I was considering the concept before of a belt driven Z axis. To eliminate the drop when the motors are not powered, I was thinking along the lines of a worm gear drive. The Z axis is the slowest axis anyway, and something on the order of a 1:4 to 1:8 worm drive should be quite suitable. The worm gear will have a small amount of backlash, but should not be a problem in this configuration.
