RE: [CAD_CAM_EDM_DRO] Re: Breakout board or cards

And I think it's called a "charge-pump" because when it is on, it is
constantly pumping charge into a capacitor, which stays charged and tells
the rst of the circuit that things are ok. When the pulse train drops out,
no more charge is being pumped into the cap, and it discharges, letting the
rest of the circuit know to shut down.

The chargepump circuit is generally used with the MACH2 CNC
software. When MACH2 is activated, it outputs a unique frequency
which is detected by this circuit. The circuit then activates one of
the output pins. This makes sure that the tool is not able to move
unless MACH2 is activated and in control.
