Exploring Creative applications in the Digital Age: A review of Computer Numerical Controlled Plotter

Computer Numerical Controlled (CNC) plotters have a wide range of applications, including computer-aided drawing, architectural drawing, and printed circuit board printing. These applications can also be extended to serve person with disabilities class by printing signatures and stamps. CNC plotters are developed for diverse uses. However, cost-effectiveness remains a priority. This review examines different CNC plotters designed for various applications, investigating input data types, generating and streaming geometric code (G-code) methods, and communication modes with microcontrollers. Open-source and custom-built software is commonly used for G-code generation, streaming, and parsing. They are fast and contribute to cost reduction. However, a significant drawback is the reliance on a personal computer to run this software. Additionally, the plotting process can become cumbersome and time-consuming when the input data needs frequent modifications. In order to overcome these challenges, implementing a suitable streaming protocol between a transmitting microcontroller setup and a receiving microcontroller that is interfaced with a secure digital (SD) card module could potentially eliminate the need for streaming software. Similarly, generating polar geometric coordinates for simple shapes like circles, straight lines, inclined lines, and arcs based on user-provided parameters can reduce the dependency on G-code generation software. This approach not only saves time but also maintains cost-effectiveness.
