Simon,
I tried the lathe module out and it is nice. The hobby price is a bit steep $400 or so.
The problem with it is, ..........the same as any other program. You need to think in terms of how you are
going to do the machining, be able to apply the lathe tooling appropriately, have your machine somewhat automated.
If your not setup, say to use repeatable quick change tool holders or an automated tool changer.....then your back to a a semi- auto / manual operation of the machine and don't fully utilize the software.
That said, you can do all the same work using LazyTurn and Lazycam Turn. So if your a hobbiest, $75 sounds so much better.
I did find Dolphin lathe to be intuitive and easy to use. I also found it had problems with pathing on some of the stuff that i tested LazyTurn with. It's good but only as good as the user using the tool!
So i would suggest you try out Lazyturn and LazyCam ( both have a manual ). If your in a buisness then skip those
since they are not meant to compete with high end stuff.
