Let The Fun Begain, New build on the Table.

[Ross77]

Apologies if my comments seem harsh, I am only trying to help you make your machine as strong as possible and easier to build.

My Machine is still on the drawing board and is way different from yours anyway. if I get time I will sketch some thing out for you.

I've attached a design I started 4 years ago but abandoned as I needed a stronger machine, you might be able to adapt afew bits. The z axis has the one piece top and bottom plate I was talking about and also the raised x axis rails might suit your design as it makes the gantry shorter and still gives a good depth of cut. Its not a finished design so I know its not perfect.

That can be done, however you need to be careful not to have the ballscrew far from the Y-rails and spindle, otherwise the stiffness of the axis will be greatly reduced.

That was my thought as well, you would place the ball screw under unnecessary load by having the link bar go around the beam to the z axis. better to cover the ball screw with bellows. Or if you make the c section deeper to increase the y axis rails then the ball screw could be moved to the top so out of the way of chips.

Happy building
