Frequently Asked Questions

Why is the P argument ignored in the M106 command?

Simple AF implemented support for the P argument into the python code in our klipper and klipper-rpi fork to mitigate performance issues.

Unfortunately until recently the installer for Simple AF for RPi was not ensuring that the p_selector_map was being set on the [fan] config in order to eanble this feature. We have recently updated the installer to ensure the p_selector_map gets added to the fan definition.

So if your M106 P1/M106 P2/M106 P3 commands are not working as expected, please ensure you have updated to latest Simple AF!

Warning

You must replace any M106 P0 references with just M106 as P0 is not supported to reference the part fan. In order to mitigate performance issues that were causing klipper to crash with a move queue overflow we had to migrate from [fan_generic part] to [fan] for the part fan.
