DWC Dropouts on Long Prints

[CNCModeller]

Hi All,
I'm running the latest beta firmware. 3.4 beta 3 on a duet 3 Mini+ with the associated files and I'm regularly getting DWC connection failures during long prints, it seems to happen after at least 12h of printing. I've not noticed any other patterns. I'm connected via a WIFI network that is generally robust. It is something I also saw many months ago but I've not been doing long prints recently, until now.

Fortunately I also have an LCD display so I can track performance, and reset any pauses due to filament detection etc.

Is anyone else seeing this?

Cheers
Barry M

Yes i do get disconnects (like in the morning after night prints). See my opened posts on the topic...

That said it is a lost battle to get any attention on that topic in here...
Earlier the HW was replaced under warranty (got 2 replacements..) lately it aint the case anymore... and you are left living with the erratic behavior

The best you get back is that your wifi network is unstable or your wifi router has flue... while i'm convinced the bug is in the FW..

OK @oc_geek that makes me feel a little better... perhaps it might be worth resetting the WIFI every layer change or something? That should fix any issues that are WIFI connection related.

I seem to remember I had a similar issue on my duet 2 Ethernet TBH.

So I've added the following to my slicers layer change script:

M552 S0
M552 S1

That should solve any external network issues, now lets see!
