All 3D printers require on-board code to translate textual commands (called GCODE) into movement and molten plastic. For this job, most RepRaps (and many commercial 3D printers) rely on Marlin, a compact, adaptable, and streamlined firmware. Marlin's flexibility comes from having a huge number of configurable options. In this article (and accompanying video) I'll be discussing the challenges of building a configurator to help wrangle Marlin's many options, and I'll be showing off some cool Javascript tricks in the process.
