UC300 MACH3 USB 6-Axis CNC Controller

6-Axis USB Motion Controller Board (UC300-6 Axis)

Product Description

The UC300 6-Axis USB Motion Controller by Digital Dream is a high-spec external CNC motion control solution designed for complex multi-axis machinery operating on Mach3 software. Featuring high-speed USB connectivity, it drives up to 6 full axes (X, Y, Z, A, B, C) with individual pulse and direction signals up to 300 kHz per axis. Equipped with robust dual-power isolation, VFD analog speed output, 12 inputs, 10 outputs, and full MPG/pendant support, the UC300-6 Axis offers high reliability for 5/6-axis machining centers, dual-gantry setups, and advanced automation.

Key Features

• Full 6-Axis Simultaneous Control: Drives up to 6 axes (X, Y, Z, A, B, C) simultaneously for complex multi-axis CNC setups.
• 300 kHz High Stepping Frequency: Delivers high-frequency step outputs (up to 300 kHz/axis) for high-resolution stepper and servo motor systems.
• Industrial Opto-Isolation: Photoelectric isolation between host PC communication and motor/IO control sectors prevents ground loop noise and interference.
• Integrated Spindle Speed Control: 0–10V VFD speed control output (PWM configurable) along with spindle speed feedback (INDEX) input.
• Comprehensive I/O Setup: 12 opto-isolated digital inputs and 10 opto-isolated outputs (DB9 connector with built-in relay driver IC).
• Selectable MPG Handwheel Modes: Onboard hardware switch allows instant compatibility with Standard MPGs or Digital Dream NVMPG handwheels.
• Potentiometer Override Interface: Hardware terminals for direct adjustment of Feed Rate Override (FRO), Spindle Speed Override (SRO), and Jogging Rate (SJR).
• Serial Extension Port (UART): Allows future expansions such as external HMI modules or extra IO boards.
