@Phaedrux I purchased it from capstone_cadem on eBay.
The seller informed me that he would need an RA number to proceed.

@phaedrux I purchased it brand new from a reseller.
I just contacted him, and he said to continue discussing the problem on the forum, just to make sure that the issue is in fact hardware.
It's been in my machine for about two months now. I purchased it in September, and installed it early October.

(Also, I'm not sure about forum edict, do I put the @phaedrux in front of my post every time, or just respond with a normal reply?)

@phaedrux Sorry about the carpet, just got the board out of the machine
The fuses seem fine, and nothing is showing up in Bossa
After checking a few components, I can see a little crater in the u3 chip.
This is strange because I was drawing very little power from the 5v, just a bltouch, a couple endstops, and a panel due.

@phaedrux At the beginning, I went through all the setup procedures, and I was able to get the board to initially work . I setup up wifi, and was able to connect to the terminal with YAT, but it stopped responding a couple days ago.
I used the usb cable that I know carries data, and tried a few other cables for good measure, non of which worked.
I was able to initially connect to the board, so my usb drivers should be fine, and my cable should be carrying data. Just to make sure, I just tried reinstall the drivers, but to no avail.
I also restarted my laptop, and tried my desktop, incase it was system problem.

Shorting the erase jumper doesn't seem to change the serial connectivity, I'm still not able to see anything pop up in device manager.
The LEDs are super dim now. I've attached more photos incase it might be helpful.

Hello all,
I'm not able to connect to my duet 2 wifi via usb or wifi. Initally everything was working fine, and I was able to connect to the board, setup wifi, and update the firmware. Now the board does not show up in device manager.

The board is recieving power when connected to USB, and all the lights turn on, so I'm not sure what the problem may be.

I've tried everything in this guide, to no avail
I appreciate any help
