Hi Robin,
CNC machining is a bit like computers. Went you first get involved you are paranoid about the hardware then, after a while it suddenly dawns on you that really what counts is the software. You've just reached that point, congratulations.
Good software is one of the most important asset you will buy for your CNC machine and it doesn't need to cost so much.
Regards
Phil
PS: I remember many years ago developing my own computer program that would perform calculates based on an input/output matrix table. After 3 months of effort somebody showed me a new, commercially available piece of software called a Spread Sheet.
