      I have searched for a while but cannot find how to connect the DC42 IR probe when the expansion header is used for the duex5. Anyone point me in the right direction?

      Edit :
      After more searching I am lead to believe I can just connect to the Z probe input. That is my current setup. With this setup I get 2 flashes on startup, and the Z-probe reading on the web interface is always hovering around 457. It never changes. When I get something close to the sensor, the red led will light but still says around 457. Acting like a trigger.

      ; Z-Probe
      M558 P1 X0 Y0 Z1 H3 F150 T500 R0 ; Set Z probe type to unmodulated and the dive height + speeds
      G31 P500 X-22 Y-1.5 Z2.5 ; Set Z probe trigger value, offset and trigger height
      M557 X15:570 Y15:570 S100 ; Define mesh grid

      (sorry, cannot edit category, should be IR)

      Thanks
      Ed.

        IR probe doesn't use the 50 pin expansion header.

        How do you have it connected? Photo?

          From the fitting instructions at https://miscsolutions.wordpress.com/mini-height-sensor-board/:

          Duet 0.8.5 and Duet WiFi electronics: wire the sensor to the 4-pin PROBE connector. The OUT pin on the sensor should be connected to the AD12 or IN pin on the probe connector. Leave the AD14 or PC10 or MOD pin on the probe connector unconnected.

            Alright, my bad. For as much as I had looked at the connection diagram, I never really noticed the Z-probe connection. My brain seems to only see the Z End stop. Sorta working ATM.

            Does not seem very linear, or is it even supposed to?
            Once it get close it jumps to around 465. Move up in small increments it will jump to 535, its triggered but does not go beyond that.

              That is expected behaviour, see the fitting instructions page.
