Candle 1.1.7 is a free, open-source G-code sender and CNC machine controller designed specifically for GRBL-based firmware. It is widely used by hobbyists for 3018-style desktop CNC routers to visualize toolpaths and manage cutting operations. 🛠️ Step 1: Download & Initial Setup

Candle is "portable" software, meaning it does not require a traditional installation process.

Download Version 1.1.7: Visit the Official GitHub Releases to download the .zip file. Expected output: Candle version: 1

Extract Files: You must extract the contents of the zip file to a folder on your computer (e.g., your Desktop or C:\Candle). Running the application directly from the zip will cause errors.

Install Drivers: Your computer needs to recognize the CNC board. Most machines use the CH341SER driver.

After installing, check Device Manager to find your machine's COM Port (e.g., COM3). ⚙️ Step 2: Configuration

Before your first cut, you must link the software to your machine.

Launch Candle: Open the extracted folder and run Candle.exe. Select Port: Go to Service > Settings. Connection: Set Port to the COM number you found earlier. Set Baud Rate to 115200 (standard for GRBL 1.1).

Confirm Status: Look at the bottom-right console. It should say Idle or Alarm rather than "Port Opened". 🚀 Step 3: Running a Project

Open File: Click File > Open and select your .nc or .gcode file.

Jogging: Use the buttons on the right to move the spindle to your starting point on the material.

Set Work Zero: Click Zero XY and Zero Z to tell the machine this is the starting position. Send: Press Send to begin the carving process. ⚠️ Troubleshooting Common Issues

Jog Buttons Not Working: This often happens if you are using Candle 1.1.7 with an older version of GRBL (v0.9). Upgrade your CNC's firmware to GRBL 1.1 or use Candle 1.0.

Missing .dll Errors: If you get an "ig4icd32.dll missing" error, ensure your graphics drivers are up to date, as Candle requires OpenGL 2.0 support.

Spindle Doesn't Move: Ensure the 24V power supply is plugged into the CNC board; USB alone only powers the logic, not the motors. Customizing user buttons for quick commands?
