Re: [CAD_CAM_EDM_DRO] Gecko 5V supply

Terry,

The +5 from the wall wart just goes to the Gecko +5 terminal and the
ground terminal. the +48 motor power is from your home-built linear
power supply; I.E., a transformer, bridge rectifier, and cap. (fuze,
etc). The +5 for the opto-isolator is normally "isolated" from the
motor supply, I'm told. We just didn't want to "steal" it from the PC!
