I got it with the d300vs kit from ultibots in july. I'm in the US and it's 1.02.

Hmm, no damage to U2 and all the IC's look fine, as far I can tell. I'm still getting the normal array of LEDs when powered. It happened in between prints, but there wasn't any smoke/smell. I'm at a loss, but it's definitely non-responsive.

Yep, now that you mention it, it's burning up!

Hi! Thanks for the suggestion. I am running on USB power, I tried everything you wrote, but no luck.

I saw that BOSSA is now compatible so I tried using that via my mac. I get about 5% into writing the file before I get a failure.

Hi! So earlier today I had inexplicable connection failure with my Duet Wifi. No wifi connection, no USB connection. I followed the instructions here: https://duet3d.com/wiki/Updating_main_firmware and tried to use the erase button + reflashing with SAM-BA.

Everything goes smoothly until I after I send the .bin. When I hit "Compare sent file with memory" it tells me there's no match. When I 'Boot From Flash (GPNVM1)' I get told it failed. Either way, the duet becomes completely undetectable to either the windows computer or my mac. I have to hit the erase button to get it to register in the COM ports.

I've tried 1.19 and 1.18 Firmwares and SAM-BA 2.16 + 2.17. I've also tried running the program as admin in compatibility mode, something mentioned in another thread here. Any help would be greatly appreciated!
