      @omni, if it's a pulse generating sensor, does option #7 here work? https://duet3d.dozuki.com/Wiki/Gcode#Section_M591_Configure_filament_sensing

      (you will also need to specify pulses per millimeter, the Duet input you are using, and the extruder it relates to)

        Thanks for the answer.
        I've tried it yesterday - but it seems that Duet is not recording any data from the sensor.

        I configured the sensor as following, just to log data when printing :

        M591 D0 P7 C"^e0stop" L0.07853981634 R90:110 E3 S0

        but it did not receive any data.

        Any ideas on what I can try is highly appreciated.

        Thanks again

            @eight_heads lemme answer before he gets online 😄 (he's not very active on forum 😄 ). it works on his board, the config does not need pullup and need much bigger values as it is low res

            so something like

            M591 D0 P7 C"e0stop" L7 R50:200 E15 S0

              @arhi do you test it on your board?
              I want to buy the same sensor you did.

                  @eight_heads I just used @arhi config and tested the BTT Smart Filament sensor on my Duet WIFI - Seems to be working perfectly!

                      Mine worked well for a while and then started to give false warnings and stops (under extrusion), and now it does not work at all. I guess that maybe the spring holding the wheel got loose and it's not rotating enough while the filament is passing, but haven't opened it yet to check....
