Bummer Richard,
You might post a new thread, so that MACTEC chimes in. I seem to remember his concern about ball screw alignment on the Z axis.
Sounds like its going to be quite a job. Keep us posted on your progress.
Take pics and video if you can for the rest of us in case we have to "cross that bridge"
