Lathes work differently from mills. I'm a big fan of DeskProto (and a distributor) but I don't think it will generate the right kind of code to run your lathe. On the other hand, there's plenty of other lathe CAM software that should work with your machine, like VisualTurn from Mecsoft (which we also sell). I've never heard of a CNC lathe that was tied to one particular brand of CAM software, although it may be that your manufacturer is only familiar with that one.
