Duet 2 Wifi rebooting/crashing during print

bwnance

@markz
Resistance on my heated bed (measured at connector on board) is 3.3ohms, it's a 24v bed, so that would be a ~175watt bed, correct? I'm using a Mean Well 24v 350w PSU and my hotend is 50w, so i should have plenty of extra room, wattage wise, right?

24v to the pump is over a fan header on the board (AFAIK newer duets have the flyback diode on all fan inputs internally), I'm not sure how to diagnose if i have noise on the 24v line.

markz

@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?

bwnance

@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

Phaedrux

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

bwnance

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

Phaedrux

@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

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

bwnance

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

I see that 4.2 was just released so i'll update to that and try again.

@Phaedrux no dice, another crash. @dc42 any ideas?

Veti

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

dc42

@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.

bwnance

@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.

@Veti

hackinistrator

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

bwnance

@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.

hackinistrator

@bwnance
so?

bwnance

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

dc42

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!

bwnance

@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?
