Does the extruder turn without filiment installed?

Have you tried plugging it into the port for the x or y axis motor to verify that the stepper motor on the extruder is Ok?
What about swapping the motor controller from one of the other motors for the extruders controller?
Have you checked the voltage being sent to the extruder motor?

Not sure if this will help but I had the same probelm with my Makerbot and discovered that it was due to my filament spool snagging on the spool holder. It would streach the filament then push more through causing the blockage. That could also explain why when hand feeding it it worked well. 3d printing -fdm technology



This could be complete rubbish but thought it might help as I spent 3 days, meters of filament and burnt fingers on trying to find out why.
