Best advice I can give is talk to Jazz. Could save you a whole lot of expense and agro. Have spoken and emailed jazz a fair bit and he certainly knows about cnc machines.I would grab his offer for help as it is a rare thing nowadays for someone to offer to pass on their hard earned knowledge.
Jazz is extremely helpful and has a refreshingly no Bullsh*t approach. If you do take him up on his offer of help, please remember that Jazz and other knowledgeable members of this board impart their considerable knowledge and help at the expense of their own time so please respect that.
