The PWM fan does not turn off on my Duet. I have tried the following:

M107
M106 S0
Restarting the board

The LED for the PWM fans is always on no matter which GCodes I send.

Please specify which version of the Duet you have and which version of the firmware you are running. If the firmware reports the board type in the M115 command, check that it has identified the board version correctly. Also, confirm that you have the fan connected to the FAN0 pins.

Board is 0.8.5

Fan is on FAN0. I also have two additional fans on the Always On pins. The LED light by the PWM pins is always on.

You are running the original RRP 1.09 firmware, which doesn't support the Duet 0.8.5. Try upgrading to my 1.10+4 release or to chrishamm's latest.
