I was confused about how this worked.
Looking on the comments on Thingiverse, the consensus seems to be that on one side of the Z (carriage), the drive nut(s) have been removed, and a secondary module has been added under the carriage, so that the existing carriage rests on the new carriage.
There seems to be a contact on the base of the original carriage and the top of the new carriage.
When the Z goes down, at some point, the nozzle touches the bed and takes the weight off the Z carriages, but the new carriage continues down, as its the original carriage has been disconnected from the threaded rod.
This causes the contact between the top of the new carriage and the underside of the main carriage to break the electrical circuit.

Thanks for that explanation, I get it now. It seems to me that an added benefit of a design like this is that the head can never be forced into the bed. Is the contact wired into the Z end stop trigger? If so this seems like a pretty easy design element that could be added to a lot of printers.
Radus, great job on your design.
