If anyone is still interested in building their own CNC machine check out www.instructables.com
The site is all DIYers posting tutorials on their projects. Everything from bread recipes to nuclear fusion, (seriously, www.instructables.com/id/Build-A-Fusion-Reactor/
that'll put the fear of Jesus into your neighbors!). Put in CNC in the search under technology and the gates will be opened to you!
Lots of great, (and not so great), gadgets and hacks and such. Projectmania Rules!!
