Don't Sheetcam and Cut2d cost more and Sheetcam doesn't provide for the lathe and you need two programs.
Isn't Art working on LazyTurn because turning in LazyCAM doesn't work all that good? Please correct me if I'm wrong.
Now, I don't have a lathe, but I do read a lot of forum posts.
From what I gather, there's very little turning CAM software available to hobbiests, if any at all. Dolphin has a package, but I believe it's $400-$500 for hobbiests? Not 100% sure on the price.
"I have not found, as of this writing, a basic CAM program for the mill and LATHE which has a good manual, excellent knowledgeable support, and provides the level of CAM capability directly into MACH for the cost of the license."
Now, if you leave lathe out, as Ray said, Cut2D and SheetCAM blow LazyCAM out of the water. And you won't find anything easier to use than Cut2D.
But, if you need to buy an additional Lathe package in addition to one of those two, then cost becomes a huge factor.
My Bottom line, is this. If LazyCAM does what you want, consistently, without problems, then , by all means pay for it. If you can't work with it, or you need additional functionality, then buy something else.
At CNC Zone, people always ask "What CAM software should they buy?". My answer is always to try all the demos, learn how to use them, and buy what works for them.
