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

dc42

I've put another firmware build at https://www.dropbox.com/sh/kc7bxqp0s2jjoks/AACf_aOUtEMa8Ix9HXU41hQla?dl=0 to try to pin this down further. Again, if is is convenient, please install it and do an air print to see if the issue still occurs.

Serbitar

Thanks for your continued support! I have installed your latest build.

Conveniently I'm currently printing batches of smaller parts so no major loss if the printer stops mid way through one of them.

Afternoon,

Sorry to say i have had undervolt again. This time network fully locked up. and i had to plug in a keyboard and monitor to get the M122 off . So sorry about the txt file

M122.txt

Web page ,SSH and remote desktop fully stopped.

dc42

@lodger, thanks for that. It's a useful data point, because it eliminates another aspect of the hardware and firmware that is only used when there is an attached SBC.

Tripped over the issue again:

@serbitar thanks, that confirms that the latest change did not help.

PaulHew

I am also experiencing this issue.

My machine was not doing anything, Just completed a heater tune. Below are the last 3 entries in the log.

28/03/2021, 19:03:05 	Warning: VIN under-voltage event (0.0V)
28/03/2021, 16:17:33 	Edit the M307 H0 command in config.g to match this. Omit the V parameter if the heater is not powered from VIN.
28/03/2021, 16:17:33 	Auto tuning heater 0 completed after 4 idle and 7 tuning cycles in 1336 seconds. This heater needs the following M307 command:
 M307 H0 R0.853 C250.9 D5.98 S0.60 V23.9

Pi has a dedicated PSU. Mini 5+ is power by a 300w meanwell.

Do you need any other info?

dc42

@paulhew, are you running with attached SBC, or in standalone mode?

PaulHew

@dc42 With a SBC. Pi4.
Regards, Paul.

droftarts

@paulhew the cause of this issue is still a bit of a mystery; I’ve been running air prints all weekend with different firmware from dc42 to try and narrow it down. It shouldn’t be a problem if you run in standalone mode.

Ian

PaulHew

@droftarts I have been trying to get back to a working printer after the couple of hiccups I have encountered after moving over to a Duet Mini 5+ and 1LC, the BLT being the main one, Appreciated your guidance on that Ian.

If I can help test, please let me know. I would be more than happy to run some air prints, however that is done.

PaulHew

Just had another under voltage.

For info....

droftarts

@paulhew Thanks. Please post response to M115, which shows firmware version and date. We're currently testing newer firmware versions internally, but this problem is proving quite elusive.

@paulhew Thanks. Is that in SBC or Standalone? I think we haven't seen any 0V events confirmed in Standalone mode.

@droftarts Ian, SBC mode.

I'm seeing this too. DuetMini5+ Ethernet in SBC mode (RPi 3B+), M115 for mainboard and toolboard below:

I left my printer sit powered on this week, and see 3 VIN undervolt events while idle. It also died again 3 hours into a 5 hour print last night. I'm happy to do whatever troubleshooting would help folks gather more info to get the root cause nailed down.

dc42

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

I left my printer sit powered on this week, and see 3 VIN undervolt events while idle.

That's the first time we have seen this issue when the printer is idle. Perhaps it just wasn't noticed before. What was the voltage reported with the undervoltage events: 0.0, or a higher value?

Fletcher

@dc42

Also 0.0v. It's possible I mis-read my logs, but I am pretty sure of what I saw. Also of note: for at least some of that time, my heater was on because I am an idiot (but thankfully I didn't burn my house down). Of course I closed the RRF tab in Firefox this morning because my laptop was dragging -- is there any way to retrieve historical console data from SBC, so I could potentially see exactly when those messages happened and if the heater was on at the time?

[edit]On further thought, I'd say it's more likely that I misread my log, than that this is a new problem you haven't seen before. I'm going to leave my machine on and idle again with a console window up and see if I can capture this again.[/edit]

[edit]I can, in fact, Google, so I've enabled logging with M929 S1 P"vin-debug.log" and we'll see what we get. Is there any harm in adding this to my config.g considering I'm running on a 32gb SD card and there's no way I'm anywhere close to filling that? Would be nice if we could do auto log rollover (ie: save to a new filename after the file reaches a certain size) but c'est la vie! [/edit]

Serbitar

@fletcher You can probably get logs from the SBC:

sudo journalctl  --unit duetcontrolserver
