Hard to see, but it seems as if the motor shaft is not turning at all...is that correct?

I have to say i'm finally impressed with SD.  They called me back just as I shared this video and are going to be sending me a new motor.

Awesome!  I was going to say that if you checked the wiring back to the board and did not find any shorts, etc. that it is probably the motor...

Keep us posted!

the difference in your ability to spin the motor smoothly based on position would in fact indicate a shorting out of the motors coil pairs...you may want to inspect the wiring harness more closely...

Makerbot is going through a class action lawsuit for "their knowledge of faulty 'smart' extruders".

Back on topic though, glad to hear you're back up. Let us know how it turns out

Seems to be printing smoothly again.  I'll inform everyone if otherwise.  This printer is great, but the maintenance required is sometimes aggravatingly pointless. 

Are the Makerbots really so seamless that they would require less maintenance?

1) Extrude while sitting on the right side and flex the wires. If it retracts, you have a short.
2) Swap your Y and E motors. If you face the same issue with a proven to work motor, it is a software problem.
