I'm having issues making a print of just about any significant height. The Makerbot goes about its business just fine, until it hits some random height (it varies), at which point it starts printing at an offset. See the pictures if you're having a hard time understanding. The print does not slip: it's still reasonable stuck on after everything is done. I don't think it's a calibration issue either, because it prints fine up to a certain point.
Any thoughts?
I have the Thingomatic, MK6+ with ABP, using 1.75mm ABS plastic. I'm running the latest Replicatorg (26) and Skeinforge 35.
This was supposed to be from the screwless cube gears, bgear1

This is supposed to be Stephen Colbert, not an alien :)
