Ah I don't think Zapp do the kit I bought anymore and the closest to mine is the High Voltage 3 Axis one here: High Voltage Digital Driver Kit (Four axis)

The description has an error as this is actually the 3 Axis kit using DM856 drivers (mine was an earlier analogue version using AM752 drivers).

If you are going to cut wood only (I cut a lot of aluminium) then you maybe able to use the lower voltage kit - others will be able to advise.

As Jazz says though - the electronics is something further down the track - get the frame, gantry, ballscrews, rails, bearings etc. sorted out first.
