      Hi,
      I had all CAN termination jumpers connected.
      I removed them on the middle one.
      But sadly the problem remains.

        What firmware versions are you running?

        Is it always the same board that gets out of sync? If so, when you swapped the expansion boards over, did the fault move with the board, or not?

          I am running the version: RepRapFirmware for Duet 3 MB6HC v0.6 or 1.0 version 3.0beta12 running on Duet 3 MB6HC
          Yes, it is allways the same board and the fault moves with the board.

            @vali3d I would suggest you look at moving to 3.1.1 for the main board and 3.1.0 for the expansion boards first.

            Owns various duet boards and is the main wiki maintainer for the Teamgloomy LPC/STM32 port of RRF. Assume I'm running whatever the latest beta/stable build is

              Ok, I have updated it now. This was quite some troubble, I had to completly redo the sd card. I will see if that helped in the next few days/weeks.
              Thanks

                Thanks. If that doesn't fix it, I will provide beta firmware for you to try. It turned out that the released firmware runs one of the PLLs in the chip out-of-specification, which could explain a difference between two boards even if neither is faulty.

                  Slightly off topic, but I really like the electronics cabinet you have (and that power supply looks nice too). Do you recall where/what model you purchased for the cabinet?

                      Hi,
                      the expansion lost connection multiple times over the past weeks. According to my obsevations, this happens only under a load on the extruder motors (which are connected to the expansion).

                        Can you send M122 Bx where X is the board number?

                          @Phaedrux When the connection was lost or in normal operation?

                            Hi,

                            I have checked the M122 B1/2 comand. The firmeware update I installed in September, didn´t install the firmeware to the expansions, only to the mainboard. Now I manualy installed the 3.2beta to expansions (with the M997 B1/2) an the mainboard. I keep you updated.
