Hi Guys,

Having been keeping an eye on the market for a 3D printer that meets my requirements, I'm thinking of building my own (how hard can it be? ;) ).

Anyway I have a rough frame/gantry design in Sketchup (will post the skp and pics when I have finished), but I'm also thinking about what steppers to use.

From other machines I'm thinking Nema 17's should be sufficient, as I'm interested in speed rather than torque? Also what pitch/diameter ballscrews to use?

Oh and whilst I remember I'm looking at a build volume of roughly 500x500x500mm.

Cheers

Chris
