Design and Implementation of CNC Writing Machine Based on Arduino Micro-controller

This paper discussed the design and implementation of a Computer Numerical Control (CNC) machine for writing or sketch by employ parts of computer scraps (DVD-ROM). The Arduino Uno used as the controller for this project with using Inkscape program, which converts images and text into g- code format and then sends this g- code to the processing3 program which is an interface the connection between the arduino and the computer and the language of the CNC machine. The g-code includes a set of x y z coordinates that are sent to the motors, the Z coordinates are transmitted to the servo motor that directs the movement of the pen, the Y coordinates are sent to the stepper motor 1 that directs the horizontal movement of the DVD rail and the X coordinate is send to the Stepper motor 2 that directs the vertical movement of the DVD rail. This project can be used in logo Design. CNC machines can be utilized ceaselessly 24 hours every day, 365 days per year and just should be turned off for intermittent support.
