I recently got a mini linear servo which I plan to use to pick up and place down a marker for my CNC plotter project. I decided to write up a guide on how I got it all working.

You can see a wiring diagram and code used for both a simple sweep demo and manually controlling the position with a potentiometer: http://ericeastwood.com/blog/12/cnc-...-linear-servos



If you need to control some steppers, I made a thread about it previously.
