Design of Low Cost Mini CNC Laser Engraver

Numerous industries employ CNC machines for tasks such as cutting metal, carving wood, and working with acrylic. Even though it is crucial, most engineering institutions are unable to allow students full creative control while using CNC machines due to operating costs and to reduce possible damage to the machine. To decrease complexity, expense, and labor, a low-cost Mini CNC Engraver is proposed. This article describes the design and implementation of a two-dimensional CNC router that can engrave 2D grayscale images or drawings using a high-watt laser module on a surface made of paper, wood, leather, plastic, or foam. Experimental testing is done after building a prototype. Results demonstrate that the system can serve as a cutting and engraving tool for miniature samples.
