Setting up LightBurn for a fiber laser engraver like the EM-Smart allows you to achieve precise, professional engravings with ease.
In this guide, you’ll learn the complete LightBurn setup for fiber lasers—from download and installation to the optimal LightBurn fiber laser engraver settings. Following these steps will ensure that your LightBurn fiber laser setup is ready for high-quality engraving projects, allowing you to unlock the full potential of your EM-Smart laser with ease.
If you need guidance on installing and setting up EZCAD for your EM-Smart laser, you can refer to this article: EZCAD Software Installation Guide (2024): A Step-by-Step Tutorial.
Let’s get started by preparing your machine for the setup.
Start by powering on your EM-Smart fiber laser engraver and connecting it to your computer. Be sure the emergency stop button is disengaged and that the machine’s power switch is on.
After downloading, proceed to install LightBurn and import your machine’s calibration file, which is crucial for accurate engravings.
Choose JCZFiber as your device type. Follow the prompts to select the "markcfg7" file, located in the EZCAD folder on your USB drive. This calibration file includes essential settings like calibration parameters and port information, ensuring that your machine is correctly set up with LightBurn.





Correct focusing is vital for precision in laser engraving. LightBurn helps you find the focal point using two red alignment dots on the work surface.
To ensure everything is working smoothly, run a quick test project in LightBurn. This will help verify that your connection, settings, and calibration are all correct.
Following these refined steps, your LightBurn software and EM-Smart fiber laser engraver will be ready for precise, high-quality engraving projects. With this optimized setup, you’re equipped to create detailed designs and achieve professional results.
LightBurn is compatible with most fiber laser engravers, including brands like EM-Smart. However, it’s always best to verify compatibility by checking the device list on the LightBurn website or by consulting your laser’s manual. EM-Smart lasers, for instance, are fully compatible, making setup and operation straightforward.
Yes, to fully unlock all features in LightBurn, you’ll need a license key after the 30-day trial period. This license grants you access to advanced tools, ongoing updates, and customer support, ensuring you get the most out of your EM-Smart fiber laser engraver.
You can conveniently purchase the LightBurn license key directly from the EM-Smart website at an affordable price, tailored specifically for EM-Smart users. This ensures compatibility and gives you peace of mind as you continue creating with your LightBurn software and your galvo laser engraver.
If you experience connection issues between LightBurn and your EM-Smart laser, try uninstalling and reinstalling the LightBurn software. This can often resolve communication problems. Additionally, ensure that the USB connection is secure and that the necessary drivers are correctly installed.
This is simple! All necessary calibration parameters for your EM-Smart laser are already stored in the "markcfg7" file, which is included in the EZCAD folder on your USB drive. Importing this file into LightBurn will automatically load the essential settings, allowing for a smooth setup without extra .cor calibration files. (Detailed steps shown in Step 2 above.)

The ideal settings in LightBurn—such as speed, power, frequency, and passes—can vary depending on the material you’re engraving.
For best results, refer to the manufacturer’s marking parameters for your EM-Smart fiber laser or perform a settings test, as shown in the video below.
Running an output settings metrics test helps fine-tune the laser’s performance and ensures optimal results across various materials.
Inconsistent results can stem from improper focus, incorrect settings, or calibration issues. Ensure that your focus is precisely set (using the two-dot method), and check that you’ve chosen the right power and speed for your material. Regularly cleaning the laser lens and maintaining your machine can also help prevent inconsistency.
For laser or red light issues, double-check that your port settings are configured correctly.
Refer to the provided image (note the data circled in red) for guidance on the correct port settings. Be sure to select "IPG_YLP" for standard machines, such as EM-Smart Basic, One, while MOPA models should use "IPG_YLPM" to ensure proper functionality.
