        @Luk14, it sounds as though the SPI communication between the MCU and the drivers has broken down. However, it's possible to get that error if the 24V PSU is overloaded, so that 24V power is applied briefly but disappears again when the MCU starts communicating with the drivers. Is the blue LED that indicates VIN power lit continuously?

          Yes the LED lit continuously. The 24V PSU is a MeanWell RSP-500-24. The 5V on is a MeanWell RS-15-5. When I use the internal switching regulator the error message disappears. Is the 15W PSU too weak to power the board?

              15W (3A @ 5V) is more than enough to power the Duet. However, the fact that it works OK when you use the internal 5V regulator suggests that there is a power issue with the 5V supply. How have you connected that 5V PSU to the Duet?

                I connect the 5V PSU directly to the board. I checked the wiring twice. I also tried to use a USB PSU. Same result...

                I used this guide:

                  @Luk14 do you have anything else on the 5v supply? LEDs etc. Also, are you using the 5v supply for anything else on the board (e.g. 5v fans)? Just wondering if any of them could be causing issues for the power supply?

                    I have just connected the board, no fans, motors, sensors etc.

                          Did you connect the PS_ON pin of the Duet to anything, or leave it not connected?

                              can you confirm the board works as expected when using the internal regulator like you reported above? Please try with your 5V supply disconnected, the 24V supply connected and send M122

                              Thanks

                                just to make sure. when put the jumper on the external 5v supply pins, you removed the jumper from the internal 5v supply pins?

                                  Yes, without the 5V PSU the board works just fine and I am sure that i use the right jumper configuration(s).

                                    When i switch from the 24V to the 5V supply quickly (just change the jumper position while it is running) i don t get any error message.

                                    Edit:

                                    If i turn on the 24V PSU first and after some seconds the 5V PSU everything will work fine.

                                        @Luk14 If its working fine using the internal 5V regulator then we need to work out why the external 5V supply is causing the issue. Please can you measure the voltage level between 5V and Ground on (e.g.) the PanelDue header using a multimeter to confirm that when the external 5V PSU is attached the Duet has 5V on its 5V rail (not just on the power supply input).

                                          PSU: 5,00V
                                          pin1/2: 4,65V

                                          I increased the voltage to (5,44V/5,05V) but the error message still occours.

                                            @luk14, just to be clear: when do you see this error message? Is it:

                                            1. Just once when you apply external 5V power, when VIN power is not already applied;
                                            2. Just once when you apply external 5V power, when VIN power is already applied;
                                            3. More than once; and if so, when?
