I have a Raspberry Pi, and Embedded Pi, a motor shield kit v2.0 (Product # 1438) with 2 stepper motors, and the LinkSprite JoyStick Shield v2.4 (mcm part # 83-15168) My intent was to build a table that would slide, in X & Y directions while controlled by the joystick and maybe even save location values on the Raspberry Pi or perhaps the microcontroller itself for recall. The main idea behind this project was to turn a regular sewing machine into a quilting machine by placing it on said table and controlling its movement/travel via the joystick. Also was thinking about rolling the material for 1 of the axis while sliding the table for the other axis.
