Most high-end 2D and 3D fiber laser marking machines come bundled with an official, fully licensed copy of EzCad3 from the factory. The manufacturer handles the activation using the board they installed.
If you need to use EzCad3, there are official, safe, and legal avenues to acquire it:
| Software | Description | Key Features | | :--- | :--- | :--- | | | An open-source command-line tool written in Python by a developer dissatisfied with EZCAD, designed to control JCZ laser controllers. | Command-line interface for engineering applications; cross-platform (Linux, Mac, Windows); works with common laser control boards. | | LaserGRBL | A popular, free, and open-source GUI primarily for diode lasers, but adaptable for many other types. | User-friendly interface; G-code support; advanced settings for speed, power, and parameters. | | LightBurn | A powerful commercial software that offers a free trial. It has added support for many Chinese fiber laser controllers, making it a direct competitor to EZCAD3. | A modern and intuitive UI; supports a wide range of lasers; offers advanced design tools; can be a direct EZCAD replacement for many users. | | Inkscape | A free, open-source vector graphics editor used by many makers to create designs for laser engraving. | A robust set of drawing and editing tools; supports the SVG file format commonly used in laser engraving; requires a separate tool (like LaserGRBL) to send jobs to the laser. | | FreeCAD | A free, open-source parametric 3D CAD modeler that can be adapted for laser engraving workflows. | Powerful CAD tools for creating intricate designs; highly customizable; open-source and free. |
EzCad3 is typically . When you buy a laser machine, the cost of the EzCad3 license is included, and it is usually activated via a physical JCZ control card (e.g., DLC2 series) or a USB dongle.
