MicroManipulatorStepper enables submicron precision 3D motion control using a low-cost, easy-to-build platform. It addresses the need for affordable high-resolution motion control in applications like optical alignment and microscopy. The system utilizes off-the-shelf stepper motors, a 30 kHz closed-loop controller, and a magnetic gearing approach to achieve resolutions down to 50nm.
Notable for its low cost and open-source design, the MicroManipulatorStepper achieves submicron resolution using a unique magnetic gearing mechanism. It offers a flexible G-code interface, a Python API for easy integration, and a complete motion planning stack. A new hardware version (4.0) improves stability and mechanical design.
- G-Code Control: Simple G-code commands for easy integration with existing automation systems.
- Python API: A lightweight Python API for convenient control and data acquisition.
- Open-Source Design: Fully open-source hardware and software for customization and modification.
- Motion Planning: Integrated motion planning stack for smooth and accurate path following.
- Firmware Updates: Regular firmware updates with bug fixes, new features, and improved calibration.
- CAD Models: FreeCAD models available for easy modification and 3D printing.
- Tooling Support: Support for external tools via GPIO pins for applications like laser engraving.
