About the Online GCode Viewer
Welcome to the most advanced and lightweight Online GCode Viewer. Whether you are a 3D printing hobbyist, a professional engineer, or just curious about how 3D printers work, this tool provides a seamless way to visualize your prints before you send them to the machine.
Unlike other tools that are heavy and slow, our viewer is optimized for speed. It runs entirely in your browser using client-side technology, meaning your files never leave your computer. This ensures 100% privacy and security for your proprietary designs.
Key Features
- Instant Visualization: Drag and drop your .gcode files to see the toolpath immediately.
- Cost Estimation: Input your filament cost and diameter to get an accurate price estimate for your print.
- Dual Modes: Switch between a lightweight 2D layer view and a fully immersive 3D simulation.
- Detailed Analysis: Get insights on print time, filament usage (length & weight), and layer count.
How to Use
- Upload File: Click the "Upload GCode" button or simply drag and drop your file into the viewer area.
- Analyze: The tool will automatically parse the file and display statistics in the sidebar.
- Visualize: Use the "2D View" for a quick layer-by-layer inspection or "3D View" to rotate and zoom around your model.
- Check Layers: Use the slider at the bottom to scrub through the printing process from the first layer to the last.
- Estimate Cost: Enter your filament price per kg in the sidebar to see how much the print will cost in materials.
Frequently Asked Questions
What file formats are supported?
We primarily support standard `.gcode` files generated by slicers like Cura, PrusaSlicer, Simplify3D, and Bambu Studio. We also support `.nc` and `.g` files for basic CNC visualization.
Is my data safe?
Absolutely. This tool works entirely on the "client-side". Your GCode file is processed by your browser's JavaScript engine and is never uploaded to any external server.
Why is the 3D view not loading?
The 3D view requires WebGL support. Ensure your browser is up to date and hardware acceleration is enabled. For very large files (>50MB), the 2D view is recommended for better performance.
