I have no idea.

The terms of the warranty must be on the E3D web site somewhere.

And they are really pretty good about bending the rules on occasion.

Tried using bossa to flash new firmware and recover but won't connect via usb at all.

you followed https://duet3d.dozuki.com/Wiki/Installing_and_Updating_Firmware#Section_Fallback_procedure_Num_3 ?

if so odds are the cpu is fried indeed.

Is this thread for the W00955 board shown in the other thread then? The one that might have a problem with u2, that would explain it not working with usb.

wdenker

@bearer yes I was told to start seperate threads.

@wdenker I'd guess there's a short through the driver to ground, though not sure why there's enough 3.3V for the LEDs and WiFi to come on. It's possible the main processor has failed, though the SD card and Wifi usually fail first if 3.3V is overloaded. Can you post a picture of the back of the board, too? Have you checked the fuses? The 7.5A possibly looks discoloured.

Did the board ever work, or did this happen at first power on?

I can't see much wrong with the Duex, but again, check the fuse (it doesn't look quite right).

@droftarts all of the fuses are fine unfortunately.

bought from Filastruder in March of last year

So this is a Duet2Wifi and a Duex5 that both don't work?

They were bought in March, but when did they stop working? Did they ever work?

When the Duex is connected to a working Duet2, does it show up in the M122?

wdenker

@Phaedrux they stopped working within an hour of being configured. I don't think the duex 5 ever worked.
