Overview

In this Project, “Arduino Based CNC Machine” we will design our own CNC Machine using Arduino. Along with that we see the complete working of CNC Machine.

Introduction

An Arduino-based CNC (Computer Numerical Control) machine is a versatile and cost-effective solution for automating precision tasks like milling, 3D printing, laser cutting, engraving, and more. Arduino, a popular open-source micro controller platform, serves as the brain of the CNC machine, enabling it to interpret computer-generated instructions (usually in the form of G-code) and precisely control the movement of motors and tools.

Basic Workflow of an Arduino-based CNC Machine

Design: Create a digital design or model of the object you want to produce using CAD (Computer-Aided Design) software.

G-code Generation: Convert the CAD design into G-code, which is a series of commands that specify the tool's movements, speeds, and other parameters. Specialized software or slicers (e.g., for 3D printing) generate this G-code.

Arduino Programming: Write or upload firmware (e.g., Grbl, Marlin) to the Arduino that can interpret G-code commands and control the stepper motors and other machine components.

Assembly: Build the physical structure of the CNC machine, including mounting the motors, tool head, and any additional components.

Electrical Wiring: Connect the Arduino, stepper motors, motor drivers, limit switches, and power supplies, ensuring proper grounding and safety measures.

Calibration: Calibrate the machine by setting parameters such as steps per millimeter, acceleration, and maximum speed for each axis.

Software Setup: Install CNC control software on your computer and configure it to communicate with the Arduino. This software allows you to send G-code commands to the CNC machine.

Operation: Load your G-code file into the CNC control software and start the machine. The Arduino interprets the G-code commands, and the motors move the toolhead accordingly to create the desired object.
