      Can you try 3.2 Beta 4? It's believed that a fix for this crash may already be present there.

          @bwnance Just realized there is an odd ordering problem on that page that doesn't list the most recent at the top.

          https://github.com/Duet3D/RepRapFirmware/releases/tag/3.2beta4.1

          Beta 4.1 can be found here.

                    @bwnance, your M122 software reset data doesn't make any sense, so I think it must have been caused by a transient or possible power brownout. Can you run a few more prints to see if any future crashes are similar? You can do air prints to avoid wasting filament.

                    The assertion failure you had with 3.2beta4 is different, that's a known bug that was fixed in 3.2beta4.1.

                      @dc42 Will do dry-runs throughout today. It's weird, sometimes it completes a print just fine, sometimes it fails -- but all with the same file.

                        motors very close to the board .
                        maybe try to add some shielding , or relocate the board just for a test .

                              @hackinistrator Moved the board over and repositioned the berdair to be nowhere near the board... we shall see.

                                  @hackinistrator haven't had a bunch of time, but i've run 3 dry runs so far with no issue - a pretty good sign.

                                    Is the Berdair driven directly from a Duet heater output? If so then I suggest twisted pair wires between the two. Hand twisted will do.

                                    Have you connected a fast recovery flyback diode in parallel with the Berdair? The best place for it is on the motor terminals. Make sure you connect it the right way round!

                                      @dc42 the Berdair is connected directly to FAN0 -- i was under the impression that a flyback diode had been included on all the fan headers in recent board revisions - i might have misunderstood?

                                        @dc42 just got another crash -- should i have the berdair wired differently than i do now?

                                          @bwnance said in Duet 2 Wifi rebooting/crashing during print:

                                          @dc42 the Berdair is connected directly to FAN0 -- i was under the impression that a flyback diode had been included on all the fan headers in recent board revisions - i might have misunderstood?

                                          We don't advise connecting a Berdair directly to a fan port. The starting current of the motor will exceed the peak rated current of the fan mosfet, causing it to fail after a while.

                                            @dc42 I connected the EZ-Switch that the berdair comes with to an unused heater block + a fan header -- This appears to have solved the crashing issues.

                                            Using any high PWM frequency after this ended up resulting in "all or nothing" fan control -- i dropped the frequency down to 20hz and that seems to have solved the issue, though.
