      Hi,

      a while ago something strange happened ... let me explain

      I wanted to print a part, and I have followed the usual steps:

      • I have turned on the printer
      • I have heated the bed, not the extruder
      • I have made a Home
      • Given to calibrate.

      But when it had a few points, 4 or 5, I am not sure, Duet has restarted and the Due panel has not turned on, I have no longer been able to connect via Wi-Fi as usual, or looking for it on the local network, in case it had changed ip .

      What can I try?

      This morning it was working correctly, ... What could have happened?

            new info...

            i have try to send a G28, with Putty, and obtained this response:

            G28
            Error: Attempt to move motors when VIN is not in range<LF>
            

            Can be that PSU has down?

              @peirof if you look at the M122 output, its showing that theres no input voltage

              Supply voltage: min 0.0, current 0.0, max 0.0

                  @peirof do you have a multimeter to check the power from the PSU?
                  Also check all the fuses if you haven't already

                                  @peirof I have not had time to prove anything ...tomorrow, but I have a question.

                                  From that fuse. Does the Due Panel also depend? because it is in black

                                    @peirof yes the 5V from the PanelDue is also supplied via that fuse

                                      Hi,

                                      This is a thought out loud, so you can tell me the mistakes I make, since I have no experience in electronics / electricity.

                                      My goal is to identify which component is shorted, and which is causing the fuse to blow.

                                      The components that this fuse monitors are:

                                      • Due panel
                                      • Extruder Heater
                                      • Extruder Stepper
                                      • Axis Stepper.

                                      If the fuse burns, as soon as the printer is turned on, I have to discard the components that have not received power yet ... Which leaves us alone:

                                      • Due panel.

                                      No? Something escapes me? Do you watch any more components?

                                      A component that could cause problems is the Heater ... but if it has not received power when the fuse blows ... I do not think it is the cause of the problem

                                        another question that arises ...

                                        I think I remember, that there have been moments, I don't remember if now, in config.g, in M906 I have or have had a current for 1200 motors, which exceeds the protection of the fuse.

                                        Why hasn't it been burned before?

                                          @peirof Do you have a multi-meter? if your blowing a fuse the safest thing to do would be to check all your wiring for shorts before you connect anything.

                                          looking at the picture you posted above there appears to be stray strands of wire on the right most stepper connector (red wire)

                                            @peirof said in Houston we have a problem...:

                                            A component that could cause problems is the Heater ... but if it has not received power when the fuse blows ... I do not think it is the cause of the problem

                                            Heaters are switched on the ground side not the supply side so a heater that had a short to ground would start taking power as soon as the board has power. That said its unlikely that a normal heater in normal operation will draw 7.5A+ and blow the fuse, however a faulty heater with an internal short could do.

                                            As has already been said shorts in the wiring can also be the cause, most likely is VIN to ground.

                                            It is not impossible for it to be the paneldue, but that is the most unlikely as it gets 5V so it is unlikely for it to draw enough current at 5V to blow the fuse, unless the 5V regulator has also failed short (and then you have a lot of problems as VIN on the 5V line will damage other things as well.
