Duet 3 Expansion Board 1HCL

Duet 3 Expansion Board 1HCL is designed for situations where closed-loop stepper motor control is required in a motion system. Unlike standard stepper drivers, the 1HCL provides position feedback, ensuring the machine knows exactly where the motor is at all times for improved accuracy and reliability.

The 1HCL can also monitor motor temperature, control a motor brake, and handle an endstop input, making it a versatile choice for demanding applications where precision and protection are critical.

They can be daisy-chained together via the CAN-FD bus, this makes it a scalable solution for large automation systems and multi-axis setups.

Key Features

• Powerful Processing: ARM Cortex-M4F microcontroller for fast, reliable performance.
• High-Current Drivers: 1x TMC2160A stepper drivers with advanced motion control features.
• Closed-Loop Control: Provides position feedback for improved accuracy and reliability.
• Motor Monitoring: Supports motor temperature sensing and motor brake control.
• Comprehensive I/O: Multiple PWM outputs and configurable I/O pins for wide application use.

Duet 3 Family

The Duet 3 family is built around a mainboard that acts as the central control unit. Functionality can then be expanded by connecting dedicated expansion boards through the CAN-FD ports, giving the flexibility to add extra stepper drivers, I/O, and specialised features such as closed-loop motor control.

This modular approach makes it possible to scale a system to match the demands of the application. From compact setups to large, complex machines, the Duet 3 Family provides the flexibility to control extensive motion systems for aluminium extrusion setups, CNC machinery, and other advanced motion control applications.
