I think that when you press Go To Work Zero, for example, the machine should move the Z axis independently from the others. If targetZ < curZ, then X/Y should move first since it might happen that the curZ position is set to avoid obstacles (holding screws?). Vice versa, when targetZ > curZ, this axis should move first in order to raise the bit from the surface (drill bit in a hole?).
Is this crazy?

Similar to issue #181
With a customizable button, both cases can be covered by moving to a safe Z height before going to the zero position.
This will be available in 1.9.8 soon.
