Hi Jazz,

That is an interesting thought, but I intend the use the capabilities of the cnc as well actually quite a bit including 3d roughing and as mentioned earlier would like to add a 4th axes later if this works out alright.

Here are a couple of pictures of similar machines that I have used as reference. The one on the picture is a rack and pinion system and has been working for the past 9 years generally for about 6 hours a day. And it has a surprising setup that blew my mind and in a way made me confident in my design. It has only three HIWIN blocks on the y and also just three on the z. On the Y there are 2 on the front and one on the top and on the z two on one side and one on the other :)

I do a lot of logos in ice which would be done with the cnc. At the moment I do them by hand and it was ok until now, but now that I know that I am designing a cnc I cant stop thinking about how easy it would be :)

Thanks again for the great advice.
