Background: The Z axis on a delta isn't reliable for getting the current position. However, the distance moved can be determined and added to the start position to get the real final position. This is the method used in the past, but it was glossed over in recent updates to the probe functions.
This PR reverts to the original method. An alternative method using Delta Forward Kinematics is pending, which will also allow fixing the position after a quick-stop.
