      Hello from Italy.

      Last month I purchase a genuine IR Probe and connected to one DuetWifi.
      Initially, it seemed to work well, three days after it stop working. 4 Blinking led when starting, then nothing.

      From the electronic scheme I checked every individual components and solders, everything seems to work correctly except the infrared emitter most distant from the capacitor. At this terminals I have 1.2 volts but no voltage drop on resistor, it does not absorb any current.
      With my IR checker I only find one working IR emitter. Is it faulty?

      I have been waiting for a response from customer service for two weeks.

      many thanks
      Daniele

        Yes it sounds faulty to me. Did you buy it direct from duet3d.com, or elsewhere?

          No, makerdise.
          It say that " it behaves like you did create a short on the backside of it. What happened to the cable on the left side in the video - it looks like it isn't attached to the connector. Did you use a crimp tool? The bolts you use for fixing are 2 big. "

          The signal pin (white) in this video was extracted during removal. The screws are the ones in the box.

            Please tell Makerdise that I approve replacement of that IR sensor under warranty.

                @dc42 @pedrinid - Ok, we will send out a new as a replacement, it doesn't make sense to return the old as the shipping costs are to high.
