SOLVED Duet 2 Wifi rebooting/crashing during print



  • @bwnance thanks.

    The pump has two inputs (kind of) power and control. I know the control line goes to the fan pins but where do you pull off the 24V supply for the pump - is that from the power supply or the duet board somewhere? Are you getting the 24v from the fan header?



  • @markz I'm not using "EZ-Switch" board that was packaged with the berd-air, so both lines are hooked up to the fan header -- as best as i could tell before installing, this was fine, since the fan headers have flybacks wired into them


  • Moderator

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

    https://github.com/Duet3D/RepRapFirmware/releases



  • @Phaedrux just upgraded, will do a few test prints! We shall see...


  • Moderator

    @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.



  • @Phaedrux ah, ty! gonna let this print finish on beta 4, then will update to 4.1



  • @Phaedrux was out of town for the holidays, just started a 4 hour print and the printer rebooted ~40mins in

  • can you post a picture of your wiring on the duet?


  • administrators

    @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 .



  • @dc42 crash on a no-filament run:

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



  • @bwnance
    so?



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


  • administrators

    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.

    Thanks for the update! I'm glad the problem is solved. I'll mark this as solved, but feel free to un-mark it if the problem recurs.



  • @dc42 thank you so much for the support! I really appreciate it 🙂



  • @dc42 and @Phaedrux and @bwnance please correct me if i am wrong i am going to be adding my ez out switch now to as i was under the impression the 1 amp plus 50 percent for start was still ok for the mosfet on fan0 but anyway i plan on swithing to a brushless pump anyway as i found a kvp8 pump that flows a large amount and can run series or parallel.
    I run berd air as well and two things the pump is very noisy it actually can make my camera get artifacts from the emi. Also if you remove the flux ring you will increase rpm as we are not running a high pressure system. Last why are you using a heater block oyu should be connecting 24v constant to the ez pwm board then use the fan output. The only time you would do what you listed would maybe be with a brushless motor that has built in controller and you wanted to run 3wire or try and run a 4 wire with tach but in that situation i would think you would use and endstop output to pwm control the brushless pump so that it only gets 5v unless you want to run all fans at 5v. I say that cause most things do not like the 24v pwm control signal.
