I was on firmware 2.0.5 and started having a loss of connectivity through network and Paneldue would lose connection also. This wasn't that big of an issue except this weekend I needed to do a couple of multicolor prints with filament changes and on the first one it was locked up when hitting the pause.
So, I figured I needed to finally go to v3 then v3.2 The update to v3.0 was fine, M115 reported the correct firmware so I uploaded v3.2 and lost all connectivity. No wiring changes were made during any of this, it was installed normally and I had just finished that failed print 30 minutes prior.
I've tried a full erase/reset, commented out M552 in config.g, but am stuck with the 5v, 3.3v, DIAG, and USB leds lit and no connection via wifi or USB. I've tried multiple USB cables and ports but am fairly certain it's just dead.
I bought it in Feb 2017 which is almost 4 years of excellent printing running fairly low current steppers and not printing that often, maybe a few hours/week average except for doing faceshields last year for hospitals and a few other times.
Any other suggestions to try to recover it?
Also, was it just at its EOL? I expected it to last a lot longer than 4 years.
What's next, a Maestro or go to a SKR Mini E3 maybe? I'm not sure I want/need to shell out the money for another Duet. I do have a Paneldue, but it's the second of those as my first died after about a year.
