[$] Open-source CNCing

Last year Sienci Labs finished its Kickstarter campaign for the open-source LongMill Benchtop CNC Router - its second successful open-source CNC machine Kickstarter campaign. CNC routers allow users to mill things (like parts) from raw materials (like a block of aluminum) based on a 3D-model. The LongMill is a significant improvement over the original sold-out Mill One and makes professional-quality machining based entirely on open-source technology a reality. As an owner of a LongMill, I will walk through the various open-source technologies that make this tool a cornerstone of my home workshop.
