It gives you a bigger working envelop over the X2. Furthermore, you are able to have a CNC-ready table (x and y) for little more than the cost of conversion kits on the market, and total cost of a CNCbridges solution (including the z attached to the X2 mill head and column) is below the cost of a new X2 converted to CNC using a 3rd party kit (CNCBridges, Steele, and KDN).
But no one really knows how rigid the set up will be since no one has one yet. So it would all be speculation at this point. The guys on the buy list will be the first but it appears that Harlow is still engineering his product as people provide wants/needs to him.
Harlow, you are an engineer first aren't you Good man.
FWIW,
