- WorkBee Replacement Wifi External Antenna Duet 2 Controller is a powerful standalone motion control board designed specifically for the WorkBee CNC Machine. It provides everything needed for reliable, precise motion control in a single package without requiring additional expansion boards or SBC connectivity. The board includes 5 integrated stepper drivers, high-current outputs, PWM outputs, and a range of I/O options. With Ethernet networking built in, it can be easily accessed and controlled from a computer or local network without requiring additional hardware. It comes pre-formatted and pre-loaded with the correct configuration folders and files for the WorkBee Z1 , running our latest WorkBee firmware (3.3). Once installed, you simply need to select your machine size in WorkBee Control to get started. This replacement controller is ideal for restoring full functionality to your WorkBee CNC Machine and keeping it running at peak performance. Key Features Powerful Processing: ARM Cortex-M4F microcontroller for fast, reliable performance. Network Connectivity: Ethernet interface for reliable communication and control. High-Performance Drivers: 5x TMC2660 stepper drivers with advanced motion control features. Comprehensive I/O: Multiple PWM outputs and configurable I/O pins for wide application use. Proven Reliability: A well-established controller ideal for basic multi-axis systems. RepRapFirmware RepRapFirmware is a powerful and flexible firmware designed to run on 32-bit ARM controllers. Configuration is handled entirely through human-readable G-code files stored on the SD card, no recompilation required. The firmware supports hundreds of G-code commands, detailed here: https://docs.duet3d.com/User_manual/Reference/Gcodes Key capabilities include: An object model of machine configuration and state, enabling dynamic access to a wide variety of values. Conditional and looping G-code for advanced automation. Compatibility with all common kinematics, plus the ability to define custom kinematics. RepRapFirmware is paired with Duet Web Control (DWC), a full-featured, browser-based interface for configuration and machine management. DWC adapts to your machine setup, providing intuitive access to controls, monitoring, and job management. Users can also extend functionality with custom third-party plugins, making it easy to tailor the interface to specific requirements.
