I am printing and 5 hours in, the printer powers off. It recovered when I cycled the switch and it seemed to finish OK but now it dies every time I try to print something. During the preheat for PLA it dies, every time. I cannot use the printer. Also, I noticed the light in the switch is no longer working and during the last power cycle, at the point of reset, the light blinked. It is probably the switch. I do not want to void the warranty or anything like that so please advise me how to proceed.
