I knew I didn't have enough filament to finish my print, but there wasn't enough to bother stopping the print and save it so I let my R2 run overnight figuring that I could just cancel it from the pause screen this morning. I came down stairs to see that my printer was totally dead. The power strip was on, the power supply is lit up, the switch on the back is in the on position, but the printer itself was frozen, and the screen was black (like it is when it's totally shut down.) The filament spool was jammed up against the run out detector because the filament didn't release like it was supposed to, but I've seen it do that many times and it hasn't totally shut the printer down before. I got the spool off and then tried flipping the power switch a couple times. Nothing. I unplugged the power supply, let it power down, and then plugged it back in. Nothing changed on the printer. I did notice that the power supply was making a higher pitched whine than normal after I plugged it back in. Has anyone had an issue like this before?
