I have a relative "dead" Duet 2 WiFi board.
I've had it for a few months and installed it on my BLV Cube (CoreXY) yesterday.
Upgraded to 2.05.1 and used the reprap configurator tool creating the config files, all worked perfect and did so for a couple of hours.
Turned it of late last night.
Today when I turned it on again, I couldn't get any contact with the board.
Neither USB nor the web interface seems to be active.
The LED on the WiFi interface dosn't turn on and it gets very hot fast.
I tried to read the SD card from the board in a PC, it's not readable. The PC won't recognize it at all.
I Backed up the SD card yesterday, so tried righting the software to a new SD card - didn't change anything, the board is still nonresponsive.
There is no visible defects on the board. I checked the 3 fuses all are intact.
So basically I'm out of ideas!
Any suggestions?
