The Duet 3 6HC motherboard is a next-generation control board that builds on Duet3D 's experience in developing the most flexible and expandable 3d printer management solutions. It is the core of the Duet 3 family that provides control for a wide range of machines including 3D printers, CNCs, lasers, and more. The overall goal of the Duet 3 series is to allow maximum flexibility in machine design through main boards, expansion boards, toolboards and custom expansion modules. Configuration flexibility and advanced features are provided by the innovative RepRapFirmware 3 running on the Duet 3 main board and the DuetSoftwareFramework running on an external computer (e.g., Raspberry Pi).
Here are the main functions at a glance:
- Powerful 32-bit processor (ARM Cortex M7 @ 300Mhz)
- Dedicated high-speed bus to a single-board computer (e.g., Raspberry Pi) for user interface and plug-ins
- 6 next-generation stepper Trinamic 5160 drivers with speeds up to 4.45 A RMS, 6.3 A peak with firmware control of the entire feature set, including up to 256 microstepping, StallGuard 2 and StealthChop2
- 2 CAN-FD buses supporting the next generation of expansion boards Duet3D, smart tools and custom add-ons. the initial target is support for expansion boards up to 8 x 3 channels (another 24 channels stepper).
- 10 PWM outputs with variable current capability support a high-current heated plate, 3 extruders and 6 fans.
- 9 IO ports for terminals, probes, filament monitors and other sensors.
- 4 thermistor / PT1000 inputs and support for 4 PT100 / thermocouple inputs via optional motherboards.
- Connect via PC, tablet or smartphone on the same network to the built-in web interface.
- Configure the printer and update firmware via the Web interface .
All common 3D printer geometries are supported
Support for a wide range of Z probes including the DC42 IR Z probe and Duet3D Smart Effector for delta printers.
