One problem encountered by new Mach users, aside from the complexity of setting up the machine REQUIRING much use of the manual, is the post processor. Gotta use the roght one or the machine goes nuts.
Vetric programs are great with Mach. A more economical 2 1/2 D pgm is Sheetcam.
Mach is top of the hill, IMHO, and will be loads of fun AFTER a short learning curve!
Good luck and don't be shy about asking specific questions.
