      Do you mean that the current breaks down the MUC when the drive is burned?

      It's possible that a burned driver may feed current into the MCU pin driving Step, Dir, or one of the SPI signals. The input protection diodes shunt this current to Vcc (3.3V). If the current is small enough, operation of the chip will be unaffected. With somewhat higher current, the chip may malfunction, but no permanent damage will be done. Higher still and permanent damage will be done.

      What I would ideally like to know is whether the firmware crashed because it didn't get the expected response from the driver (which I would regard as a firmware bug to be fixed), or the MCU crashed because of injection current.

        I decided to do it myself. Now it doesn't seem like a good idea

        did the parts work out to be more in the end?

          @dc42 After hearing your explanation, I think it's ,the MCU crashed because of injection current

              So if the reset was unexplained, it was caused by a loss of power.

                    He’s done the same with a duet WiFi variant. He’s shared images and videos on our Facebook support group for the blv cube and has stated he’s selling them, but supposedly doesn’t/can’t sell them outside of China (the veracity of that is up to the reader to decide).

                          Well it is open hardware. Though using the logo is not allowed and if being made for sale must be made clear that it is not an official product.

                            Not only does he want help from the Duet team, but he's getting it. Seems like a very strange business model to me.......

                              @Phaedrux no offense. The purpose of making this PCB is not to sell it. I think I should close the theme
