      I cannot get my NPN sensor to select active low logic level for the Z probe I have followed the instruction
      NPN output normally-open inductive or capacitive sensor

      and I have connected the silicon diode anode of the diode to the E0 STP pin

      when I plug it in the indicator light is off and in machine properties, the endstop hit is showing yes on drive 3 when there is nothing ner but no when I touch the sensor

      Here is my endstop Settings

      [[language]]
      ; Endstops

        1. You need to use I1 (uppercase-letter-i followed by 1) not |1 (vertical-bar 1) as you appear to have done.

        2. Some users have found that they need to use a Schottky diode, not a normal silicon diode.
