randomly reconnect of DWC on Duet2 Ethernet
-
after upgrade from 3.4.5 to 3.5.2 I observed a frequently reconnect of DWC when a message is shown on printer display (Paneldue 7i) e.g. leadscrew adjustment after homing or extruder not driven because of cold extrusion.
After upgrade to 3.5.3 I observe the same behavior. It is a Duet2 Ethernet with Duex5.
My second printer with Duet2 Ethernet and Duex2 is still on RRF 3.4.5 without this behavior. -

you are right, I uploaded a new one.

Does this happen immediately after powering on?
Please share your config.g and the results of sending M122 and M98 P"config.g" in the gcode console.

@Phaedrux
No this only happens when a message on printer display is shown (see first post).
I searched the forum and found https://forum.duet3d.com/topic/36277/many-problems-with-3-5-2/18?_=1727095288513
for me it is the same issue. -
@AlexKid Can you please share your config file, too? You might find that increasing the number of AJAX retries in the DWC settings helps.

@AlexKid Thanks for your config file, I could reproduce it here and I believe I found DWC settings that prevent this problem. Can you please try to change the following values on the Settings -> Machine-Specific page and check if DWC remains stable then?
- Communication -> Maximum number of AJAX retries: 3
- Communication -> Time to wait between AJAX retries (in ms): 250
If that fixes it for you, too, I will change the default DWC settings in the next version.
PS: You could also try to increase the PanelDue BAUD rate from 57600 to 115200. That way, data can be sent to PanelDue quicker which could result in better network performance, too.

@chrishamm
unfortunately this does not help.
lots of reconnects with active DWC and performing homing of all axis via Panel Due
also increased Baudrate to 115200
