      i tried

      M950 J1 C"!^duex.e2stop"
      M581 P1 T0 C0 S1

      still a no go. heres a picture, the red switch on top goes from white/green to two white wires down to the duex endstop. it has 3 wires for NC or NO, but i assume that doesn't really matter with the inversion capability. if feel like im missing something obvious.

        It's hard to tell from the photo of the wiring bundle but have you followed the Duex wiring guide on connecting the grounds with a short piece of wire as shown here? https://duet3d.dozuki.com/Wiki/Duex2_and_Duex5_Features#Section_Wiring

        Can you send echo sensors.gpIn[1].value and report the results?

            ;M950 J1 C"!^duex.e2stop"
            ;M581 P1 T0 C0

            You've uncommented these lines right?

            means gpIn[1] doesn't exist, so either the M950 J1 command wasn't run or it didn't work

            What do you get if you send just M950 J1 in the console?

              hahaha, silly me. i guess it would help if i uncommented them.
              ok i get a value of 0 back.

              and if i send the m950 j1 i get back

                And with this? Does it work as expected?

                    I wonder if having the wiring bundled like that is causing the e stop switch pick up the signal from the endstop.

                    Usually when I'm making my looms I always twist the wires to try and prevent cross talk. Can you physically separate the wiring for the e stop from the bundle and test again?

                      ok, interesting. so that solved the triggering when it shouldent problem. (i allways thought that only pwm and data lines cared about twisting.)

                      but it still wont trigger when i press the button. just a reminder im using a normally open switch.

                        Try changing it to normally closed. This should be configurable with the S0 S1 switch, but it's worth a shot.

                        I twist or braid everything when using cramped conduits. Just as a matter of habit.

                            And you're sure the switch really works?
                            Do you have a regular endstop microswitch you can connect in its place to test?

                              yeah i tested it with a multimeter at the plug on the duex.

                                @deltajegga In RRF 3.1.1, the 'C' parameter has changed to 'R'. See https://duet3d.dozuki.com/Wiki/Gcode#Section_M581_RepRapFirmware_3_01RC2_and_later

                                Try changing command to M581 P1 T0 R0 S1
