No problem! I've been inspired by this thread so thanks to OG!
Hoss has got a lot of info on his site but it's a little unorganized. This page was pretty useful to me in understanding what the electrical side of things looked like http://www.g0704.com/G0704_electronics.html
I was on my phone earlier here's his monster thread on cnczone
http://www.cnczone.com/forums/benchtop_machines/111863-hosss_g0704.html
It took me days to read it all, but it was worth it.
His is certainly not the only way to cnc a g0704 but he's done a lot of trial and error for the rest of us for sure.
This is another thread by a benos guy http://www.cnczone.com/forums/benchtop_machines/122462-pm-45_computer-numeric-control_conversion_rf45.html
Not a g0704 but still a great thread on a beautiful cnc build. A lot to learn in there too.
I hope to order my mill this week and have working cnc by the middle of next year. That's my plan anyway, the more I've read the more I've realized how complex the build CAN be. StraightUp's build was AWESOME!!!
Take care
Kevin
