I'm having an issue with my Ultimaker 2. I had a print running that quoted 21 hours to finish. About 1/3 of the way through, the filament ran out and I did not catch it. So it continued to "print" for about 14 hours with no filament running through the nozzle.
Since then, I cannot get the printer to print. The filament will not stick to the plate on the first layer.
I've done several Atomic Method cleanings in the nozzle, i've releveled the build plate several times, and reinstalled the filament a number of times as well.
