I have recently started designing a few bits and pieces for my next CNC build.

I have opted, for ballscrews on all axis.
Hiwin style linear guides all around.
Servoes from DMM-Tech.com on all axis.
And a heavy duty z axis, for optimal stability.

I will be using a UNP steel beam for my Gantry so it should be very sturdy.
All flat surfaces for mounting will be machined so everything will be perfectly angled.

I have for now, only made a few renderings of the gantry main beam, including the servo and the hiwins.
This will be mostly a design build, and after complete design has been made, then I will start building it. ENJOY
