Y Carrage linear bearing upgrade for the Robo3d.

This is my work in progress to replace the drawer slider design with a linear bearing Y stage on the Robo3d.

This upgrade has had a major improvement on my print quality.

rods are cut from .375 ground polished 316 stainless rods. available from http://www.metalsupermarkets.com/Material.aspx?ProductId=SR316/38

im still working on the drill guide. its probably going to be part of my next upgrade to reduce the deck height and wiring harness replacement.
