If you're currently using one of our Z-independent dust boots with your Onefinity CNC machine featuring the Z-16 carriage. 

Then your bracketing looks a little something like this:

If you're wanting to upgrade to the new Onefinity Z-20 carriage, you will need to purchase the updated bracketing system:

Most notable changes:

1. Thumb screws have been lengthened so the thumb part is in a better position relative to the updated spindle mount.
2. The upper support arms have been thickened for the same reason.
3. The nut-plate has been narrowed to better fit into the thinner track brackets built into the updated Z-20 carriage.

There is no upgrade kit as there are too many changes to the bracketing in order to accommodate the updated carriage design.
