          It was stable for almost 24 hours, which is positive change, at least! Thank you for all the work you're putting in on this issue.

            All, please try the new firmware at https://www.dropbox.com/sh/0mwfe22wepk5efh/AAB6Lp0rwBPjVK2R4SxbKhLya?dl=0. M115 reports it as 3.2beta2+2.

            This version avoids using the ADC DMA sequencer completely, so I am hopeful that it will solve the problem. I was worried that the additional ADC interrupt load would be excessive, but with careful code optimisation I have got it down to 0.5% of total CPU time.

              @dc42 Looks like this version (and probably the other recent ones) breaks duetcontrolserver.

              With 3.3b2 the logs are nice and quiet, with 3.3b2+2 the duetcontrolserver log is a fast rolling spam like this:

                  Actually this is a bit weird. I just went through the remaining versions in sequence and 3.3b2+2 isn't spamming the logs.

                    @serbitar, I've updated the binary at https://www.dropbox.com/sh/0mwfe22wepk5efh/AAB6Lp0rwBPjVK2R4SxbKhLya?dl=0 to avoid DCS reporting those errors. The build time reported by M115 is now 21:29:10. The previous version was 18:55.

                      @dc42 said in Duet 3 Mini 5+ VIN under-voltage issues in SBC mode:

                      With the 18:55 version I had a print paused over night and the printer didn't have any VSSA or VIN troubles.
                      Print has now been resumed and will upgrade again later today after it finishes.

                        Thanks. I am 99% certain that my rewrite of the ADC driver has fixed this issue, so I will mark it as solved. Feel free to revert that if the problem recurs.

                        For others who have experienced this issue, thanks for your patience. The fix is in the Duet3Firmware_Mini5plus.uf2 file at https://www.dropbox.com/sh/0mwfe22wepk5efh/AAB6Lp0rwBPjVK2R4SxbKhLya?dl=0. The 3.3beta3 release will include this fix.
