Why is this happening to my prints?

Geoff, I think the line showed up on the layer that has a flat surface. On the hexagonal infill layers the shell looks good, but then once it hits that outer layer (roof?), I noticed the nozzle plowing through the infill and I think that's where we see the defect. The hinge from the first set of pics was @ 100% infill, whereas the second was something like 30%. As far as firmware version, I think the LCD reads PowerSpec 3D Pro v1.2 on startup and Skeinforge sees it as a Sailfish firmware, but I'll have to go back and check tomorrow. I'll also try the hinge again in a different location/rotation and see what happens.

RobH2, I played around with the feedDiameter and currently have it jacked up to 1.90mm and managed to print an OK-looking Marvin. Probably should be changing the feedstockMultiplier instead, but I've read conflicting accounts of whether to increment or decrement that variable to reduce the amount of extruded plastic. Which slicer are you using? I'm actually thinking about upgrading to Simplify3D soon based on all the glowing reviews.

EDIT:
Was looking at the wrong side of the hinge, I see what you meant, Geoff, about the first 10 layers or so...then the line. Still not sure what the cause is, maybe those layers were are at 100% infill and the problem gets compounded by layer ~10?
