I am in the UK. Ideally I would send it to be repaired directly to Duet3D, but I don't think that is possible as this wouldn't be considered a warranty repair. I also don't see anyone UK based in that forum post.

Maybe if an Admin sees this post they could help?

I have read through that post, would you be willing to have a go at it? Or would you suggest I just replace it?

Ahh, not something I'm equipped to do. Is there somewhere I can send it for the repairs to be done? Or would it be beyond economic repair at this point?

I'd say normal warm up, nothing is too hot to touch.

Unfortunately I cannot get anything to show up in device manager, not even a Bossa port

Hi, thanks for the response. I saw a similar issue on another thread and have removed U2 and tested the board by applying 3.3v via an endstop connector. which causes the wifi module to light up, along with diag (fully bright now but doesn't turn off), the 3.3v. Both the wifi module and microcontroller warm up but I have not got anything showing up on the PC when connected to USB still.

Hi,
While plugging in the ir sensor, I failed to turn off the device and I believe there may have been a short as now I cannot access the board through windows and have gone through https://duet3d.dozuki.com/Wiki/What_to_do_if_your_Duet_won't_respond without any success. I did notice that U2 is heating up when powered. The SD card that was in use at the time is also broken and the diag light comes on dimly red when the device is powered by usb along with 2 other red LEDs.

Is there a way to resurrect the board?

Is there anything else I can do or am I now waiting for an admin to confirm a warrenty return?
Thanks all.

I have tried all you have suggested and nothing has changed. Nothing is getting hot and I cannot find any shorts.
Thanks.

@samlogan87 yes I have, unfortunately none of that worked.

I've been through all of that and I still have nothing showing up
