Is there any other test I can do? At the moment its looking more and more like a processor failure.
The board is less than 1 year old. Only purchased in July last year so confused as to why the processor has failed. There seems to be no other evidence of a short as everything which should have failed first is still working.
Please can someone advise the best option to get this card operational again as I need the printer in the very near future.
Thanks
@dc42 I can only check by touch as I have no other tools available.
The regulators are cool to the touch. The wifi module and sd card reader are warm only but can easily be held. The processor can only be touched for 3-4 seconds.
Hope this vaguely helps
Ok. I have been through my wiring again with a fine tooth-comb and can not find any shorts anywhere. I have double check all connections and again can not find any 24v or even 5v shorts to the 3.3v rail.
What else could be causing this?
I have followed that guide twice now with no luck. I can not see any damage to the board.
I have some basic electrical knowledge including some semi basic pcb assembly for my model railway including a cbus system. The hot processor is suggesting its been damaged somehow and I can only think of a short somewhere.
Hi all,
My Duet Board suffered a fault over Christmas and will now not boot up. I have disconnected everything and tried to connect it to my pc via the usb thinking its a firmware issue but even there it will not be recognised.
I have tried to erase the board and put a fresh copy of the firmware on but still can not connect it to my pc.
The only thing I have noticed is that the processor is getting very hot even under 5v usb power.
It was installed in my highly modified CR10S-pro and suspect it may have suffered a short somewhere. I have checked the external wiring and can not find any issues. The board is less then 1 year old and I need to get my printer back up and running.
Please can someone give me pointers to get it operational again. Thanks
