No. The one I have the effector is in two bits, and a hinge is formed by having a rod go through from one arm mount to the other on one side. The part that holds the hot end can then pivot up a little and this is detected by the optical sensor. So I uses the tip of the hot end as the z probe.
I just can't find stl's anywhere for this part.
I'll see if makergeeks can provide the stl files.
