      I am working on using Duet 3 and Duet 3 extension board to my core xy printer (based off railcore II) however i am having a few issues with wiring/configuring

      Issue 1: For my z endstop i have a mechanical endstop (2 pin) plugged into pin 2 and 3 of IO_3 port but it won't stop the z axis when homing.

      Issue 2: How can i set up fans as always on for hot ends?

        @ddunn If you're using a microswitch as a Z endstop I think it should be

        M574 Z1 S1

        Z1 because it's at the low end assuming it probes for Z0
        S1 because it's a microswitch not an actual Z probe(not 100% on this one though)

        If your endstops are wired as NC(which they should be) I don't think you need to invert(^) i03.in

          @ddunn said in Duet 3 Configuration/Wiring issues:

          M574 Z2 S2 ; configure Z-probe endstop for high end on Z

          I don't understand why this keeps showing up.

          From the docs for M574 for firmware v3:

          The S2 option of M574 is intended for use only when axes other than Z are using the Z probe for homing. The only printers known that do this using Duet electronics are the RepRapPro Ormerod, Huxley Duo, and Mendel Tricolour machines. When using the Z probe to home Z, M574 Z has no bearing on the probe setup or usage. A Z probe and a Z endstop can both be configured at the same time. G30 calling the probe setup with M558, and G1 H1 Z moves calling the endstop configured with M574 Z.

          Are you trying to home Z with a G1 H1 command or a G30 command?

          When asking questions regarding homing you should post your homing files - please use the </> tag when you post files.

            I should have mentioned this is about the 30th modification that i made to try to figure it out on my own that is why i had z2 s2. I tried z1 s1 before , i did it again to make sure still but allas it is still not working.

              Well it would help to see your homing files.

                I restored the default homing file and went back to the z1 s1 and it looks like it is working now something in the homing file must have been out of whack thanks!

                Still need to figure out how to get the hotend fans to stay on any ideas?

                  Which of these fans is supposed to be the hotend heatsink fan or fans?

                  For thermostatic fans (the ones with an H# and T#) the S value should be S1 so that the fans turn on full power when the temp is reached.

                    i was trying to get the F0,1,2 as always on and F3,4,5 (there are 3 hot ends) to be turned on based on temperature (if i have them backwards i can move cables easily)as of right now none of them are always on.

                      If you want the fans always on maybe the easiest way is to just connect them directly to the PSU voltage and ground. That would free up your PWM controllable outputs, but if you wanted the option to control them as well the config you have looks correct.

                      What kind of fans are you using? Do they work if they are connected directly to a power source?

                        @phaedrux they are just standard two pin connectors on the fans i would prefer to have them connected to the board via connector vs directly to the psu i know the fans do work as they used to be connected to duet wifi

                          How do you have the fans wired to the port?
                          What voltage are the fans?
