BTT Smart Sensor v2 Constantly triggering Switch Sensor #55

Open deadpickle opened 2 months ago

deadpickle commented 2 months ago

I'm running the BTT smart Sensor v2 on a Voron 2.4 with klipper. When I print things seem to work correctly until some point where the switch sensor gets triggered. When I heat the hotend and extrude, without touching anything, the filament extrudes just fine, and I start the print. I then enter a spiral where the print will go for a time but then the switch sensor will trigger, stop, extrudes fine, and repeat. Is then sensor bad? Have I missed something?
