The Duet 2 Maestro is an advanced 32 bit electronics board for the control of 3D printers and other CNC machines. It is in the same product family as the Duet 2 Wifi and Duet 2 Ethernet, and 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. A full description of all the features can be found in our documentation. Summary below.
As of November 15th, 2017, all Duet3D products purchased from Filastruder will be eligible for a 6 month limited warranty. For more information, visit http://www.duet3d.com/warranty.
Note: the Duet 3 Mini 5+ is not yet in production, but is included for comparison
