Found this site: http://www.jjjtrain.com/vms/index.html
This site was designed to provide manuals for ALL types of Machine work including CNC.
I am in the process of learing how to use a Metal Lathe/Milling machine and the information on this site is helping me immensly...
The section on CNC is great.. check it out..
Looks like it could be useful, thanks for the link.
