Use this tag for questions about 3D printing with the micro-controller hardware platform Arduino. For general Arduino questions, please use the Arduino Stack Exchange site.

A low-cost solution for controlling 3D printers is the open-source Arduino micro-controller hardware platform. Many affordable boards use Arduino family micro-controllers to control the motion, heating, cooling, etcc using the digital and analog input/output (I/O) pins of the micro-processor. Open-source software is available to compile and upload the various flavors of that are available.
