really budget first cnc

[jwest]

hey, as part of a college project I've decided to undertake the task of designing and building a cnc router. The project is funded by the college so money isn't an issue, but i think it would be a much more exciting challenge to build it for the very bare minimum, so I'm looking for any ideas that can keep the cost down, so far I'm thinking.

75cm (30") by 50cm (20") cutting area, and a few inches in the z.

Having a stationery gantry, the workpiece moves instead, i think this will be cheaper as the workpiece could be clamped down to a really small base, simply a bar that slides on rods at either side.

X,Y and possibly Z will use timing belts and pulleys, and only 1 motor on the X.

Construction mostly of plastic should keep costs down as well.

Obviously I'm new to all this so any suggestions at all, would be really helpful.

Thanks
