Fast G-code frame bounding box generator and framing G-code generator in pure C, designed for CNC, laser, and 3D printer files. This library is optimized for speed and efficiency, making it ideal for processing large files quickly.

Note: Only X and Y coordinates are considered for bounding boxes, as Z coordinates are not considered in the bounding box calculations.

• Pure C implementation - 26x faster than Python
• Zero runtime dependencies - only Python standard library
• Universal compatibility - handles CNC (.nc), laser (.gcode), 3D printer files
• Professional grade - processes 500MB+ files in seconds
• Cross-platform - Windows, macOS, Linux with automatic compilation

git clone https://github.com/offerrall/gcode-bounds
cd gcode-bounds
pip install .

from gcode_bounds import get_bounding_box, generate_framing_gcode

# Get bounding box
bounds = get_bounding_box("part.nc")

# Generate frame
gcode = generate_framing_gcode(*bounds, power=15, speed=1500)

# Save
with open("frame.gcode", "w") as f:
    f.write("\n".join(gcode))

• CNC files (.nc)
• Laser files (.gcode)
• 3D printer files (.gcode)

• Python 3.8+
• C compiler (auto-detected)

Windows: Install Visual Studio Build Tools
Linux: sudo apt install build-essential python3-dev
