Well I finally feel like Ive got a decent start. I spent the weekend and this afternoon finishing up the Z axis, so now all thats left is the X and Y screws, and a control system. It has been fun, but dont let anyone fool you, this type of machine takes a lot of patience and hard work. I have pics of the whole build to date, I will add them as I have time. Here is how it sits at this point.
