Mach3 is very popular software used to control your CNC machine. Traditionally, Mach3 made use of the parallel port of the PC to communicate to the breakout board. Since parallel ports phased out on PCs, the parallel port interface was replaced by USB. This is where this Mach3 USB breakout board is used.

This board can drive up to a 4 axis CNC machine. It has inputs for minimum and maximum limit switches, emergency stop, spindle control, Z-probe and auxiliry outputs to control a dust collection system or other auxiliry systems.
