      Hello. I have looked over the forum and found referecndes of using encoders to track filament movement. I have found in my box an ecoder, is this:

      https://www.digikey.com/en/products/detail/broadcom-limited/HEDS-9701-E50/13401372?s=N4IgTCBcDaIBIFEAiBlAtATgOwAYCMaCArDiALoC%2BQA

      Can I use this encoder with my duet 3 to track filament movement and check if I have a jam or filament run out?

        @tinchus yes, assuming its connected to the same board as the extruder

        Owns various duet boards and is the main wiki maintainer for the Teamgloomy LPC/STM32 port of RRF. Assume I'm running whatever the latest beta/stable build is

          @jay_s_uk Yes, im planning to connect it to the same board.

          I have been trying to look for docs about how to do it since im not an electronic expert. On this encoder I have 4 pins, 1 is grnd, 1 is power input (5V?), and the other 2 is signal B and A. Im also looking for info on what pins on the duet 3 and gcode commands to configure, have not find this info yet, can you point me somewhere?
          Thanks in advance

            @tinchus one of the IO input pins should be fine. If it has A and B then it must have some sort of direction information.
            You'll just need to set it up as a pulse type sensor

              @jay_s_uk tahnks a lot for the input, seems I will be able to make it. Looking at the board: https://d3t0tbmlie281e.cloudfront.net/igi/duet3d/33DEuEJZXP16vLbF.huge

              If I choose for example IO_3 I can see there is a 5V_ext. This ecnoder says it uses a 5V input, So I the pin named 5V_ext is going to be the one I need to connect to the 5V pin of the encoder?
