Duet 2 Ethernet DWC disconnecting since upgrading to 3.5.1

clegg78

My Duet2 has been a workhorse working mostly flawlessly for the last couple years But since going to 3.5.1 today... the DWC continuously drops connection and reconnects when I am printing and sometimes when the printer is idle.

Overall the upgrade is good it seems, but this makes the printer rather unmanageable. I have a PanelDue 7i as well and I see it going into a connecting state as well at times.

My Config: (excuse all the commented out bits, this config has evolved over 3 or 4 years now)

@clegg78 Try to increase the number of AJAX retries in the DWC settings -> Machine-Specific -> Communication to 4 or 5, that should help. We're working on a fix.

clegg78

thanks, just changed that and it seems to work at least functionally. Good to know its a known issue!

clegg78

So this was moved to the Beta Firmware channel... is 3.5.1 beta?? if it was I wouldn't have installed it (been avoiding 3.5.x builds for months to avoid installing a beta version. On the github it looked like a full release.

@clegg78 Yes, 3.5.1 is the full release. The thread has been moved to 'Beta Firmware' to make it easier to track bugs and update threads when 3.5.2 betas are released. We might even ask you to test it...

@droftarts Sounds great, just wanted to be sure I wasn't pulling from the wrong repo or anything
