This guide will walk you through the installation process for the software that controls your EM-Smart laser engraving machine.
You have two software options for your laser engraving machine: EZCAD and LightBurn.
If you need guidance on installing and setting up LightBurn for your EM-Smart laser, you can refer to this article: LightBurn Installation Guide: Set it up For your Fiber Laser Engraver.

Part 1. How to Install EZCAD Software on a New Computer (No Prior LightBurn Installation)
Note: If you have previously installed LightBurn on this computer, you can directly skip to Part 2
Step 1: Connect the Machine
- Connect your laser engraver to your computer using the video provided in the USB.
- Turn on the EM-Smart laser engraver by pressing the power button (make sure the emergency stop button is disengaged).
Step 2: Install the EZCAD Driver
- Open your computer's Device Manager.
- Click the "Refresh" button (indicated by a red arrow in the image below) to connect the driver.
- Once the driver is connected, you should see "BJJCZ Device" listed in the Device Manager.
- If the driver doesn't appear, try restarting the laser engraver or clicking the "Refresh" button again

Step 3: Open EZCAD Software
Copy the entire folder from the USB drive to your computer's desktop.
Open the EZCAD software (indicated in the image below).
For easy access, you can create a shortcut to EZCAD on your desktop. This will help you quickly find the software next time you need it.

Step 4: Find the Focus
Click on an empty area of the software (don't import any files or content yet).
Click "Red" (ignore the pop-up window and don't close it).


Now you can write any text or draw any pattern or import your vector image and start engraving!
That's it! You've successfully installed EZCAD software, and you can start engraving using your EM-Smart laser engraver.
Important:
- We have already imported the calibration parameters into the EZCAD software on your USB drive, so you don't need the .cor calibration file. You can start using the software right away.
Part 2: How to Install EZCAD on Computers with Previous LightBurn Installation
