      This is for a mill so no Z probing. I can get 3 of these dirt cheap https://www.ia.omron.com/product/item/1017/
      and would like to use them on a new mill build. Here's my board info...

      I see info here https://duet3d.dozuki.com/Wiki/Connecting_a_Z_probe#Section_Mode_Num_5
      on how to connect as a Z probe but how do I hook them up for XYZ endstops?
      Thanks

        if you have a duet v1.04 you connect them like a npn probe
        https://duet3d.dozuki.com/Wiki/Connecting_a_Z_probe#Section_NPN_output_normally_open_inductive_or_capacitive_sensor
        but instead of connecting the signal wire to the z probe port you connect the signal wire to the stop pin for xyz

          Thanks for holding my hand on that one Veti. I have board v1.02 so I'll add in the diodes as well.

            Please confirm my wiring. My confidence is low☹

            Black sensor wire to Cathode(-) schottky bat43 diode, . Anode (+) side of bat43 to "stop" pin on endstop

            All stops are on the high end using NO switches

                Thank you Sir.
                Results are good. This switch repeats within .002 mm and that's probably in the mechanics. Perfect for milling application

                  @dc42 I want to use the same Omron switch above for endstops on my 6HC/SBC. 48v Vin. Duet is set to 5v ext (no jumper). Sensor draws 100mah. Voltage range is 5-24v.
                  Where should I get power for it and will it still require the diode?
