Duet 2 Maestro Product Specs (From

  • Powerful 32 Bit Processor: SAM4S8C: 120MHz ARM Cortex-M4 microcontroller, 1024Kb memory, 128Kb RAM and many peripherals.
  • Dedicated Ethernet module: Low level networking is handled by a separate module, this leaves the main processor free to do precise stepper pulse timing and implement other advanced features.
  • Super quiet TMC2224 stepper drivers: SPI controlled and capable of up to 256 microstepping with optional interpolation from any lower microstepping setting to x256.
  • On board High speed SD card and support for a second SD external card if required.
  • 3 heater channels for a heated bed and dual extruders
  • Temp Sensor Support: Four channels capable of thermistor or direct PT1000 support. Add-on daughter board available for PT100 or thermocouple support.
  • 3 PWM controllable and 1 always-on fans. Fans voltage can be selected across two banks from either the input voltage or 5V for added flexibility.
  • Power rating: Each stepper driver is capable of up to 1.6A peak motor current, the bed heater channel is specifically designed for high current (limit to be confirmed by thermal testing).
  • Servo Support: One hobby style servo on the expansion header.
  • Additional Motor Support: Headers for two external stepper drivers with step/direction/enable interface and optional configuration via single wire UART (TMC2208 or TMC2224).
  • Connect via PC, tablet or smartphone on the same network to the Duet Web Control web interface. There is no need for an app install, internet connectivity or cloud service to sign up for yet you can control your printer, upload and start prints from the browser.
  • Setup your printer and update the firmware through the web interface. No need to compile your own firmware.
  • Also connect via USB or serial if desired.
  • Most printers supported: All common 3D printer geometries are supported, with easily modified configuration templates for popular designs. Along with 3D printers a wide variety of CNC machines and laser cutters can be controlled.
  • Firmware support for mixing nozzles
  • Touch Screen support for the PanelDue controller provides a full colour graphic touch screen controller with virtual keyboard. Also talks G-code for maximum flexibility.*
  • It is also compatible with the low cost 12864 LCD .
  • Advanced Calibration Support: Use an optional add-on of DC42’s highly repeatable contactless IR probe combined with advanced firmware features for more accurate printer calibration. Many other probe types are also supported.
  • Power monitoring to allow for state save on power fail.
  • Beta support for the Duet3d Filament Monitor both magnetic and laser versions.

M3D QuadFusion Print Head Specs (From )

Filament Printing Temperature – The Quad 3D Print Head is capable of printing any 1.75mm filament with a printing temp of 255°C or below.

Nozzle – It comes with a 0.35mm nozzle standard, and you can purchase 0.5mm, 0.75mm & 1.0mm nozzles as an add-on.  

Dimensions – 80 x 80 x 85 mm.    

Motor – The Quad 3D Print Head uses four bipolar stepper motors running at a standard current of 525mA at up to 24V.  

Filament Crush Distance Control – The Quad 3D Print Head uses fixed dimension idlers, but allows idler replacement for crush distance adjustment. The default idler configuration is meant to accommodate “rigid” filaments such as PLA and PETG.  

Cooling – The Quad 3D Print Head offers numerous attachment points for motor cooling, cold section and/or part cooling fans. The Quad 3D Print Head includes one cold section/motor cooling fan and two nozzle/part cooling fans.  

Bed Sensing – In addition to their usefulness in attaching cooling fans, the attachment points of the Quad 3D Print Head allow for installation of bed sensors such as IR or inductive probes.
