Description

The Duet 3 Mini 5+ is an advanced 32 bit electronics board for the control of 3D printers and other CNC machines. A full description of all the features can be found in its documentation.

In summary:

• Powerful 32-bit Processor (ARM Cortex M4 @120Mhz).
• Dedicated Ethernet connectivity.
• Connect via PC, tablet or smartphone on the same network to the on board web interface.
• Also setup your printer and update the firmware through the web interface.
• Alternatively there’s a dedicated high-speed bus to a single board computer (such as a Raspberry Pi) for the user interface and plugins.
• Five Trinamic 2209 stepper drivers running at up to 1.4A RMS, 2A peak with firmware control of the full feature set including up to 256 microstepping, StallGuard 2 and StealthChop2.
• CAN-FD bus that supports the next generation of Duet3D expansion boards, smart tools and custom add-ons.
• Seven PWM outputs of varying current capacities support a high current heated bed, two extruder hot ends and four fans.
• Seven IO ports for endstops, probes, filament monitors and other sensors, fully configurable by G Code.
• Three Thermistor/PT1000 inputs and support for two PT100 or thermocouple inputs via the optional daughterboards.
• Provided with Molex compatible plugs and crimps as well as spade connectors for power input, and a micro USB cable.
• Support for a wide range of Z probes including Duet3D’s IR Z probe and the Duet3D Smart Effector for delta printers.
• All common 3D printer and CNC geometries are supported.

The Duet 3 Mini 5+ balances value and performance, and is focused on small and medium sized machines. It provides five on board drivers and the normal complement of heaters, fans, IO, LCD etc. We stock the Ethernet variant, with the option of using an SBC (Single Board Computer, e.g. Raspberry Pi) for control in the same manner as other Duet 3 main-boards. The overall aim with the Duet 3 series is to allow for maximum flexibility of machine design through highly capable main boards, expansion boards, smart tool boards and custom expansion modules. The flexibility of configuration and advanced features are enabled by the innovative RepRapFirmware 3 running on the Duet 3 Mainboard and, optionally, the customised Duet Software Framework running on a single board computer.

The Duet series of 3D printer controllers and the RepRapFirmware they run were instigated and initially designed by us and two other companies; they are now maintained and updated by Duet3D.
