Duet 3 Main Board 6HC

An advanced, high power controller that features 6x 6.3A stepper drivers, 4 high current heaters, 6 fans and more

Product description

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 Duet 3 family allows 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.


Processor Powerful 32bit Atmel ATSAME70: 32 bit, ARM Cortex-M7 microcontroller running at up to 300MHz
Expansion CAN-FD BUS for connecting multiple expansion boards and tools
Connectivity Dedicated SPI Bus to Single Board Computer (SBC), or, alternatively, connect over an Ethernet network. Wifi via optional Duet 3 WiFi Module (Mainboard 6HC v1.02 or later only)
Stepper Drivers 6x TMC2160/5160 high-current drivers with the latest Trinamic features. Maximum motor current 6.3A peak per phase (4.45A RMS)
High current outputs 1x15A and 3x 6A PWM outputs for heated bed, extruders and similar
Medium current outputs 6xPWM controllable outputs for fans or similar. 3 of these support 4 wire fans including tacho reading
IO Nine I/O connectors with 3.3V output signal level and 30V-tolerant inputs
Temperature Measurement 4 thermistor/PT1000 inputs. Support for two temperature daughterboards for up to 4 PT100 or thermocouple sensors
Supply Voltage 12-48V
Firmware Runs RepRapFirmware 3.x – Supports all common machine geometries, easily configurable for your specific machine requirements
