With a worm drive gear you probably can't remove it all. What fragger is saying is that unless you are precision machining wine barrels the backlash you can get to may be well within tolerance. Also you can design the cut to force the work in the direction that backlash is already taken up from. I see many folks seem to rate the stepper high enough to drive the table with the locks dragging which helps to add more resistance to the table shifting in it's backlash
