Low Voltage Electronics - TechforTrade/Thunderhead-Filament-Extruder GitHub Wiki
The extruder is controlled using an Arduino Mega 2560. The Thunderboard shield is used to create an interface between the Arduino and the rest of the machine. You or a PCB manufacturer (contact us in a pinch) will need to make the Thunderboard. Learn more about the Thunderboard on its documentation page. Note The low voltage and mains voltage components have recently been separated to reduce noise especially in the LCD and Keypad. The new enclosure has yet to be designed.
