Describe the bug Had a print this night, first layer wasnt ideal, but did not look that bad. I let him continue in the hope of "recovery", dont need it beauty. :) Bad luck, it did not succeed. This morning is saw "crash detected", printer asked me "continue or stop". I chose stop, since it looked pretty bad.. Bed was heated, but the nozzle was "cold".. Then it wanted to unload the filament (I didnt noticed the cold nozzle yet) and hit yes.. You can imagine what happened, nothing! loud sound, gears melting the stuck filament ^^

To Reproduce Hard

Expected behavior If user hits yes, unload, .. check if the nozzle is hot though! ;) if not, heat :))
