Developing Low Cost and Smart Laser-based Paper Cutter based on Open Source 3D Printer

For satifying the needs of the maker movement, the cheap tools like low cost 3D printers are needed and their functions are required to be upgraded frequently. Especially, the intelligent functions, like auto-bed-leveling and auto-fan-cooling, dramatically transform current printers to high quality and easy-to-use printers. In order to develop more useful tools to support makers, this paper introudces the smart Laser cutter which was redesigned from the Prusa i3. It is capable to detect the level status of cut bed to keep its cut works exactly at focal length.
