Hi all, first time posting here.
Here is a pdf with my design for a small 3-axis cutter for cutting model airplane parts with a dremel. The drawing is not complete yet just what I had time to draw up while I was at work . I plan on using timing belt to move the X (i think) dirrection. As for Y and Z not sure yet how I am going to move thoes. The bed size is 16X14. let me know what you gys think, all comments welcome.

As for the interface card i'm going to be building this card:http://webpages.charter.net/pminmo/cncelectronics.htm
the first one. I was going to start making the board tonight by silk screening it (my day job) and etching it,but I have seen other people say that Bipolar is better? If it is better any good links that show how to build one?

I can see the pdf but there isn't much there to comment on really. Belts are nice and a good idea to drive on both sides as you have. Can't quite work out your rails, are they bearings running on steel flat?

Good bipolar drivers here:

Or buy a Xylotex unit.

You might want to be a little more specific to get a response.
