No clue how the enable works. They didn't give me any real detailed information, just enough to supposedly get it running, and a baseline of tuning the motors. It's a system from
www.lowcostcncretrofits.com http://www.lowcostcncretrofits.com/servo%20controllers.html 20 amp 3 axis controller and supposedly 1500 oz/in Pacific Scientific servo's. My controller is a little diffrent from the one in the picture, it doesn't have the LED's on the front, but it does have a port for breaking out the 25 pin cable on the back. I'll check the step and direction and see if I get anything.
