@Phaedrux Hi, I've resolved it. It turns out one of the wires on the connector wasn't making a connection 😧
Sorry for wasting your time and thnx for your help and patience! 👍
Edit: So I tried going back to PWM5 since that's the one I would like to use and that is indeed not working. (well only on startup for some reason). Not a big issue thouh. However I would've liked to have the bed level sensor plugged into the most left PWM.
