      Re: [Duet Wifi with Bi-Directional Logic Level Converter](Optical End Stops)
      Hi, I have recently bought Duet 3d WiFi V1.04 and have at home 5 pcs. Omron EE-SX 671(NPN) and 5 pcs. Omron EE-SX 671R(PNP) optical sensors. I have found this post and its clear how to connect them for end stops X,Y and Z for my delta printer. Question is can I use them for Z probe and if so how do I wire them?
      Here is link with data shet for them

      Thank You, Toni

        You should be able to follow the instructions here assuming the part number in the title is correct and your sensor is PNP.

            Can someone please check this scheme that I made and confirm is this wiring correct to use?
            I have checked optical sensor Omron EE-SX671 with external supply at 5V and multimeter I have. There is no connection between sensor GND and OUT with power applied, but when blocking sensor diode light I have short between GND and OUT (approx 3-5 Ohm measuring between pins), thus OUT becomes GND and that routing to Z probe input.

              That looks correct to me.

                That looks correct to me.

                Thank You for helping me to be sure before wiring.
                Just one more thing , is it ok to put diode 1N4001 at wire from sensor Out to Z_Probe_IN or it is not needed?
                Thx,
                Toni
