I personally don't have any experience with converting as i don't generally do this work being as i am in industry. What i can tell you/show you what industry does for this mod, be it a dedicated cnc knee type carcase or a retro fit of a manual machine. This mod only ever uses the quill as the z axis. I have never personally seen the knee being used as an axis. Effectively if you cnc the quill and knee you are making 4 axis machine where 2 axis do a similar job. The quill is the way to go.

If can remember and have the time i will take some images of one of my machines with the covers off to show the z quill arrangement. I know exactly how its set up and and can describe it to you but as always images speak a thousand words.


Kind regards,



Scott, ward engineering.
