That is tough to do with a vertical head. You lift the head to raise it a little then you have to lower into the work. This puts the backlash on the wrong side.

I was wondering about how gravity affects this situation.
If the lead screw is taking the weight of the motor and spindle and basically controlling the descent then any backlash would be upward.
This would seem to introduce an uncontrolled variable in an otherwise very precise machine.
Conversely if the lead screw is pushing the motor and spindle down then there would be no backlash except when raised.
Or am I thinking about it wrong?
