You said you installed the toolpath software - did you install any CNC control software, like Mach3 or UCCNC? Tool path (CAM) software opens your drawing or model and writes a tool path (G-code) program that tells the CNC control software how to cut your part. But it doesn't execute it. If you have a 32-bit Windows 7 computer with a parallel port, you should be able to get Mach3 to work. But if you don't have a parallel port, or are running a 64-bit version of Windows, then you'll need an adapter/motion controller to run it from another port, like ethernet or USB. .
