good day all

Its been a while since i haven't posted anything. After reading a lot more threads i realized i was getting ahead of myself. I have worked on the design a little bit see pics. Also i have decided to put a 4th axis. But this is something i will need help in applying it to my current design. I don't know how to upload my sketch-up to the site. Have a look and tell me what you all think.

If @ all possible ie budget wise i would change your linear rail system to Hiwin or similar profile. X axis top rail put another two pieces (each side) between frame to brace. Z axis it is best practice to use the rails on the front plate to provide additional support.
