      Should be able to use the diagram here
      https://github.com/makerbase-mks/MKS-TFT/issues/112

      S1 on PWC to PS_ON on duet. (and 5v/gnd of course)

      And for the resume wire S0 to a free input on the Duet and follow

        Although don't know if the 5V/0.6A provided by the MKS PWC unit is sufficient for the Duet.

        This may shed some light on that:

          First: You mean the Wiring from the first posting?
          This: https://user-images.githubusercontent.com/35586270/36057698-87f482dc-0df0-11e8-983e-dbaf89b09f5a.png

          Second:
          What mean: (and 5V/gnd ofc)?

          I don't understand the "ofc"

          And Last:
          I can use this wiring for the rest:

            Yeah, it has the S1 and S0 labels on the MKS PWC, they are the PS_ON output and PowerLoss input signals respectively.

              Ok ... I read and hope I understand πŸ™‚

              For the rest of wiring I can use this picture too:

              I know the picture is for the MKS Gen 1.4, but I mean the routing for the other cables

                Hi,

                if your goal is:

                • 24v supply on / off via gcode or dwc
                • emergency stop switch
                • reset

                try this:

                0_1556863779814_PulleyxCube_Schaltplan.jpg

                You only need : example for a opto low-level trigger-relay

                  @crazycreator Duet is able to resume after a power loss, if you set it up: https://duet3d.dozuki.com/Wiki/Setting_up_to_resume_a_print_after_a_power_failure

                    My only concern is to have a 16mm button on the front of the printer, with this I want to turn on the printer.

                    If I can turn off the printer with this button, that would be nice, but it is not necessary. I can do that also via web interface

                      If anybody came accross the same thing πŸ˜ƒ i got a solution. now the baord turns ON with the front button.

                      Sidenote: it does not matter where you get the 5v from. The pins from the main extension ports are allready if use on my board (bltouch).

                          @CrazyCreator it does not matter. The lerdge board simply gets 5v from the duet and stays on for the time it has 5v connected. No cdg changes necessary. πŸ™‚

                              @ediik Hi! I came across this thing. πŸ™‚ One question - why don't you use PS_ON signal for controlling Lerdge power module?

                                  Don’t feel bad this module has beaten me as well for time being. I went to the solid state relay setup as highlighted above and was much simpler to get going with the same button. But... I really would like to figure this out too at some point lol.

                                    Little correction, for me, it’s the Makerbase MKS PWC V2.0 module. No matter what I tried, just couldn’t get it to work.

                                      Hello, did anybody the Lerdge Power Modul to work with the Duet. I want to try the same thing. Have a Lerdge Power Modul laying around here. What does the PS_ON pin on the Duet exactly? Act it like a 5v on and off switch?

                                          Here is no answer to this question. I want to turn the PSU off with this modul. When it get 5v continuously from the Duet it stays always on. When there is 5v, GND an PS_ON on that connector how does it exactly work. I know this is 5v in. Does the PS_ON switch the 5V to PS_ON?

                                            Ok the PS_ON pin will be connected to Ground when the PSU have to be enabled. Is there a way to get a 5v Signal to shut the Relay down? See the picture attached.dr6X10S.png
