I recently built a 2D G-Code Viewer that runs entirely in your browser. Just a simple G-Code viewer I wrote in JavaScript mostly for fun.

If you’ve ever looked at raw G-Code, you know how overwhelming it can be. Reading line after line doesn’t really give you a sense of how the tool-path will look. My viewer makes it easy to upload your G-Code and see a 2D top-down path immediately.

Key Features

• Drag and drop your G-Code file into the viewer.
• 2D top-down visualization of the tool-path.
• Lightweight and fast – no slicer or heavy software required.
• Browser-based – use it anywhere without setup.
• Hover over – you can see relevant tool-path info where you need it

Future plans:

None at the moment. if you enjoy it let me know and tell me what you want and ill get around to it.
