 # MicroManipulatorStepper
 A sub-micrometer 3D motion control plattform.
+
+This project contains an open source low-cost, easy-to-build motorized **XYZ Micro-Manipulator** motion controll platform achieving sub micrometer precision.
+It's designed for applications such as optical alignment, probing electronic components, and microscopy.
+Thanks to its parallel kinematic structure and miniature ball joints, it achieves good mechanical stiffness and a large range of motion.
+The motors are off the shelf stepper motors driven by a 30kHz closed loop controller and a very precise PWM signal.
+A 'magnetic gearing' approach increases the resolution of the low-cost megnetic rotary encoders by a factor of 30 allowing for steps down to 50nm.
+
+The device can be controlled via simple G-Code commands over an USB serial interface and is thus easily integrated into other projects.
+The firmware implements a complete motion planning stack with look-ahead for smooth and accurate path following capabilities.
