BTW just download and install, it doesnt cost you anything to try it out. You can even install Mach2 as well, just cant run Mach2 and 3 at the same time. Have a look at the tutorial videos as well, they help a lot when you are new to Mach and although they are referring to Mach3 they will also give you pointers if you want to set up Mach2 as well.
