aware of the possibility. I used RepRapFirmware 1.21

@kakadu31 have a look at the M106 documentation:
https://duet3d.dozuki.com/Wiki/Gcode#Section_M106_Fan_On
It shows how to set the frequency etc.That said you should expect the defaults to work properly in most normal situations.
