      ;T3
      M563 P3 D3 H7 F3   ; define tool 3
      G10 P3 R0 S0            ; set initial tool 0 active and standby temperatures to 0C
      M572 D3 S0              ; Set pressure advance on Extruder Drive 0
      
      
      M591 D3 P7 C"duex.e5stop" S0 R25:1000 L12 E20 A0
      

      when running a M591 D3. i am not getting any data collection. even after a very long time.

      I purposefully increased L so it won't pause when i had S=1. I now changed it to S=0 so it doesn't pause during a print when trying to figure this out. I think I have my extruder drives correct. It is the fourth extruder in line. The wiring looks good too. I can see the encoder LED turn off and one and it is in-sync with the LED on "duex.E5stop". I can't figure out why it is not collecting data.

      BElow is what i am getting:
      m591 d3
      Pulse-type filament monitor on pin duex.e5stop, enabled, sensitivity 12.000mm/pulse, allowed movement 0% to 1000%, check every 20.0mm, no data received

        Which firmware version are you using? Do you have a spare endstop input on the Duet that you can use instead of the one on the DueX?

          @dc42 firmware is 3.3.

          i can try to map it over to one on the duet2 instead but i will have to use duex endstop anyways as there are 4 tools.

            so plugging into E1stop gives the below

            M591 D3
            Pulse-type filament monitor on pin e1stop, enabled, sensitivity 3.000mm/pulse, allowed movement 0% to 1000%, check every 20.0mm, no calibration data

              anyone know why filament sensing works on the duet2 but not on the duex5 endstop input?

                @tekstyle The endstop inputs on a Duex do not connect directly to the Duet 2, instead they connect to an IO expander on the Duet and as such are not supported for filament monitors:

                https://duet3d.dozuki.com/Wiki/Duet3dFilamentMonitor_RotatingMagnetVersion#Section_Duet_Num_2

                Note: The Filament monitor must be connected to an endstop on the Duet 2 Wifi, Duet 2 Ethernet or Duet 2 Maestro. It does not work connected to an endstop on a Duex expansion board.

                If you need to connect 4 then use 4 endstops on the Duet 2 mainboard and connect axis endstops to the Duex5.

                    Yes, and with RepRapFirmware 3 you can use other inputs for the XYZ endstop switches.
