Never had an issue saving to where I wanted so not sure whats going on there.
Not sure what you mean with "next it dose not show which processor is for an inside or outside profile", the post processor will do both internal and external. The difference between the two Mach 3 post processors from Dolphin is one is for Radius mode the other Diameter.
Never had an issue with starting where I wanted either, its very configurable and you can tell it to strat and finish at exact positions if you wish.
Have you had a look at the tutorial video and the manual?
