Description
The MKS SERVO42A V1.1 is an innovative conversion kit from MakerBase that transforms a standard NEMA 17 (42x42mm) stepper motor into a high-precision closed-loop servo system. By integrating a positional sensor, the module continuously monitors the motor’s shaft position, making real-time adjustments to ensure the output steps perfectly match your input commands. This effectively eliminates missed steps and positional errors, even during high-speed operations.
Engineered for seamless integration, this closed-loop system allows you to significantly boost your 3D printer’s performance—enabling speeds of up to 200mm/s without requiring complex firmware modifications or major hardware overhauls. It is an ideal upgrade for 3D printers, CNC routers, and precision slide tables that demand both the high torque of a stepper motor and the accuracy of a servo.
Key Features
- Closed-Loop Accuracy: On-the-fly position correction ensures no missed steps, even under heavy loads or high-speed maneuvers.
- Plug-and-Play Performance: Fully assembled and pre-debugged for immediate, easy installation.
- Performance Boost: Enables higher print speeds (up to 200mm/s) without compromising print quality.
- Advanced Configuration: Fully configurable via serial port debugging; supports multiple PID adjustment methods (sPID, pPID, vPID).
- Versatile Connectivity: Includes an integrated USB interface, serial port, and a dedicated OLED display header for advanced monitoring.
Package Includes
- 1 x MakerBase MKS Closed Loop NEMA 17 SERVO42 Motor with Adapter V1.1 (Display not included)
