4028 PWM not working
So I wired my Delta 4028 fan as shown in the 4028 guide with red to the top fan pin at 12v, black to PB11 heater pin, and the PWM pin to the FAN0 PA8 pin. I can turn the fan on and off fine, but while on it is always at 100% no matter what I set it to on mainsail. I tried the 25khz and 100hz cycle but neither worked. Is there possibly something wrong with my FAN0 pin or is it possibly something else?
