        @dc42 Thank you so much for responding quickly!

        Here is a video showing everything going on.

        It has the right green lights. 23.9 v to the board. And the short happened After a wire came loose.

        I saw it burn and give off a small amount of smoke to% my drivers. But signal chain wise the short must have come after the board? Is that true? I waz plugged from the duet the e0 to 4th axis module.
        Thank you again

              @Phaedrux 4th axis cnc that I will send gcode to from the gorgeous duet browser gui.

              Duet browser connects great, but when yoy try and jog the machine manually . whar used to work the night before perfectly... Stopped working the next day?

              Can you see Or catch anything wrong with this video?

              If there are diodes in the board after the stepper driver on the maestro 2, wouldn't they limit any current coming back up to the board?

                @elmoret Thank you. I bought it online years ago. Not sure I can remember. Why do ask?

                  Pull the board from the nest, disconnect any wiring, pull the SD card, and connect it to USB on your PC and see if anything shows up in device manager.

                  What LEDs light up when connected to USB?

                  Does anything get hot when connected to USB?

                  If it does show up in device manager, what does it show up as?

                  If it does show up as a Duet, can you connect to it via YAT terminal software?

                    Is it possible that the anti-static bag is conductive? Do what Phaedrux recommended and pull it out of the printer and place it on a non-conductive surface.

                      (Everything that is ESD had to be conductive to some degree in order for it to dissipate the static charge to ground (when connected to ground))

                        Yep, so my thought was that if the board was placed on an ESD bag while it was powered, the slight conductivity could have shorted some near-by pins on the back of the board.
