Open Challenge: Broken Makerbot

Ever since we got our new UP! 3D printer our old Makerbot 3D printer has been sitting on a shelf collecting dust. We benched it because we never got it to print successfully for more than 20-30 minutes at a time and never could figure out what the problem really was with the extruder.

If you're feeling adventurous come in and see if you can fix it! We'll give you unlimtied time with it (during open hours) and as much ABS plastic as you need for it. Should you manage to fix it we'll figure out some kind of prize.
