UC300 MACH3 USB 6-Axis CNC Controller

UC300 Mach3 USB 6-Axis CNC Motion Controller – Product Data

Overview

The UC300 6-Axis is a high-performance external motion controller designed for Mach3 CNC software. Unlike standard 4-axis models, this version supports up to 6 axes (X, Y, Z, A, B, C), making it ideal for advanced CNC machines requiring multi-axis synchronization. It communicates via USB, removing the need for a parallel port and delivering smooth, precise, and stable motion control for both stepper and servo systems.

Key Features

• Axis Support: Controls 3 to 6 axes (X, Y, Z, A, B, C)
• Pulse Output: Up to 300 kHz per axis for high-precision motion
• USB Communication: Stable, real-time communication with Mach3 via USB
• Motor Compatibility: Works with stepper and servo motors using pulse/direction signals
• Digital Inputs: 16 opto-isolated digital input ports (varies slightly by PCB revision; most 6-axis models provide more inputs than the 4-axis version)
• Digital Outputs: 12 opto-isolated digital output ports for relays, coolant, spindle control, etc.
• Analog Output: One 0–10V analog output for VFD spindle speed control (PWM configurable)
• Power Supply: Operates on 24V DC, minimum recommended current 1A
• Motion Control Chip: ARM-based motion controller ensures stable and reliable performance
• MPG Support: Compatible with standard MPG handwheels and DigitalDream MPGs
• Extended I/O: Additional pins made possible due to expanded 6-axis architecture
