        No, here is fine.

        Make sure the endstop pin you're using matches the pin name you're using in the command.

          yeah... duex.e2stop is the far right endstop on the duex. it does nothing. ive also tried the other endstops with respective names.

            Can you post your entire config.g?

            Did you specify the pin with M950 J?

              no i did not. it seems to be missing from here.

              i dont quite understand it. i tried J6 but that didnt work. is there a page that shows the pin numbers and names? or do i also need to add C to M950?

                oh i found this, do i just add M950 J1 C"duex.e2stop"?
                how many values are there for J?

                  My understanding is that J is just the index number. The pin being attached to that index is the actual physical pin name being used. "duex.e2heat" for example.

                  From the M950 wiki entry example: M950 J1 C"!^e1stop" ; Input 1 uses e1Stop pin, inverted, pullup enabled

                  Then in the M581 P you'd reference the J number from the M950.

                  M950 J1 C"e1stop"

                  M581 P1 T0 C0

                  J1 = P1

                  At least I think that's how it's working.

                      Not sure, but if i remember correctly what i readed other day, you have to enable pull-up for duex endstops. So your M950 should looks like :
                      M950 J1 C"^duex.e2stop"

                        just tried that. still nothing. i wish all the RRF V3 information was more centrally contained.

                            Yes. Firstly make sure the switch you've connected is actually working as it should. If you go to the web interface you should find a tab that shows the end stops and their trigger states. I think it's "settings - machine specific" or some such. The end stops are listed in numerical order from 0 so it might not be obvious which is which. But no matter. Activate your switch while observing that page. One of those end stops should change state.

                            If the switch shows triggered when it isn't and vice versa, then you'll need to invert things so that it detects a falling edge rather than a rising edge (or vice versa). That is done by using either S0 or S1 in your M581 (can't remember which is which - try them both and see which one works).

                                a new development, apparently

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

                                makes it reset when i home the Y axis...

                                    @Phaedrux just a bare switch wired normally closed. after i commented that bit out, it homed all just fine. also if i just pushed the switch by hand it wouldn't reset, only when i ran home y or home all

                                      also if i just pushed the switch by hand it wouldn't reset, only when i ran home y or home all

                                      Can you post your homing files? I have to admit, I'm having a hard time following along. Do you think you could summarize what exactly you have hooked up and how it's configured?

                                        the X and Y endstops are NC switches wired to the duets endstops outer two pins. the emergency stop switch is a NO red push button, wired to the duexe2stop outer two pins. and the Z is a bltouch.

                                        im in the process of building the printer, so i just recently was able to test the homing. when i did, it homed X just fine, but when i homed Y, i would lose wifi connection. so i commented that estop code out as a random guess and it homed just fine. so i uncommented it again and just pressed the switch by hand in various ways as to trigger a rising or falling signal, but it did not reset. BUT when i ran "home all", it would make it to the homing Y part and reset, or if i just ran home Y.

                                        (i think it has to do with the way and timing of the quick move to endstop and the second pass that made it trigger, idk)
