      When you connect 12V power with nothing else connected to the Duet (no USB), do the red 5V, green 3.3V and blue VIN LEDs light up?

        Hello @dc42

        I just tried to just hook up 12V and ground. Like you said the three LEDs light up. I also bought a new SD Card. The Controll finds it but I wasn't able to Boot up yet.

        Best regards

          Hello @dc42

          Best regards

          Please explain what you mean by "The Controll finds it but I wasn't able to Boot up yet.". How do you know that the controller finds it?

          Have you gone through https://duet3d.dozuki.com/Wiki/What_to_do_if_your_Duet_won't_respond ?

          As all 3 LEDs light up, it sounds that U3 is still working. maybe the component that the smoke came from was a fan mosfet - does any of them look damaged?

            Hello,

            so if I connect the Maestro via USB to my computer I find the COM port in YAT. I can also type in the M-commands. M39 is giving me the capacity of the SD-Card and M503 shows me the firmware. With M552 I can set the Ethernet but if I connect the Ethernet cable nothing happens. I can't start up the webserver. That's what I mean with I can't boot it up.

              if you run just M552 after connecting the cable you get the IP address of the board?

              and what error does your browser give you when trying to access the IP? Timeout or HTTP/404 Not found?

              (Edit: if the SD card got corrupted, did you download the Duet web control files and put them in /www on the new SD card?)

                • Do the LEDs on the Ethernet socket flash?
                • Are you able to ping the IP address of the Duet?
                • Is the W5500 network chip on the Maestro getting hot?

                  Hello,

                  sorry I was on vacation, so I couldn't work on it.

                  I replaced the SD Card and structured the folders like on the documentation written.

                  If I run the M552 Code I see following:

                  M552
                  Network is enabled, configured IP address: 0.0.0.0, actual IP address: 0.0.0.0
                  ok

                  But with M552 S0 i cann't disable the network adress. There are no LEDs flashing when I connect an Ethernet Cable. I just looked closer to the W5500 and it looks like that there is a crack in the chip.

                    It sounds to me that you had a short between +3.3V and something else, and that blew the SD card and the W5500 chip. Those two components are the ones most often blow when there is over voltage on +3.3V.

                      A okay but that W5500 seems to be really hard to replace. So I guess I have to purchase a new one.

                      Would you recommend me to buy the Duet 2 Wifi. Because there are acctual fuses on it?

                        It's not that hard, an SMD hot air station or ChipQuik will remove the old one. Which country are you in? There may be a repair facility in your country.

                        However, I suggest you check the wiring carefully first, to avoid the same thing happening again.

                          I'm from Germany.

                          So you think it could be possible to repair the board.

                          I will defintly check everythink before powering up.

                            if you have a local CCC i am sure they will help if you provide the components and a box or two of club mate.
