This is my journey on building a rack and pinion Ox variant called the F-117 CNC.

The X/Y table system is a great starting point for many CNC projects giving you the ability to move an object on the X and Y axis in a simple compact style.

This is a router that I designed that is loosely based on the Openbuilds Ox, but designed to be heavy duty, rigid, and yet quick and agile.

This project shows how to use Openbuilds Vv slot extrusions and wheels to retrofit a Lulzbot Taz 4 or 5 printer. These modifications improve layer consistency, eliminate nozzle and bed sag, and allow for larger toolhead mounting.
