Wrapping up building Ratrig VCore3. Have everything running pretty good but having issue with filament sensor.
Board is SKR Pro 1.2 and sensor is the BTT SFS V1.0 Smart Filament Sensor. I have it wired to the port E0 as shown in the attached photo. In the Klipper config file i cannot seem to figure out what to use for the switch pin. See that section of config below. Can somebody help me determine what pin to put in the config and also share how you figure this out in case i run into it with other pins? Thanks!
