    Overtemp shutdown would mean too hot to touch for more than a second.

    Do they still get hot when motors disconnected?

      They do not when the motors are disconnected

        Then I would double check that your motor wiring is correct.

        Are you using a Duex as well? Can you test the drivers there?

        Has anything changed recently on this printer?

          Yes it is using a duex, how would I test the drivers from there?

          The board we had before failed, it was working fine for a few years. The wiring is the same as before, the main visible damage was on the MicroSD card

            So this is a new board? Has it ever worked?
            Do you know what the cause of the previous failure was? Seems like a pretty bad short. Was the cause corrected?

            I fear history may be repeating.

              This board has only been hooked up for a couple of days now.

              We are not entirely sure what the cause of the previous short was. Like I said earlier this printer was running fine for quite a few years. It happened when there was an issue with the "always on" port that was being test. It smelled like something was burning which was found to be the SD card. I'm not sure how testing that caused such a big reaction.

                I think you need to closely inspect the wiring and the board and surrounding area. Something seems to be shorting. Are you able to test the motors in another printer? I fear that whatever caused the previous damage is still present.

                  Yes there are other printers that could test the motors. Do you have any suggestion on how to go about this?

                    connect the motor to the other printer and configure them appropriately and see if they work correctly there or not.

                      That SD card damage looks to me like something is shorting +3.3v to a 5v or 24v rail...

                        I tried the motors on a different working printer which then showed the same errors.

                        I then put working motors on the broken printer, the motors then read the same short error

                        Could it be and issue with the power supply?

                          Please post your config.g and the results of M98 P"config.g"

                          Are the driver chips themselves hot?

                          Do the errors remain if you disconnect all of the motors (when the board power is off)?

                          After some time the errors do occur with the disconnected motors

                            So you tried the motors from your railcore on a different printer and it had the same overtemp/short to ground errors?

                            And new motors on the railcore had the same as well?

                            It sounds like you've had a pretty significant short that has maybe damaged the coils of the motors and damaged the drivers.

                            As I said before, I think you need to closely inspect the wiring and the board and surrounding area. Something seems to be shorting. And I think some damage has already been done.

                            Can you post some close up well lit photos of the duet? There may be some damaged chips.

                                    Have you taken it out of the enclosure and tested it on a bench yet?

                                    If the original cause of the short is still present and has damaged the new board as well I'm not sure what more we can do.

                                      I tried taking it out and there were still some errors or it just not doing anything at all (just says successfully initialized in the console). Since this board is new it should be covered but do you have any idea what else should be replaced or looked at?

                                        With the board on the bench can you go through this guide and see how far you get?
