CNC 2D Plotter is a project designed to draw a specific diagram on paper by giving the commands from the computer. It uses a software called Inkscape which allows us to draw vector graphics on the computer and then generates a G-code. The axes is controlled by two stepper motors, one which controls the movement along y-direction which moves the central limb. The second stepper controlled the movement along x-direction by moving the pen holding plate. The pen movement for drawing is controlled by the servo motor in the up-down direction. It is controlled by a GRBL controller. GRLB is the open source firmware freely available for every one and is used as a firmware for the CNC machine. GRBL shield and GRBL firmware is best for 3 axis stepper CNC machine. The CNC shield is placed over the Arduino board.
The project uses 3D printed PLA parts and GT2 pulleys and belts.
Working of the Project :
Step1 : Uploading MIGRBL library code to Arduino Uno
Step2 : Connecting Servo motor to GRBL CNC shield.
Step3 : Generating G-code using Inkscape.
Step4: Running the code from controller.
