I asked the same question to be sure and here is the reply:

The 1000mm rail kit comes with all the brackets, extrusions, and hardware to build the frame. The hardware to mount the wasteboard to the frame are in the wasteboard kit.
We will not have the dw611 mount for a couple of months.

Looking at the build instructions, people should add :
2 packs of 10 Pre Assembly insertion nuts 25281-02 and
2 packs of 10 button head cap screws 25286-15 20mm M5
so you have what you need to bolt your own waste board down.
