Rough Sketch - Limit Switch Diagram for Mach3 USB Board

This is a simple sketch of how the limit switches should be connected to the Mach3 USB board. You will need an additional power supply to power this portion of the board. 24V is not necessary. A 12 volt source coming from a PC power supply or AC adapter should suffice.
