UPDATE 28 Feb 2018
The Z-Axis end stops are different to the previous model and the screw centres are different. The 2018 Model has an extra hole for attaching the newer end stop.
V4 has been replaced with V5
V4 is the pink one, V5 is the green one :)
I added an Ultrabase surface to my print bed and the built in adjustment was not fine enough.
I used the existing metal bracket with some longer M3 screws to fasten the bracket to the frame. 10mm Works fine
