      @xxexx Okay, I found what you're referring to: https://duet3d.dozuki.com/Guide/2.)+Wiring+your+Duet+2+WiFi-Ethernet/9#s28

      I've updated the wording. Effectively signal = sense = STP (used on Duet 2) = IN (used on Duet 3).

        "...on the whole Duet 2 board..."

        would be helpful if you would actually read posts that you comment on...

          @droftarts exactly, i could not reply that link, as i did lack privileges - should be working now.

          Thanks for the correction.

            is ambiguous unfortunately.

              @bearer What exactly is "ambiguous" about that - take a look at the Duet2 board layout and tell me where you can find the word "signal" on the endstop pin denomination?

                @xxexx It's ambiguous because 'Duet 2' could be either 'Duet 2 WiFi / Ethernet' or 'Duet 2 Maestro', which are different products. Or it could have been a mistake and you meant Duet 3! Particularly as you didn't link to the instructions you were using. However, you're right, it doesn't say 'signal' on any of the Duets.

                The documentation did (and still does) say to use the outer two pins.

                ... but in the picture you mark the left and the middle pin?

                The picture just shows where the connectors are, not which pins to connect to. See the wiring diagram for a better description of the pins: https://duet3d.dozuki.com/Wiki/Duet_Wiring_Diagrams

                  The Duet 2 diagram also shows that the colour GREY in the key as I/O (which just happens to be the colour used on the stp pin in the diagram) so anyone with a modicum of common sense "should" be able to work it out, but evidently not.........

                    @CaLviNx I don´t have a manual in order for me "to work things out" - if it says "signal" in the manual, then there has to be a "signal" pin in the layout.

                    Anything else is an error in the manual.

                      You dont need a manual, you do however need an operational brain, and the contradictions in your post show you are somewhat lacking.

                        @CaLviNx grow up - you did not actually contribute anything, but criticize me for not using my brain?

                        I did follow the instructions step by step and i allready found several mistakes - btw acknowledged and corrected by Duet allready - so i helped to improve the manual for me and also for others.

                        So grow up or stay away if you dont want to contribute.

                          "Signal" in this case is the generic term for the input pins whose names may vary with connector and board type/version.

                          Consider the Duet 2 WiFi pin names of GND, +3.3V and E0 STOP.

                          GND and E0 STOP are the two outer pins.

                          Is it not obvious that you would connect your end stop switch to GND and E0 STOP?

                            @fcwilt Actually it make a lot more sense to let a mechanical endstop switch connect e.g. 3,3V to a signal input. Open Switch - no Voltage on signal input - closed switch 3.3V on signal input.

                            But connect ground to a signal input?

                              Is how you bring a floating signal and turn it into a LOW signal.

                                @64bit Absolutely, but is that the obvious way to use an endstop?

                                  That is actually very common for a number of reasons.

                                  To simplify a bit:

                                  You want a disconnected pin to go to a valid logic level, either low or high.

                                  There is a resistor on the board/chip that can pull the input to a logic high state when the input connection is missing or open.

                                  Then you have your external switch that pulls that input to ground, the logic low state.

                                  It simply is "easier" to pull an input to ground.

                                  And in any case the docs said the two outer pins.

                                      Use logic or go home.

                                      And the logic is even without any documentation the board says "stop" on the top Silk screen. On the bottom silkscreen it says STP, 3v3, GND.

                                      And using Logic again, anyone with half a brain "should" know you do not short vcc to ground..

                                      And you said you didn't have a manual, if that's so how would you know that it doesn't say signal in the manual you don't have?

                                      And the logical thing to do would be to look at the wiring diagram (if available) from looking at it, you can work out how things work.

                                      Without a diagram the logical thing to do would be to test the system with a multi meter

                                      Now I'm all for calling out the duet team for the obvious failings in the documentation (most of the duet team will be only to happy to confirm) but in this case the fact is you are bitching because you failed to do the most basic of research and failed to carry out simple diagnostics
