3.1.0 firmware reboots periodically

[k3lag]

I installed 3.1.0 on my Duet2Wifi a bit ago and since then it has restarted several times. Once in the middle of a print and several times while idle. Here is the M122 output:
console-2.txt

Thanks for your report. Please try the internal build at https://www.dropbox.com/sh/3azy1njy3ayjsbp/AACquxr2m00eV568RZg5QG5wa?dl=0 and let me know whether it fixes the problem. If it does, please run M122 after the printer has been on for some time (and preferably done at least one print) and post the result here again.

[dc42]

PS - @k3lag, please provide your config.g file.

[k3lag]

I just installed the internal build. I'll let you know how it goes in a few hours. Here is my config.g.

config.g

There is a commented out M575 line in there for the PanelDue. I wasn't sure I needed it since I'm using the ribbon cable only.

[dc42]

Thanks.

You actually have two M575 P1 lines in config.g, of which the second is commented out. You need a M575 P1 command to support PanelDue even if you are using the ribbon cable.

I missed the first one when I was checking to make sure I had one. That explains why it worked when I commented it out.

I'm in the middle of a print and so far so good.

Having same issue with my Duet 3. Will install the build linked and report back.

When will the internal build be available for a pi update?

[FBG]

Happen me the same, After update from RC12, in the first print (around 16h) in the middle (around 60%) the firmware reset...

this is the M122:

I go to install the new version of dropbox and i will comment...

Best Regards

[FBG]

Sorry again, inside the link of dropbox i see the file Duet2Conbinedfirmware.bin, and also show 3.1.0 folder, inside this folder also the file Duet2Conbinedfirmware.bin.

Which i must use?

[Thalios]

the file directly in the main folder, not the one in the sub folder. Version should show 3.1.0+ when you do M122

[FBG]

@Thalios thank you, testing...

[dc42]

@luckyflyer said in 3.1.0 firmware reboots periodically:

When will the internal build be available for a pi update?

We'll do an 3.1.1 release within the next few days. Meanwhile you can install the new binary the old way, i.e. upload it through DWC.

[dc42]

Unfortunately I have been unable to reproduce the original problem, or identify what it is in config.g that causes the network task to use more stack than on my test machines.

Therefore, please can any of you who were experiencing this issue install the candidate RRF 3.1.1 binary from https://www.dropbox.com/sh/3azy1njy3ayjsbp/AACquxr2m00eV568RZg5QG5wa?dl=0, check that the issue remains resolved, and report the network task free stack from the M122 report after it has been running for a while. The network task free stack is this bit:

Tasks: NETWORK(ready,136)

I suspect that a good way to reproduce the original fault quickly may be to set the printer doing something that causes motion (e.g. homing) and refresh the browser tab several times while it is doing that.

PS - please check the the build date you are using ends with 18b6.

[Thalios]

Installing. Will report back.

[Thalios]

Problem is back it seems.

M122 result:

I've been printing 2x 30 minutes jobs without hiccups, but it has reset on its own before i printed.

version is 18b6 in machine-specific tab in DWC
