Development of Low-cost plotter for educational purposes using Arduino

With the development of CAD/CAM/CAE concept to product realization time has reduced drastically. Most of the activities such as design, drafting, and visualizations are carried out using high-end computers and commercial software. This has reduced the overall lead-time to market. It is important in the current scenario to equip the students with knowledge of advanced technological developments in order to use them effectively. However, the cost associated with the systems are very high which is not affordable to students. The present work is an attempt to build a low-cost plotter integrating some of the software that are available and components got from scrapped electronic devices. Here the authors are introducing G-code plotter with 3-axis which can implement the given g-code in 2D plane (X-Y). Lifting pen and adjusting to the base component is in the Z-axis. All conventional plotting devices existing until date are costly and need basic knowledge before operating. Our aim is to make students understand the working of plotter and the usage of G-code, achieving this at a much affordable cost. Arduino Uno controls the stepper motors, which can accurately plot the given dimensions.
