Once you are on the Releases page, look for the latest version number, such as 1.1.7 or higher. Under the "Assets" dropdown for that version, you will typically see a file named Candle.zip. Download this folder to your computer. Since Candle is a "portable" application, it does not require a traditional installation process. You simply extract the contents of the ZIP file to a folder on your desktop or C: drive and double-click the Candle.exe file to launch the interface.

Before running the software, ensure your computer has the necessary CH340 drivers installed. These drivers allow your PC to communicate with the CNC controller via USB. Most download packages from GitHub or manufacturer sites will include a folder for drivers, but they can also be found easily through a quick web search if your computer fails to recognize the machine.

After downloading and launching Candle, you will need to configure the settings to match your specific machine. This involves selecting the correct COM port and setting the baud rate, which is typically 115200 for most modern GRBL controllers. With the software downloaded from a trusted source and your settings dialed in, you are ready to load your G-code and start your first carve.

In addition to the official GitHub source, many CNC manufacturers include a version of Candle on the USB drive or CD that comes with the machine. While this is convenient, these versions are often outdated. If you experience connection issues or visual glitches, it is highly recommended to delete the factory version and download the latest update directly from GitHub.

The primary and most reliable source for Candle is the official GitHub repository. GitHub is the hosting platform used by the developer, Denvi, to store the source code and the compiled "ready-to-run" versions. To get the software, you should navigate to the Denvi/Candle repository and look for the "Releases" section on the right-hand side of the page. This section contains the most recent stable builds, usually provided as a ZIP file for Windows users.

Finding the right place to download Candle CNC software is the first step toward bringing your desktop engraving projects to life. Candle, also known as GRBL-Control, is a popular open-source interface designed specifically for GRBL-based CNC machines like the 3018-PRO. Because it is community-driven, the software is free, but you need to ensure you are downloading the official, stable version to avoid bugs or malware.
