      @deltajegga said in endstop trigger and bangbang questions:

      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)

              Can you send M115 and verify that you're actually running 3.1.1?
              Also, can you send M98 Pconfig.g and report any errors?
              Also the content of M122 report please.

                If you are running 3.1.1 your M581 does require an S parameter.

                    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?

                          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.
