Yesterday, I got my UM3, and after I set the machine up I saw that there was a firmware update that the machine could install by itself. The UI was rather sluggish, so I decided to let it update to see if it helped. I came back later to see that the screen had gone black, and the print cores were glowing as if they were in a cooling cycle. After an hour, I realized that waiting wouldn't do any good, so I rebooted the machine, and everything was fine - It installed a motion control package and then went back to normal. Satisfied, I turned off the machine and went to bed. I turned the power switch on this morning, and after hearing a fan turn on and quickly back off, the machine did nothing. I've tried everything I can think of, (including unplugging everything and plugging the UM3 in again), but nothing has worked. The fans still turn on for a second when I turn on the power switch, but that's the end of it. What should I do?
Thanks for reading.
Update:
This problem was solved by removing the wifi board (under the cover for the Olimex boards). I still don't know why, but that's fixed everything.
