SD Card Smoked and Burned

Maybe try firmware recovery but its a long shot.
If anything on the board feels hot when running of USB then stop.
Btw, just lighting or a hole?

Ah yeah good catch i did not see that! Looks like a hole to me.
I have tried 2 usb cables 2 computers and no dice on connectivity.

yeah, long shot. with a hole in U10 you woulnd't be able to run motors no matter what happened; odds are you'll need a couple of chips replaced.

Yeah trying the instructions when i jumper the erase pin i do not get the diag light and then the board starts smelling hot. the large chip becomes hot to the touch.

Just wanted to post an update. i have re-installed my old controller (Rambo) and swapped back all of my electronics and nothing seems a miss. I want to point out i had not changed any 5v connectors during the swap to or from the duet and i did not install or move any 24v connectors (bed,hotend) while the system was powered on.

whelp it was a good run. I had my replacement running for a bit. I recently started having an issue with filament snapping so I decided to add a filament monitoring switch. 2 wire setup going from ground to e1 stop no center pin. I plugged it in and e1 fan started running. suddenly i noticed the wifi had no power. I unplugged the switch and reset the board still no wifi power led. I plugged in USB and nothing. This seems like exactly the symptoms as last time except I did not get a smoking hole in an SD card. Also happen right around when I hooked up my 3rd end stop.

@skywurz
probably the endstop pinning is different between Ramps/Rambo-stuff and duet2 ?
Here's the duet2 wiring diagram -

What is the endstop switch exactly and how exactly was it connected? Photos?
Which fan do you mean exactly by e1 fan? Fan ports are fan0, fan1, fan2, and always on.
