I would also recommend Steve Dunthorpe’s book “Blurring the edges”. It does give a pretty good guide to installing and using a Tormach 770MX.
I have a Tormach 1100M which I bought about three years ago from CNC Machine Tools who are based in Snetterton in Norfolk. I think they are still UK agents for Tormach. The guy I dealt with was called Connor I think. I’ve put a link at the end of the message.
I have been very happy with my Tormach, it is a very capable machine, and having used a lot of CNC controllers over the years I have to say I really like Pathpilot. You are very welcome to have a look at it, but unfortunately I’m in Scotland (near Perth) so probably a bit far from Yorkshire.
