Thanks for the help guys, it is much appreciated.
Here is what I have decided to do, and need your opinions on this course of action, as well as recommendations for the proper equipment.
1. Change from Vista to XP , either home edition or PRO, whichever is recommended.
2. Purchase a new 4 axis controller that will work with MACH3 and my stepper motors.
I would appreciate any and all advice, and entertain buying a controller from someone here on the forum that has one compatible with my motors.
Best regards
BP
