Duet 2 Maestro

Duet 2 Maestro

An advanced 32-bit electronic board to power your 3D printers. A dedicated ethernet cable is provided in the box.


The Duet 2 Maestro is an advanced 32-bit electronics board to control 3D printers and other CNC machines. It is in the same product family as the Duet 2 Wifi and Duet 2 Ethernet. It runs the same advanced and flexible RepRapFirmware. The main difference is that the Duet 2 Maestro has lower current stepper motor drivers and less expandability than the Duet 2 Wifi and Ethernet, and it only comes in an Ethernet option.
