Hi @dc42
The WiFi module gets extremely hot, fast - but as far as I can tell no other components are getting hot.
Eras did not change anything - no ports appear on the PC after eras - did it 5 times.
Forgot one thing in the list of connected items:-)
I have a PanelDue 7i connected as well.
it turns on when the board gets power - but no communication with the board as far as I can see.
I got this on in February
Purchased from Filament23d in DK
Reset dos not help.
Wired up was
x, y and dual z motors
X ans y end stops - I plan to use a Bltouch as z probe, but I haven’t finished the testing of the conversion to 3,3V - so that’s no connected yet.
Tool - Hermera. Incl. fans
Headed bed creality CR-10 pro. Powers through a secondary power sup - mosfeet.
And the thermistors for both.
24V power sup.
Solid stat relays for M80 M81
Every thing worked perfectly...... for a short time
@tom18 said in Duet 2 Wifi non responsiv.:
erd
Yes now I have. 
Here is a few pictures of the board.
As you can see all LEDs light up. The DIAG LED stays on - as the WiFi gets very hot i only had it connected for a couple of minutes.
The reset button is free and seems to be working as it is supposed to.
Connecting to the PC - No devices is shown - using the same USB port on the computer as i was when I configered the WiFi yeasterday.
I have not done the erase part. Should I try that?
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?
