When printing with my lulzbot mini, it worked the first 25 prints or so. This morning when I tried to print something, all of the filament that comes out just sticks to the nozzle and not the print bed. And the little amount that does stick to the print bed just gets shaken off. I am printing with black 3mm ABS. Extruder Temp: 240 Bed Temp: 110. Someone, anyone PLEASE help!
