# Micro Manipulator Stepper (Page under construction)
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.

### ⚙ CAD-Files
All CAD models are made in FreeCAD, to allow everyone to view and modify the design without subscribing or paying for a propriatary CAD solution.
Note that most components are already disgned with the goal to make them easily machinable on a 3-Axis CNC-Mill.
You can also 3D-Print the parts but have to live with thermal drift (carbon filled filaments cam reduce this problem).

Please note that FreeCAD version **1.1.0dev** was used and the files might not work with older versions.
### ⚙ Electronics
The electronics is designed in **KiCAD** and only commonly available modules (Motordrivers, MCU board) are used and connected by a simple PCB. No SMD soldering is required to populate the board to make the build extra accassible.
