Duet Maestro irratic Network loss
-
Hi,
I'm successfully running a Duet 2 Maestro with firmware 3.01-RC4.
However since a few days I'm experiancing erratic, but steady network losses.
Means every few seconds or also minutes Maestro looses the network connection and reconnects automatically.
All other PCs in the same network do not show the issue beeing connected to the same switch.
I have pinged the system and started logging on the board to get a better idea.
An extraction from the log file of a duration of 10 minutes is added. Event Log Sample.txt
While this duration of time I was loged in via Duet Web Control 2.1.0.Any suggestions and or analysis steps I should undertake?
Thanks

@FoxLab Can you try updating to 3.01-RC7 and DWC 2.1.2? Also post config.g.

Hi,
After the Update to 3.01-RC7 and DWC 2.1.2 situation the irratic network loss turned even worser.
I have now updated to 3.01-RC10 and DWC 2.1.5.
The network loss persists but with a lower frequency.
All other PCs and 3D Printers, in average 20 IPs in use, don't show any connectivity issue.
Any suggestions what to do next?Thanks

The event log suggests that the Ethernet link has been lost, or at least RRF thinks it has been lost. Have you tried another Ethernet cable?

Hi,
I have now tested the board back an fourth starting from standard physical issues like a e.g. loosened contact in the patch cable.
All patch cables used were now previousely tested via a patch cable wire tester.
No defects clould be identified and all cables used are ok.
Going more into depth I identified a thermal problem. After a certain amount of time the networkloss starts. The board is cooled as suggested. When I then take a large fan, used for room ventilation, to cool the Maestro addditionally the network connection loss frequency is reduced again but persists.
All this happens without operating the printer. The printer is just switched on and the board is powered.
My assumptionn is that the board has a defect which is caused by any thermal happening on the board causing a loosened contact. Thus, my asumptionn is that the board is broken.
What do you think?
Thank you

Hi Dominik, thanks for doing the additional testing. My guess is that the network interface chip is faulty. I approve a warranty replacement.

Thank you!

I'm sorry it took so long.

No Problem, it was me who did not take time to test everything in a straigh process.
