4-Axis CNC Breakout Board Controller 100Khz USB Control for Mach3

The device features a driver-free design, powered and controlled via the ST-USB-C USB cable, and is compatible with all versions of Mach3 software and Windows systems. The ST-V3 supports up to 4-axis synchronous motion control and can regulate spindle motors via PWM signals, making it suitable for small CNC machines such as engravers.
Additionally, the ST-V3 is equipped with four signal input ports and four signal output ports, enabling various functions including emergency stop, homing, and automatic tool setting. It also includes a handwheel interface for convenient manual adjustment and control during operation.

Features

• Equipped with ferrite-beaded USB cable to reduce EMI
• Automatic tool setting for quick workpiece calibration
• 4 opto-isolated relay outputs for robust signal handling
• Emergency stop input and limit switch support for safety
• Flexible spindle control: Supports PWM mode and relay mode
• Handwheel interface for manual jogging and precision adjustment
• 4 opto-isolated digital signal inputs (expandable to 12 inputs via configuration)
• Supports up to 4-axis linkage control. The 4th axis can be set as a follower axis
• Automatic homing (return-to-zero) with follower axis auto-leveling during the process
• Industrial-grade anti-interference design with imported components for high reliability
• High-precision interpolation with a 100KHz output pulse frequency, minimizing machining errors
• Dual terminal options: Screw-type terminals and 2.54mm pitch pin-header terminals for wiring flexibility
• USB interface for universal compatibility—works with any computer running Mach3(requires only a USB port)
• Driver-free design for seamless integration with diverse hardware/software environments(supports various Windows versions, including WinXP and Win7.)
