My Z-axis is way too stiff, so I ended up here (like, I suspect, about 50% of people building these things).

After removing the wood panel at the top and loosening the drive connector at the bottom, My Z axis threaded shaft sits at quite an angle to the smooth one next to it. See http://i.imgur.com/HU7mERN.jpg. I can get it into the hole, but having done that it's so stiff the motor can't turn it. It's not bent, it's just going through a thing which is clearly not parallel to it's sister.

I'm not really sure what to do about it, other than grab a pair of pliers and try to bend everything to a reasonable angle. Ideas welcome.

You think well.
There is no other option but you have to model a black handle with a trapezoidal nut.
I had a similar problem but to a lesser extent.
On the forum I help to use the rod, I don't give fish.

I had this problem to,
after a lot of testing I realized that all I had to do was loosen the bearings for both the smooth rod and the threaded rod.
