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
