This board controls all of the functions of the extruder. Features of this controller include: monitoring the temperature of the hot end, heating the hot end, providing current to a heated table, fan control, and communicates to and from the 3D Printer main board and Arduino Mega pair.

This stepping motor driver plugs conveniently into the 3D Printer main board. No cables from the main board to this board is necessary.

This board plugs into the Arduino Mega 2560 and provides connections to the stepping motor drivers, end stops, RS-485, a ribbon connector for other functions, and a simple 12 volt terminal.

This board becomes the brain of the 3D Printer and serves as the main interface to the computer. This high end Arduino product can be used for many applications.
