FAN rpm DWC same value all the time.

[matej1006]

Hello

i have problem if i don't have diode before exp.pb6 number go crazy when i start homing printer.
If i have diode installed then rpm is always 1500 and i can run noctua fans at 50% pwm or 100% pwm.
i add even 10K resistor between PWM signal and 5V.And is still same

PWM work's fine
