Coordinate Table Manual Control Unit with DRO

In a few words, this is an arduino based, XY stepper controller witch also works as a Digital Read Out Unit. It displays the X and Y axis coordinates on the LCD, and you can control both axis by pressing the buttons and changing the speed with a 10k linear potentiometer in real time!
