In this project, I created a custom 3- a xis CNC machine prototype designed specifically for the precise cutting of jewelry and precious stones like diamonds. The machine was built to achieve high accuracy, capable of cutting intricate designs into materials such as stone and metal. To reduce costs, I replaced the original expensive control system with a custom one, using 28 BYJ stepper motors and a CNC shield to control the X, Y, and Z axes. The system also features an HTTP web server running on a Wemos D 1 microcontroller, enabling remote control through a web dashboard and joystick. This solution was not only cost- e ffective and easy to repair but also provides the client with a reliable and high- precision tool for crafting jewelry and stone pieces.
