MKS SERVO42C Closed-Loop Stepper Driver Board

⚙️ Silent, High-Speed, No Step Loss

Overview

The MKS SERVO42C V1.0 is a position/speed/torque closed-loop stepper motor driver board, built for 3D printers and CNC projects requiring smooth, silent, high-speed motion without step loss. Field-Oriented Control keeps noise, vibration and heat to a minimum.

Key Features🔄 Closed-Loop Control

Position/speed/torque closed-loop operation runs at high speed without losing steps.

🔇 Low Noise Operation

Field-Oriented Control delivers low noise, low vibration and low heat generation.

🎯 14-Bit Magnetic Encoder

High angle resolution of 0.08 degrees for precise motion control.

⚡ Flexible Subdivision

Supports 1-256 microstepping, including odd subdivisions like 11.
