Hello all
Iam planning to build a 5 axis cnc for making 3d sculptures in wax or foam. I need a very very accurate machine that can get me very fine details and very smooth surface finish. Iam planning to make it 150cm X axis, 150cm Y axis and 125 cm Z axis. I ned to know which is better to get me the best results, ballscrew, precison rack pinion or belt drive.

Thanks
