Building a 3D Printer: Motors and Controls

3D printers require a reliable and robust control system to provide the proper quality of printed parts. The goal of this project was to design and implement the electronic and software controls for the large scale 3D printer. This system must be able to run all three print heads as well as color mixing in the central diamond print head. The resulting design for the control system utilized a RUMBA control board running with Repetier-Firmware as the printer firmware. A separate system was designed for the heat beds, which used an Arduino Uno to control a set of relays to maintain the set temperature to the heat beds
