OK I figured this out. It turns out that there were a couple of loose screws on the extrusion unit and after tightening the problem is gone away. This is not the first time that loose screws were the culprit. Is there a way to keep the screws tight on the ultimaker?

I'm getting close to the end of the filament reel and noticed that the tension might be causing the extruder to malfunction and stop extruding. More specifically, the bolts holding the extruder together are loosened and the gray plastic nut holding the filament in place (pressing against the extruder gear) is out of place. Has anyone have similar problems and what is the solution since I'd like to use the whole reel of filament. Thanks in advance for your help. hxorn00b

I was printing the Venus head and it was fine until up to about middle of print then the extrusion stopped. I figured it was a normal blockage and tried to extrude by hand after cutting off the deformed tip of the filament and it was able to extrude. Then I restarted the printing only to have it stop extruding again. Does this sound like a blockage that requires disassembly of the hot end? I am hesitant to do the disassembly. Also how to prevent the extrusion from stopping in the middle of a long print? Is there a way to restart where it stopped? Thanks for help in advance.

Hi concreteturtle, how would you compare the ulticontroller with cura for ease of use and quality? I'm finally starting to get some decent prints with cura and so quite hesitant to shake things up. Thanks in advance for any tips you may have.
