Mach4 License file


Mach4 Hobby Motion Control

Mach4 is not designed for a specific motion control device and will need a plugin and motion control board to operate a CNC system. Mach3 was primarily designed for the parallel port which has become obsolete. We do not recommend using the parallel port (without a motion control board) with Mach4 as performance is reduced by both this data connection and the processing and memory power of older computers. 

If you require a system run from the parallel port, you will need to purchase the parallel port legacy plugin.  Art Fenerty helped write this code and he will be thanked directly by your purchase of the legacy plugin for his work and commitment.


The plugins you may need to upgrade a system may not be available and may require the purchase of new hardware. Hardware plugins (drivers) are created and supplied by the hardware manufacturer. Mach3 drivers and code are Not compatible with Mach4.
