Duet3 Mini Stalling mid print

[WILD9]

OK,luckily this failed again sooner rather than later, printer is currently in the failed state M122 below. I got the voltage warning again despite bypassing the relay for 24v.

SBC uptime shows no reboot there and no low voltage events in the syslog so doesn't look like the 5v psu (powers the sbc and duet) has been interrupted at all.

for reference the above event occurred at ~11:10 am 06/03/21

does this look like 24V PSU failure?

The under-voltage event and the timeouts writing to the drivers suggest that VIN power was lost briefly.

[WILD9]

This post is deleted!

[WILD9]

@dc42 Thanks, in this case is VIN the 24V PSU as opposed to the separate 5V feeding the Duet/SBC?

[WILD9]

OK, Ordered a new PSU. Fingers crossed.

[WILD9]

No Luck, replacement Meanwell PSU installed and still coming back to occasionally find the printer stopped mid print.

That M122 report is interesting because it says the current voltage is 1.3V. If it says that, you can test the actual voltage with a multimeter as see if that’s true.

Ian

[Serbitar]

is your m122 being done automatically? (i.e. when powerloss is detected?)

[dc42]

May be related to this https://forum.duet3d.com/topic/22031/duet-3-mini-5-vin-under-voltage-issues-in-sbc-mode/7. In summary, we have a few instances of what appear to be spurious under-voltage detection, always with the voltage being recorded as 0.0, and so far always when in SBC mode not standalone mode.

[WILD9]

@droftarts The duet controls my 24Vin it seems to have turned the relay off here hence the 1.3v reading but during printing I'm at 24v The same failures occur with the relay bypassed and Im now on my second 24V PSU.

@Serbitar No, that last one was manually run ~5 minutes after the print stopped but before I had taken any action to restart things.

@dc42 Thanks I will keep an eye on this, is there anything I can do to help with logging etc as I seem to have this occurring quite frequently at the moment.

[WILD9]

Another failure so another m122 with the console messages precursing it:

Unlike @serbitar I notice I have no

xxxx Print auto-paused due to low voltage

line in my logs which I can see in which I can see in Serbitars logs

I'm now trying to look into a simple way to log the Vout of the PSU directly during prints

Thanks, I think this is the same as https://forum.duet3d.com/topic/22031/duet-3-mini-5-vin-under-voltage-issues-in-sbc-mode/7 which has been reported by several users, so nothing to do with your PSU. The fact that the VIN reading is always 0.0 when it occurs confirms that. What I really need is a way of triggering this issue reliably so that I can test possible fixes. Please look at my most recent post in that thread.

@dc42 Thanks, I will move over to that thread for discussion
