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

[droftarts]

@paulhew I was just explaining where the problem is, as we understand it now. As such, the screenshots and even M122 reports don't tell us anything extra; they show the result, but not the cause! We've been using M122 P1007 [memory address] to peek at values in memory to work out what's happening, which is not very user-friendly; it crashes the Duet if you get it wrong, then you have to wait for the error to happen again!

The DWC issue you are seeing because you're using DWC 3.2.2 with RRF 3.3beta. You need the new DWC that recognises the new OM values in 3.3beta. At the moment, an updated DWC has not yet been released for SBC mode. There is a DWC 3.3beta for standalone, though.

I'll reply on your other thread about downgrading.

Edit: After about 36 hours of uptime, I got the VSSA fault error too..

I have yet to experience issues on my idling machine. I'll probably try a print tonight and see how it goes.

When I initially installed the upgrade, my extruder thermistor (which is on toolboard TEMP0) was reporting something absurd like 2000C, but turning my 24v PSU off and then on again fixed that. It's been sitting idle with no errors for the last 22 hours.

Setup: 120v wall power, 24V PSU, Raspberry Pi 3B+ with the Canakit PSU, Duet Web Control 3.3.0-b2, 5x motors, live thermistors for bed/hotend. Bed is a 12v bed connected via a MOSFET board, and it's connected to one of the GPIOs rather than the big high-current bed connector. M115 as follows from up-thread:

If any of you wishes to collect data in order to assist me in resolving this, please install the firmware at https://www.dropbox.com/sh/mj25l7gppbui5zl/AABLPxvI8HLr1gCzqLVlKCuea?dl=0 and either do an air print or leave the machine idle. If/when it fails:

• Report the symptoms;
• Run M122 and post the report here.

This firmware includes additional debugging nino in the M122 report.

In the meantime, it would be fantastic if it could pause the print instead of marking it as completed after one of these events, so that it's easier to resume. Or at the very least, it would be useful if it didn't cause the axes to lose their "homed" status.

@fletcher, thanks for that. From the report, I presume the fault was a spurious VIN undervoltage report, not a VSSA error.

Now I have a better idea of what causes the spurious undervoltage reports. I still need a M122 report from this firmware following a VSSA fault report.

@dc42 My machine is happy to oblige!

Omitted: several hundred similar VSSA fault messages before this one. It was still repeating the error when I checked just now, and I had to M999 reset to get the web interface responsive enough to copy-paste!

Hope this helps @dc42

[dc42]

@Fletcher and @paulhew, thanks! Those M122 reports have helped me to pin down the issue some more.

I have put a new firmware build at https://www.dropbox.com/sh/xplbsekbnmmmgtv/AADbXUoNb99JghhlSbzV4Njya?dl=0. When you can, please switch to that one and report any further errors, with M122 reports again.

[droftarts]

FYI you don’t need to be printing to generate these errors; my 5+ and SBC has generated 7 errors in the last 24hrs sitting idle! So save your filament and frustration if you’re helping out with this. Thanks!

@fletcher, thanks for that, it's a different variation that I haven't seen before.

Please can you (any anyone else with a Duet 3 Mini + SBC doing nothing more important) try the new build at https://www.dropbox.com/sh/oxyezimiusnosxa/AAAgjLNKuTL8oEcXgihZqojXa?dl=0.

[PaulHew]

I got one overnight.

It was idle at this time
VSSA errors started @3.17am and finished @5:49am

My printers are in my workshop and I guess the temp dropped to about 8 degrees overnight, even though we had snow!
Not sure if it is relevant.

Paul

[dc42]

@paulhew, thanks. Was it a VSSA warning?

Please try the new build at https://www.dropbox.com/sh/oxyezimiusnosxa/AAAgjLNKuTL8oEcXgihZqojXa?dl=0.

[PaulHew]

@dc42 I edited my original post. Yes, VSSA

Will load the firmware for you now and monitor.

Regards,
Paul.

My M122 after the board started with VSSA faults. Machine was idle at the time.

[dc42]

@serbitar, it looks like you rebooted before doing the M122. Is that correct?

[Serbitar]

@dc42 I had reset the board much earlier, around 17:00.
At 17:24 the VSSA faults started.
At 1729 I did m122 and then reset the board so that I could copy the result out of DWC. The m122 is from before that reset.
