Thanks and no offence is intended to everyone.

I apologise for asking questions and from the responses I assumed that no one had actually tried the software?

Maybe I am wrong to assume that a piece of software was actually capable of what it is intended for.

I have to start somewhere, I like the way it quickly creates what you want and that's what I was looking for.

I will wind back the speeds and feed rates and depth of cut per pass until I get to where the machine behaves and cuts like I expect it to.

I do appreciate the comments, but until I start having a go, I will never learn anything.

A problem is not a problem, it's a solution waiting to be discovered
