      Probably compatible with this https://duet3d.dozuki.com/Wiki/Power_Wiring#Section_Controlling_the_external_power_supply

      But since they don't provide any documentation, or release the sources for their more than likely RepRap forked firmware I cannot say for sure. Maybe someone else has already tried?

      However if it is compatible with the Duet documentation, then you need a separate 5V supply as outlined in the wiki.

      Edit: would maybe look at Makerbase MKS PWC V2.0 instead, they're about equally shady but has 5v supply and signaling seems to be compatible.

        Hmmmmm ... So it says: Try it.

        Unfortunately, I do not really know anything about electronics and really only understand the absolute principles.

        I also have the MKS PWC 2.0 here. How would you have to wire that?
        Do I have to wire this as stated in the description for the MKS PWC, or do I have to pay attention to something here? The 5V voltage described in the wiki disappears when using the MKS PWC module?

          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

          https://duet3d.dozuki.com/Wiki/Setting_up_to_resume_a_print_after_a_power_failure

          gomines created this issue in makerbase-mks/MKS-TFT

          closed MKS PWC (Auto-Off) + SBase #112

            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 🙂

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

                  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

                        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 😃 i got a solution. now the baord turns ON with the front button.

                          alt text

                          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. 🙂

                                  @ediik Hi! I came across this thing. 🙂 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?
