Re: [CAD_CAM_EDM_DRO] help for a newbie

Kelly,

I don't think that you will need to connect pins 18-25 to your power supply
ground.

Do check and make sure that you have the 5 volts between pins 18-25 and pin
10 on the Gecko drive. The return for the 5 volts needs to be at the same
ground as the PC.
