Can't connect to Duet 2 Wifi board, Wifi Module is hot
-
Hey guys,
It was working yesterday, but this morning it is having issues.
I can't connect through the web interface, or YAT.
When I plug it into my windows computer:
There's no blue lights coming from the wifi module.
The Diag red light is on, and stays on
The red light between the reset and USB power is on
the green light for 3.3 is on, and the red for 3v is on.Within a minute, the wifi module gets hot, eventually to the point where it's uncomfortable to even touch.
Any ideas?

Sounds like there have been some overvoltage incident on your 3.3v rail.

Basically remove the SD card, if still hot and still no USB device (Duet or BOSSA) when connecting to your computer then its toast.
Determine cause, evaluate warranty situation would be the next step.

That's too bad.
I removed the SD Card and still get no response. The wifi module continues to heat up.
I connected jumpers to the erase pins and the board would get recognized by my computer but as "Unknown USB Device (Device descriptor request failed)"
Thanks for your advice, I suppose I'll hope it's still under warranty.

Warranty is 6 months; if the fault is covered by the warranty; ref https://www.duet3d.com/warranty
Determining what likely caused it is probably key if less than 6 months old.

@bscott6 please post a good, high resolution picture of your board here. Most likely one of the voltage regulators has failed, and there is usually evidence of this. As @bearer says, warranty is 6 months. When and where did you buy it?
