      Can you send M122 and post the results?
      Can you send M98 P"config.g" and post the results?

              Good that should be safe - I think.

                      The first one is pretty obvious what it means. The fan 2 is because you have M106 P2 with nothing else so it's just reporting the settings of fan2.

                      I should have also asked if you could send M122 B1 and M122 B2 to check the expansion boards as well.

                      Was that M122 captured after it crashed?

                        m550 I have that on all my machines, never took the time to look into it..

                        I will launch another "test run" tomorrow then take the m122 from all the boards when it crash

                          Use M122 B1 and M122 B2 before your test to make sure the expansions are running 3.2 as well. If not, send M997 B1 and M997 B2 to flash them as well.

                            So I did flash them to the last update (they where at 2020-12-20, they are now at 2021-01-05)
                            and here my m122 and m122 b1/b2

                              @Phaedrux I realized something else: the pi actually do a reboot when the board shut down, it doesn't just loose power.

                                Now that they are all on 3.2 hopefully that will show an improvement.

                                If it does crash again get an M122 afterwards and setup this monitoring on the pi.

                                  I did but they didn't gave me any info, so I did it again and recorded the whole thing.
                                  video here (1.30 min)
                                  the video is not publish publicly, you can only see it from the link. I didn't want people to have the wrong idea.

                                  you can see at 1:20 everything just *freeze as the whole system just quit.
                                  when I reboot I have no error message or anything, it just boot as usual.

                                    And when it boots up again, gather a M122 so we can see what the last reset reason was.

                                        I think we have our issue here: Last software reset at 2021-01-22 13:19, reason: HardFault undefInstr, Platform spinning, available RAM 145856, slot 2.
                                        Slot 2 mean the second 3HC in line right ?
                                        Im having some issue with him, loosing connection (red led start flashing fast). I didnt bother as it does the exact same job as the first 3HC the print was going anyway.

                                          I've flagged this for review. Will just need to wait for time zones before anyone can take a look.

                                            Im having that fault every 10 min now while trying normal print speed..:
                                            HardFault undefInstr, Platform spinning, available RAM 145856, slot 2
                                            since I updated the boards.. Ill just shut it down for now.

                                            no worry I know we are not in the same time zones. thank for the help
