If you have a good control SW, than you can enter a turn of your part in each axe.
But thats not as good as you clamp your part parallel to X-Z.
You'll see the small steps, when the control correct the position, against a move only in 1 axe.
And a autoleveller works best with a switched 3D-Tester, because you can move, and the control automatically stops and take the measure if the switch is actuated.
With a manually operated tool you must take over each measure manually.
