Open MicroManipulator – A sub-micrometer 3D motion control plattform

A GitHub user named 0x23 has open-sourced a sub-micrometer 3D motion control platform called the Open MicroManipulator. The platform is based on a 3D printed frame and uses a combination of stepper motors and a Raspberry Pi to achieve precise control. The user claims to have achieved a positioning accuracy of 0.1 micrometers and a velocity of 5 mm/s. The project is described as being in its early stages and is seeking community feedback and contributions.
