Im Just a mirror my friend, i was just trying to clarify what you knew as you have few posts and as we get machinists from expert to never touched a spanner, the answer to your question is this, i decided to keep with the moving gantry design, even though there may be a requirement for larger motors, and more complex design, the effective working area and space needed sold it for me(7'X4'). But then with a design as small as yours i may have been tempted to go for the moving work area as The mass being moved would mean faster machining speeds, the chap to ask is jonathan as he has experience of both small and large machines alike although im not sure about the moving X in his case..
