After spending more than 2 days on this project  I have decided to take a new approach.    My neighbor gave me 3 Dell laptop computers, made in late 2005, loaded with WIN XP.    My plan is to load one computer with Windows 7 so it will match the Smooth Stepper instruction manual.
I'll get the laptop connected to wireless internet then load MACH3.    Then I'll have a bare bones computer with on an operating system and MACH3.
What I have now is a used computer with countless settings made by the previous owner.    Since I'm not an expert, I have know ideal which settings apply to my application.
