@fcwilt thanks for the suggestion, I was hoping for a simple solution, unfortunatly that didn't work, it just didn't detect the sensor at all.

@dc42 thanks for the assist, looks like I need a new switch. Any recommendations?

I'm using the Duet3D filament monitor: Rotating magnet runout sensor with the optional switch trigger. The problem is the switch I'm using is closed when there is no filament and the config is expecting it to be open. Below is my sensor config, is there some code I can add to change closed for open?
