Watch out for the first paragraph in the link.

He has his description of the Right Hand Rule all screwed up.

Most of the diagrams I have found have the tool on the backside of the chuck which is even more confusing.

Z- is towards the chuck, Z+ away from the chuck.
X- towards the work piece, X+ away.

If your tool is rear mounted, Mach3 should take care of reversing the X axis so that X- is still towards the work piece.

Thanks for the replies, Peter's answer was probably the most helpful, as in keep it simple stupid! (for me) I have just got the coordinates into my head for my mill and then was confused by the online info, as Greg said it was buggered up.
I still would be interested to hear from any other CNC lathe owners out there.
