Re: 5-Axis help

No. I did not take your comments as being harsh at all. I respect
honesty. As for the type of material being milled, I have no plans on
milling any metal. My work will mostly be done in clay, styrofoam,
and occasionally plastic and wood (i know plastic and wood may be
pushing it). I would imagine that the aluminum frame should handle
this although I would like it as accurate as possible...of course.
The machine I used as an example is just that; an example. I do not
want to build anything on that scale. That is definitely over my head.
I really appreciate your comments Jon. Keep 'em coming.
