      Is this the product you try to connect? https://github.com/bigtreetech/smart-filament-detection-module/blob/master/manual/smart filament sensor module manual191205.pdf

      It works also on 3.3V (good), has GND, power and signal wires, and the 'break interface' sounds as an on/off output. In Duet's terminology, this sounds a 'filament run-out sensor' (not to be confused with a 'filament monitor').

        @zapta Thanks for the answer.

        Yes, that is the product. I have already connected the wiring to the E0 stop properly (+3V, Signal, GND) - but I have seen on the other post (here) that another user has been having problems in setting it in firmware.... it's a pulse sensor it has a rotary encoder (I don't know if it's an optical or magnet one, haven't disassembled it completely). That is why I was asking if anyone had success in setting it up properly...

          @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

              @omni any luck? I have one of these on hand I use on my Marlin machines and would like to use it as well.

                @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....
