Automated CNC Machine Using Arduino | Final Year Projects in Lahore Pakistan
How to Make an Automated CNC Machine Using Arduino
Creating an Automated CNC Machine using Arduino is one of the best engineering projects for students in Lahore, Pakistan. Whether you are searching for final year projects near Hall Road Electronics Market or a DIY automation project, this guide explains every detail—from circuit design to component setup.
By learning how to make and how to use a CNC machine controlled by Arduino, you’ll master the basics of automation, electronics engineering, and IoT applications.
Understanding CNC Automation
A CNC (Computer Numerical Control) machine automates cutting, drilling, or milling tasks using programmed commands. With Arduino-based control, it becomes cost-effective and accessible for students projects and industrial prototypes.
This project is designed for mechanical, electrical, and electronics engineers looking for practical automation solutions.
Main Components Required
Building an Automated CNC Machine needs affordable electronics parts, all easily available in Lahore’s Hall Road electronics market or at QKZee Technologies (QKZ Tech).
| Component | Purpose |
|---|---|
| Arduino UNO / Mega | Main controller for CNC operation |
| A4988 or DRV8825 Drivers | Stepper motor control |
| NEMA17 Stepper Motors | Precision motion control |
| 12V Power Supply | Powers motors and control board |
| CNC Shield V3 | Interface for Arduino and drivers |
| Limit Switches | Detects motion limits for safety |
| Frame and Lead Screws | Provides movement stability |
| Software – GRBL & Universal G-code Sender | For machine control and programming |
How to Make the Circuit Connections
1. Power Setup
Connect the 12V power supply to the CNC Shield and Arduino board. Ensure proper grounding to prevent voltage spikes.
2. Motor and Driver Setup
Insert the A4988 or DRV8825 drivers into the shield slots. Connect stepper motors (X, Y, and Z axes) to respective motor ports.
3. Limit Switch Wiring
Attach limit switches at both ends of each axis. These prevent the machine from exceeding its motion limits.
4. USB Communication
Connect Arduino to your computer via USB. This allows communication through GRBL firmware for G-code control.
Programming the Arduino with GRBL
The GRBL firmware is an open-source software that converts G-code commands into motion control.
Download GRBL library in the Arduino IDE.
Upload it to your Arduino UNO.
Open Universal G-code Sender (UGS) software.
Load your CNC design file and run commands to control movement.
This setup enables smooth, accurate automation for cutting, engraving, and milling tasks.
How the CNC Machine Works
When you load a design into the software, the G-code is sent to Arduino.
The CNC Shield interprets commands and moves the motors accordingly.
Each motor turns the lead screw, shifting the tool head precisely.
Limit switches ensure the tool stops safely at the defined boundary.
The process achieves accurate mechanical automation ideal for engineering projects, industrial models, and DIY robotics systems.
