      Hi guys, this is my first post here. I just recently started setting up a 3d printer so I followed the instructions and finished the wiring. I had it connected to the wifi and was monitoring it through the control app. I tried to home x to see if it moved and it said "attempt to move motors when VIN is not in range" while I was trying to figure out what that meant a little puff of smoke came off the board and I powered it off. Now the little processor thing is burnt and it doesn't do anything with power, only the blue power led goes on. Pretty sure its dead, I just want to know what went wrong! Please help! Also, I'm using a 24v power supply with a duex5 and a panel duex.

        Looks done for yeah. That is the 5v chip, so either something shorted to 5v or its just one of those things.

        Add a picture showing the rest of the wiring?

              Also, I had the Panel Duex connected when it happened

                I don't see anything in the pics that could have gotten 5V. Is it possible the Panel was plugged in wrong and was dead shorting +5V to GND?

                  I wouldn't think so? there's only one way to plug in the Panel. I don't think I could have gotten that wrong?

                    Yeah, probably not. I was just thinking of one end or the other being "a pin right or left".

                    Something shorted the 5V line (probably).

                      the only possibility is to plug the 10 pin connector in the wrong 10 pin header on the duet that would short 3.3v to 5v. on the PanelDue its all keyed and polarized, and I don't think putting the 4 pin connector on the Zprobe header by accident would cause a problem.

                      anyways, there has been a batch of bad 5v regulator chips, the duet people are probaly able to determine from the serial number if that could the case and consider warranty replacement or ask for more information if needed.

                      one thing to note is your Vin wiring looks very thin, is it just temporary maybe?

                        "attempt to move motors when VIN is not in range"

                        Do you think that could have been why I got the "attempt to move motors when VIN is not in range" message / error?

                          The thin wires could cause excessive voltage drop and resulting in the error message, but would depend on how thin the wires really are, power supply voltage, heater power and motor currents.

                          Its most likely not related to the failing of the 5v regulator chip.

                            So yeah the power wires were temporary. The power supply came out of a Delta style 3d printer and I just hadn't gotten around to switching them out. Laziness on my part. Off hand I'd say they're 18-20 gauge.

                              Forgot to add; maybe post when and where it was purchased as there isn't much point in waiting for the admins to consider it a warranty replacement if its already out of warranty. Sounds like its a new board though?

                                Yeah, new board maybe 4ish months since I bought it from Matterhackers.

                                  Hi, sorry to see you've had a failure.

                                  Have you measured the voltage at the power supply output with a multimeter just to ensure it's within expected range?

                                  Please contact Matterhackers and initiate a warranty replacement. You can refer to this thread.

                                    There’s a hole in his voltage regulator, I doubt the problem is a lack of Vin.

                                      Thanks for everybody's help. Just received a new board and I'm going to try again.

                                        Be sure to verify that your PSU is outputting 24v and not 36v or something ridiculous.

                                          Output is 23.9v

                                            @Phaedrux I think you're on the right diagnostic path. The only way this goes form operational to a "hole in his voltage regulator" that also triggers the Voltage out of range warning, from my experience anyway, is overvoltage. A poorly designed PSU can have a large poorly regulated inrush when powering it up. I have a few older warn out 24volt supplies that will spike 60 volts on power-up. In my old power supply instance, connected to AOZ1284 Buck controller in the D3 that only has a max operating voltage of 36v will certainly brick it.
