I am new to all this, but I have BobCad V21 and the DVD instruction set. I bought a couple of books..David S Hayden's book--7 Easy Steps to BobCad/Cam is quite good and sure has helped me to get the hang of it. I am still learning though. I live in High River and have a SX3 with the Syil CNC Conversion kit. Having some problems with the main motor board right now, but I think there is some light at the end of the tunnel. Have you tried Sorin's videos?
