@bearer Thanks for the help.

@bearer Sorry wrong of me. The leds that are on all the time is Diag, USB Power (when USB cable is connected) 3.3v, 5v and VIN (when 12v/24v is connected). The problem is that Diag led is on all the time.

Yesterday i started up the printer and nothing happend. Looked att the board and all leds are on, not the wifi led. Cant connect to pc via the usb cable. Nothing shows up in device manager. Nothing happens when i press the reset button. Nothing happens when i tried and erase. Same thing with the usb and with a 12v supply. No componets are hot, the card is just dead. Luckely i had a spare Duet 2 wifi but i want this one to work to. I now have two dead duet 2 wifi boards. Please help!

@droftarts i ment that i dont know if it is just the E0 that is faulty or if it is more. I dont have the knowledge to check if something else is wrong.

@droftarts but can i disable the voltage to E0 or else it will go hot all the time?

@dc42 Its just the E0 that gets hot. But i have no idea if something else is wrong with it. Dont know if there is a workshop around here with a hot air station. Have no idea what the cost is to send from Sweden to UK. Just frustrating that it is a brand new board.

@elmoret bought it from reprappro.me

@timcurtis67 im in Sweden

Ok so i have a brand new duet 2 wifi and my problem is that i had a short in my extruder cable. Now i get error on the drivers and the extruder driver chip gets very hot. I know i now have a short or several shots on the board. But i wonder if it is possible to save the card or just throw it in the trash. Thanks!
