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 feature description is available on our documentation; in summary:
Powerful 32 Bit Processor.
Dedicated ethernet module.
Super quiet TMC2224 stepper drivers, up to 256 microstepping.
High speed SD card and support for a second SD external card if required.
Three heater channels for a heated bed and two extruder heaters.
Support for Thermistors and PT1000 sensors wired direct to the Maestro, along with Duet3D PT100 and Thermocouple daughterboards.
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.
