First off you want the z-axis to hang by it's own weight - this is the mechanism that Taig uses to take up the backlash in the z-axis. If the z-axis is too tight then you will have backlash.
Have you played with the shoes on the side of the z-axis that clamps it to the slide back to front? You may find you need to adjust those as well.
What controller are you using? The Taig one or an aftermarket controller?
What are your rapid speeds set at?
