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
