After finishing my printstruder (you can never have too many spare parts) I lowered the one warped Z axis threaded rod.  I probably lowered it about 1mm farther than it was before I had raised it to install the Z axis crank.

I guess sometimes that kind of thing makes a difference.  I’m watching my little ‘bot print up something right now… and it’s looking fantastic.  So far there’s no hint of the former regular but slight shift that you can see on the TARDIS and Dalek.  Mind, the TARDIS and Dalek are some of my best prints.  Anyhow, this is truly encouraging – with a nigh elimination of this warp, I am that much closer to printing precision parts.

One of the members on the MakerBot Operators group has posted his process for calibrating his ‘bot and adjusting Skeinforge settings.  It appears ridiculously thorough and I’m looking forward to trying it out.
