      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 😉
