Arduino-Based Laser Engraver
CNC – Arduino / LaserGRBL
This project was a custom-built laser engraver controlled by an Arduino Uno with a CNC shield and stepper drivers.
The engraver interfaced with a PC running LaserGRBL, which converted images into G-code toolpaths for the Arduino.
The mechanical frame was assembled with custom parts designed in SolidWorks and cut on a waterjet machine, with the full wiring and assembly completed by hand.
The system was capable of engraving wood, leather, plastic, and glass with high precision.
CNC Shield and Wiring
