@dc42 I havent yet, got a replacement board and successfully got that powered on. Doing that replacement is going on the backburner for a bit while I finish this printer. I've gone ahead and marked this topic and closed.

RE: Possibly fried duet with an in spec power supply
Thanks again. I have the new board updated, that went fine. Wired up power supply and tested voltage. Using a 360w power supply this time. Tested it. Wired for board but havent turned it on because.... I'm not nervous your nervous.
Anyone see any issues?

RE: Possibly fried duet with an in spec power supply
Thanks guys, this is a lot for me to process. I'm going to try giving the wifi replacement a shot, and if that doesnt work might play around with CPU replacement, if only to see if I can. This is a lot for me to process, fairly new to actually messing with circuit boards.

RE: Community repairs?
@Luckypriest Or at least give me recommendations / links for the parts and a friend of mine and I might try to wing it for fun.

RE: Possibly fried duet with an in spec power supply
@bearer its not that its unclear, but when it comes to a project like assisting people with fixing electronics I just didnt think departed. Just thought he helped x amount of time and is no longer helping.

RE: Possibly fried duet with an in spec power supply
@bearer OH NO, so when they said sadly no longer with us, he didnt mean assisting... he meant... That is sad.

RE: Possibly fried duet with an in spec power supply
So @bearer and @droftarts whats the consensus? Think I should hook it up to another PSU and see if more magic smoke comes up?

I'm in the US but would someone be willing to look at my issue?

Also any idea on price for the shipping ETC? We can discuss repair amount once you have the board. This is a sad, sad day.

RE: Possibly fried duet with an in spec power supply
@bearer yeah we had a real bad financial 2 years where all projects sat in one very protected corner of the house locked away from the cats. Initially I fat fingered 2019 in there.
I dont have the balls to power it through the vin again... If I do I'm going to use another power supply but I really shouldnt NEED to as its within spec and working per multimeter.
I'm in the US, they dont love the people here like they do in the EU (assuming thats where the protection rights are in!). I'm also not going to go after a good company like duet for something minor like this but IDK, I'd like to maybe send it to them and if they can show me where I screwed up I'm out haha. But in all seriousness were those pictures finally clear enough to look at everything?

RE: Possibly fried duet with an in spec power supply
it was sitting on my 100% polycarbonate(?) plastic of some sort build plate that I was waiting to try, thats why I'm so dumbfounded. I didnt see anything like bad solder joints on the underside myself, let me get some better pictures.
@bearer Thanks for all your help, seriously.

RE: Possibly fried duet with an in spec power supply
Infrared thermometer reads ~38c on the cpu chip with just USB power.
I'm willing to take the blame, but I really dont see what I did. Is it possible I got a lemon?

RE: Possibly fried duet with an in spec power supply
If that is the case the output was identical, not sure what debugging added to the mix.
-
RE: Possibly fried duet with an in spec power supply
Right but other shorted issues always reference one of those being out, so I just wanted to clarify. When you say try reinstalling after turning on debugging(which succeeded btw), do you mean M997 S1?

RE: Possibly fried duet with an in spec power supply
Also when USB is plugged in both the lights for 3.3v and 5v are on.

RE: Possibly fried duet with an in spec power supply
Interestingly enough, however, after running that the wifi module is disabled, trying to add my SSID gives the message failed to add SSID to remembered list. After that the wireless module is back to always stating that it is being started.

RE: Possibly fried duet with an in spec power supply
It cycled through all the baud rates with me connected and then says installation failed due to comm write error. Was there anything else I needed to do with this?

RE: Possibly fried duet with an in spec power supply
Dont believe I did, the guide I glanced at didnt have that step. Is the server you linked the newest one?

Could that cause something similar?
maybe, ref https://duet3d.dozuki.com/Wiki/USB_ground_loops but still a little odd set of symptoms.
Fascinating read actually, did not know that. Don't think it applies here as it was a laptop anyway.

Found a similar case to mine and walked through the erasing / rewriting the firmware steps which succeeded, followed by:
