DIY CNC/LASER ENGRAVER

Build Your Own CNC Machine or Laser Engraver at Home with Arduino! You can create a 3D printer, laser engraver, or CNC machine for home projects using an Arduino and pairs of stepper motors. The old CD/DVD drive provides the stepper motors, while mini servo 9g helps build this project. You can upgrade with NEMA stepper motor and high torque servo motor. Arduino controls the stepper motors for axial movement, Inkscape generates G-code for images/text, and Processing executes the G-code and commands through Arduino interface to achieve directional and positional movements per geometry defined in the G-code. G-code involves geometrical codes that help the machine move axially to reach a specific point using stepper motors, while M-code switches on/off features like spindle/laser light or extra attachments. Inkscape is a free and open-source vector graphics editor for creating illustrations, diagrams, and more. Arduino is an open-source hardware and software company that designs single-board microcontrollers for digital devices. The Arduino code for CNC machine axial control can be uploaded to the board of your choice (UNO/MEGA/NANO). Make a two-axial CNC machine with stepper motors connected to X and Y axes, while a servo controls the Z axis for pen or laser up/down. Connect them according to the circuit diagram and edit the "arduino_CNC.ino" file if needed. Burn the "arduino_CNC.ino" under the "CNC ARDUINO CODES" folder, open Processing, feed the "GCODE_PROCESSING_SOURCE_CODE," and follow commands.
