Markus,
Thanks for pointing that out. I guess it never occured to me that the plan weren't available world wide. As one who has done a lot of international business, I sort of take things for granted that everyone does. My apologies for not catching the source of the email and checking the kleinbauer website for details. This is something I will start doing.

As far as a DIY machine, I'm still debating whether to follow John's lead and search out window channel, or to scrap a couple wide carriage printers and use the linear bearing and slide arrangement. Considering how abrasive FR4 is, I'm not sure which would hold up better, but I'm thinking the plastic guides on window channel may be the best as the surface area is much greater.

If I were to build a machine for heavy duty 3D use, rather than just drilling, I would probably use dovetails with a ball screw drive system. However sourcing the parts surplus could take quite a while.
