STL to G-code Converter

An STL to G-code converter is a software tool that translates 3D model data (STL format) into machine instructions (G-code) for CNC machines and 3D printers. It essentially automates the Computer-Aided Manufacturing (CAM) process, preparing your 3D design for physical production by defining the toolpaths and movements the machine will follow.

Converting an STL file to G-code using this tool is straightforward:

1. Upload or Drag-Drop: Begin by uploading your STL file using the designated area or by simply dragging and dropping it into the application.
2. Configure Machining Parameters: Adjust settings such as safe Z height and cut depth per pass according to your project's requirements.
3. Set Tool Specifications: Define your tool's diameter, stepover percentage, spindle speed (RPM), feed rate, and plunge rate.
4. Generate G-code: Click the "Generate G-code" button to process your file with the chosen parameters.
5. 3D Visualization: Review the generated toolpath in the interactive 3D viewer to ensure it meets your expectations.
6. Download or Copy: Finally, you can either copy the generated G-code to your clipboard or download it as a .gcode file for use with your machine.

Yes, this STL to G-code converter is completely free to use. There are no hidden costs, subscriptions, or registration required. All processing is done client-side within your browser, ensuring your privacy and providing instant results without consuming server resources.

Currently, our online tool exclusively supports the STL (Standard Triangle Language) file format for 3D model input. This includes both ASCII and binary variations of STL files, which are widely recognized as the standard for 3D printing and CNC machining workflows.

Absolutely! The tool provides full control over various machining parameters, allowing you to fine-tune the G-code output precisely:

• Safe Z Height (mm)
• Cut Depth per Pass (mm)
• Tool Diameter (mm)
• Stepover Percentage (%)
• Spindle Speed (RPM)
• Feed Rate (mm/min)
• Plunge Rate (mm/min)

All these parameters can be adjusted in real-time before G-code generation, giving you flexibility for different materials and machine capabilities.

The G-code output is generated using professional algorithms designed for precision, making it suitable for both CNC machining and 3D printing applications. While the tool aims for high accuracy, the ultimate quality and precision of the final product will also depend on the resolution and accuracy of your initial STL file, as well as the calibration and capabilities of your specific CNC machine or 3D printer. Always perform a verification pass or simulation if available on your machine.

Yes, once the web application has fully loaded in your browser, all subsequent file processing and G-code generation occur entirely client-side. This means you do not need an active internet connection to convert your STL files once the page is loaded. No data is uploaded to external servers, ensuring your work remains private and uninterrupted even without connectivity.

The generated G-code adheres to standard G-code specifications, making it broadly compatible with most CNC mills, routers, and 3D printers that accept G-code input. This includes popular firmwares and controllers like Grbl, Marlin, and others. However, it's always recommended to consult your machine's documentation for specific G-code dialect compatibility, and perform a test run with simple files first.
