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.

Looks and sounds like the same issue I have.
https://forum.duet3d.com/topic/36643/randomly-reconnect-of-dwc-on-duet2-ethernet?_=1727016238232 isn't it? Started with 3.5.2 and also present with 3.5.3.

@Phaedrux

you are right, I uploaded a new one.

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.
