Gcode Tools

A collection of G-code postprocessing tools. Mostly for 3D-Printing.

This software is in an early development stage. Things might break.

General Usage

gct.py [-o FILE_OUT] COMMAND ... FILE_IN

If no FILE_OUT is given, output is written to stdout.

Commands may have command-specific parameters.

Check gct.py -h for more information.

Available Tools

Strip

Removes all comments from a gcode file. This is a minimal parser for development, but may be useful on its own.

Usage

gct.py strip FILE_IN

Gradient Infill

Changes the amount of extrusion depending on the distance to the closest perimeter. This functionality was adapted from GradientInfill by CNC Kitchen. Many thanks to Stefan for his great work!

Usage

gct.py gradient_infill [--flow_min FLOW_MIN] [--flow_max FLOW_MAX]  [--width WIDTH] FILE_IN

Check gct.py gradient_infill -h for more information.

Notes

• Currently gradient_infill probably only works with gcode created by PrusaSlicer.
• Currently only works with infill consisting of small line segments.
• Print Settings -> Output options -> Verbose G-code must be enabled.
• Printer Settings -> General -> Use relative E distances must be enabled.
• On printers with bowden extruder, reduce the speed for the infill.
