      there is more documentation for those in need; https://duet3d.dozuki.com/Wiki/Choosing_and_connecting_stepper_motors#Section_Using_the_internal_drivers with less room for ambiguity.

      (it also shows maestro and duet3 having been changed already)

        @gnydick, we agree with you. That's why all our more recent boards, including all production Duet 3 series boards, label the outputs A+ A- B+ B-.

          Very good. We were knocking on an open door. 😉

            At the very least, you could put a comment on the wiring diagram that tells you 1 & 2 are the different coils and to NOT map A & B to the motor diagram's A & B.

            For Duet 2 this suggestion looks reasonable.

                @T3P3Tony thank you for the effort, but that's more confusing. The whole point was that all the motor diagrams seem to indicate A loop and B loop. This new diagram only makes sense if you understood it to begin with. Keep in mind, I'm viewing this from the "n00b" point of view. I'm suggesting making it fool proof, as there are lots of little pitfalls that can result in $200 mistakes.

                    Don't want to seem boring, but according to
                    "On Duet 2 WiFi/Ethernet these are labelled '2B 2A 1A 1B' on the back of the board, and on the wiring diagram. The '1' and '2' refer to the coil or phase, the 'A' and 'B' refer to the positive and negative."
                    "+" and "-" are currently reversed.

                      @Swift-Tester thats why i left the original labelling on the diagram as well as the AB+- which is to help those like @gnydick who are referring to a diagram labelled with AB+-

                      The +/- are consistent with other Duet diagrams that use this scheme (i.e. black is A+ etc)

                        basically as long as you realise that the two pairs are on pins 1,2 and 3,4 respectively its all good, you can use M569 to set the motor direction as required.

                          I do not have the source, but IMHO this sketch is consistent with Wiki and have the information about special notation D2W uses. The rest is up to the reader.
