This summer, I am planning on building a CNC mill. Along with being functional, I would also like it to be cheap. I don't know how to weld, and don't have access to a welder, so I am making the framework out of MDF. I don't know much about building a CNC, but with what I found online, I think that I have a usable plan.

To see if my design was theoretically possible, I modeled the whole thing in Inventor, before I began making purchases.
