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

Another occurrence over night.
Is there anything I can do to contribute to investigation?

@Serbitar Thanks for the report.
In SBC mode you could try enabling more detailed logging.

@carcamerarig, thanks for the additional data point.
My best guess at this point is that the DMA for the SPI transfers between the Pi and the Duet is somehow interfering with the DMA used by the ADC. Do any of you experiencing this problem see short-lived temperature jumps too?

@dc42 by the time i'm back at the printer, usually several hours have past since it stopped so the temperature charts have gone past.
I have a few prints to complete in standalone mode and then i will enable the extra monitoring. Is there any way to save logs of the temp values too?

Until I have pinned down the exact cause, it might be worth trying a lower SPI frequency. The frequency is set in the DCS configuration file on the Pi.

PS - if anyone who has experienced this has their machine idle, please can you run some simulated prints, to see whether they can trigger this issue. The increased SPI traffic rate from the Pi during a simulation might make it happen more often. OTOH it could turn out that step interrupts also need to happen for this issue to occur.

@dc42 Happy to try, how would this manifest during a simulation, just console messages showing low voltage detected? In which case I will make sure I have 24Vin active during simulation.

I expect the indications of the problem to be:
- A console report of an under-voltage event, with the reported VIN being 0.0
- If you run M122 afterwards then it will report that one or more under-voltage events occurred and the minimum recorded VIN will be 0.0. Note, a subsequent M122 will only report under-voltage events and the minimum VIN that happened since the previous M122.
You will need to have VIN power applied throughout.

I’ve been spending quite a few hours daily of stop start printing while I’m still tuning and configuring (mostly learning) and have only seen the one which was at a home all, the effect was a crash into the left x carriage carrier, I’m unsure if the error was before during or after the crash.
I’ll be doing more of the same later if you want me to test or log anything, I’ll need some instructions though if I’m to alter some code. -
@dc42 Is 4MHz low enough?
-
Is it worth running some heaters duing a simulation. To give the PSU some load.
During a print my VIN can jump up and down a few points of a volt. But during a sim . She is bang on 24.2v and dont move. -
6ish hours of simulation so far with no issues
-
@WILD9 I ran simulations for 8 hours last night, with no issues. Still trying to track this issue down.

@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.

@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 . -
@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.
-
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.
