Reprap oriented gcode utilities

Project Description

GCodeUtils is a set of utilities to manipulate GCode programs. It is targetting RepRap oriented GCode but isn’t limited to RepRap.

Currently, it is composed of one calibration generation program, a basic gcode modifier (which translates code along X/Y or convert extrusion distance to relative), a stretcher to increase hole size of printed parts and a GCode converter which generate arc opcodes from arc interpolation as segments.


GCodeUtils is installable from PyPI with a single pip command:

pip install gcodeutils

Alternatively, GCodeUtils can be run directly from sources after a git pull:

git clone
cd gcodeutils && python install

or directly from its git repository:

pip install git+

Once GCodeUtils is installed, the .py files located in the cura_plugins subdirectory can be copied into the plugins directory of Cura to be callable from within Cura itself.


Latest documentation can be found online at this address:


GCode parsing is borrowed from GCoder as found in Printrun (
