I've been to about 25 INDUSTRIAL woodworking shows over the last 4 years and I know a lot of the router guys pretty well since I ask so many questions. I know there's a big difference there, but because I know about those machines, I know where I want to go with this ... eventually.
Maybe I can contribute a little bit to this hobby's more advaneced features once I get into this. Ken Susnjara, which is the president of thermwood, has a great book about advanced features of CNC routers that may be helpful to a few of you who are wanting to expand upon your designs. His son gave me a copy a couple of years ago, but I think he sells the books for $25 a piece.

He rambles a little bit about thermwood's history and other things, but there are several parts about screw harmonics, error checking, and other types of topics that might help out a bit.
