Duet Connection Issues
-
Hey there!
Ive been using multiple printer with Duet Wifi and had occasional connection issues. So I switched to the lan version for the latest Printer in hope it would improve stability but it actually got worse. The problem are frequent short disconnections (.5-2 times per minute) which make it super hard to use the printer at all.
I tried multiple Web Control Versions: 2.0.7, 2.0.4, 2.1.7 and 3.1 without any noticable improvement.
Both Duet Wifi and Duet 2 Lan are hooked to a router with fixed IPDoes anyone share this problem or has an idea how it could be fixed?

I would first suggest upgrading to 3.2
https://github.com/Duet3D/RepRapFirmware/releases/download/3.2/Duet2and3Firmware-3.2.zip -
Just tried it without success, everything is now on 3.2 but the issue remains
//edit: had to upload it multiple times because of the connection loss
-
So you had connection issues on wifi and now also on wired. I would suggest the issue is with the router/switch hardware.
-
Do the disconnections occur when the printer is idle, or only when it is moving?
-
Im not too shure that it´s my network as I got multiple duets running and only one is particular problematic. But ofc it still could be an issue. However, I need some hardware to rule out this potential problem.
@dc42 It seems like it doesn´t matter if it´s idle or not

config.g?
Did you confirm the update to 3.2 was successful with M115?
Did it also update the DWC version?
Can you show the dwv console output again with the updated versions?
