Solved Duet 3 Mini 5+ VIN under-voltage issues in SBC mode

[lodger]

I have come down this morning to find a stalled print. Here is my M122,

@lodger, was that a print or a simulation?

Please can you try the firmware at https://www.dropbox.com/sh/6203euyyobllic5/AABTHIbn7F_maK9p-oy7vq3Ea?dl=0 with the same file to see if it happens again.

[lodger]

@dc42 Hi,

Yes it was a print. I will just put the kettle on and update and print. It was a 10 hour print so i may not get back to you till tomo.

Edit:: I have updated and run a Similator of the same file. Without problems !
Just running the print now .

[lodger]

@dc42 Mornings.

The print completed . with no under voltage triggers at all. I will try print something else and report if i get any more problems

Thanks for the update.

Anyone else having this problem and happy to use beta firmware, feel free to try the firmware that I linked to above. It's compatible with DWC 3.3beta2.

[Serbitar]

I have put my machine back into SBC mode running the linked beta firmware.

It completed a 12h print over night, print queue has shorter jobs for the next few days. I will update if there are any under voltage detection issues.

[dc42]

@Serbitar, thanks for the update.

Not fixed i'm afraid

Just to add another voice, I and also getting this same issue.

Last night, 70% and 5 hours into a print it just stopped, and displayed VIN undervoltage event (0.0v) and then Insufficient axis homed

My setup is based around a coreXY machine, with a dedicated meanwell 5v 5a psu for the pi, and a meanwell 24v 6amp supply for the printer, the hot bed is 240v

Also, this hasn't happed until recently - i think after i did an apt update. so it was probably fine on 3.1 but not 3.2

[lodger]

@ukwebb Have you tried the beta DC24 posted above.

[dc42]

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

Not fixed i'm afraid

Please can you run M115 to confirm the build date of the firmware you are using.

[Serbitar]

@dc42

FIRMWARE_NAME: RepRapFirmware for Duet 3 Mini 5+ FIRMWARE_VERSION: 3.3beta2+1 ELECTRONICS: Duet 3 Mini5plus WiFi FIRMWARE_DATE: 2021-03-19 18:26:13

[Serbitar]

After the previous failure I dropped the SPI rate to 2MHz but that hasn't helped. Printer just stopped while doing G29 with the dreaded under-voltage event.

[dc42]

@Serbitar, thanks for the additional data point.

[ukwebb]

@lodger No i haven't, as @Serbitar has already said its not fixed the issue

[droftarts]

@Serbitar I've been running 'air' prints on my test rig today. I've had one under-voltage event, 1h 18m into a 3h 30m print, but running the same exact file and settings did not provoke another. So trying to get to the bottom of this issue is, unfortunately, taking some time.

Ian

[Serbitar]

@droftarts Yeah. I haven't worked out a pattern yet. Please let me know if I can do any useful testing.

[lodger]

@droftarts When DC42 ask on Saturday I also printed the same file without issue .

I have been printing around the clock up till Tuesday. Again without issue. There is just no patten.

I have one of the first batch of boards, and on a earlier firmware (dont ask what one).
I am sure i had this happen in standalone mode. So since Tuesday i have been printing non stop trying to prove this.

I have to say though i am getting bloody sick of all these massive 3dbenchy boats lying around my living room. lol

[dc42]

I have put new firmware at 2021-03-26 10:59:15. Those of you who have experienced this issue and have an idle machine, please can you try it and do a print (an air print will do, no need to waste filament). If you get a VIN undervoltage event, please post a M122 report. M115 should report firmware date 2021-03-26 10:59:15 for this build.

[Serbitar]

@dc42 Same dropbox link as the previous one?
