Duet 3 Main Board 6XD v1.02

An advanced, high power controller that features support for 6 external stepper motor drivers, along with similar outputs and IO as the Duet 3 Mainboard 6HC. The Duet 3 Main Board 6XD is a fully featured, high powered controller aimed at machines which require external steppers or servos. This board has support for 6 external stepper/servo motor drivers, along with similar outputs and IO as the Duet 3 Mainboard 6HC. In addition some of the IO is provided as opto-isolated signals to ease integration with PLCs and other industrial control systems. The overall aim with the Duet 3 family is to allow for maximum flexibility of machine design through highly capable main boards, expansion boards, tool boards and custom expansion modules. This advanced hardware is enabled by our innovative RepRapFirmware 3 firmware running on the Duet 3 Mainboard and optionally DuetSoftwareFramework running on a single board computer.

FEATURES	SPECIFICATIONS
