Re: [CAD_CAM_EDM_DRO] Re: Question tuning G320 servoamps.

G320's are sink only and must have +5v on the common to work. I have been
told that running the voltage backwards through an IR LED (their optos) is
not good for them so you do not want to connect the common (+5) to ground
instead. The G340 is the one that is switchable.
