 1. Ensure the sensor is plugged into an endstop port. Please refer to your MCU pinout to identify the pin you are using. 
 1. Set your endstop pin as a pull-up (put a `^` before the pin).
 1. Ensure that the reverse bowden is contiguous all the way from the toolhead to the sensor. Any open/unconstrained filament will cause it to false detect
-1. Sensorless homing/StallGuard is known to interfere with the sensor if the diag pin is set on the MCU where the filament sensor is connected.
+1. Sensorless homing/StallGuard is known to interfere with the sensor if the diag pin is set on the corresponding endstop pin. For example, if the diag pin is enabled/installed for stepper driver in position 3 then endstop position 3 will not allow the filament sensor to be detected properly.
 1. When starting klipper you should disable the filament sensor. This prevents it from tripping while you're just loading filament, doing testing or maintenance, etc. It should then be enabled in `PRINT_START` and then disabled again in `PRINT_END` and `PRINT_CANCEL` Example config below.
 1. **(Optional but recomended)** Take it entirely apart and lubricate everything especially the little wheel that sits in front of the sensor. The grease that comes with the sensor is not the best and can cause the filament to slide on the bearings instead of rotating them which is needed to drive the sensing wheel. **DO NOT allow any of the lubricant to get in/on the filament path as that will cause the filament to slip on the bearings and not drive them.**
 1. **(Optional but recomended)** Shim the interior so it can only move back and forth. Using small strips of paper is enough to shim. You may need to fold them several times to fill the gap. See picture bellow.
