The Duet 3 Mainboard 6HC is a fully featured, high-power controller for 3d printers, CNC machines, and more. With 6 high current stepper drivers, 4 high current loads, 6 fans, and more IO on board, it can control many machines directly, with the ability to add much more capability through CAN-FD connected expansion boards.
The overall aim of the Duet 3 family is to allow for maximum flexibility of machine design through highly capable main boards, expansion boards, tool boards, and custom expansion modules. This advanced hardware is enabled by our innovative RepRapFirmware 3 firmware running on the Duet 3 Mainboard and optionally DuetSoftwareFramework running on a single board computer.
Powerful 32bit Atmel ATSAME70: ARM Cortex-M7 microcontroller running at up to 300MHz.
CAN-FD BUS for connecting multiple expansion boards and tools.
Dedicated SPI Bus to Single Board Computer (SBC).
6x TMC2160/5160 high-current drivers with the latest Trinamic features.
|High current outputs
1x15A and 3x 5A PWM outputs for heated bed, extruders and similar.
|Medium current outputs
6 PWM controllable outputs for fans or similar. 3 of these support 4 wire fans including tacho reading.
Nine I/O connectors with 3.3V output signal level and 30V-tolerant inputs.
4 thermistor/PT1000 inputs.
Runs RepRapFirmware 3.x – Supports all common machine geometries, easily configurable for your specific machine requirements.
