Mach3 is a powerful CNC machine controller software.

It generates motion from standard G-code and has many options.

Mach runs under Windows Operation system and the interface is the standard parallel port, no external hardware device is required to run your machine.
 
Mach3 has been the back bone of hobby CNC machines for the last decade, there is lots of support, macros, screen sets, post processors and plugsin avalible and is still a good choice for a low cost motion control software package.
