svg2gcode

svg2gcode reads an SVG file and produces g-code machining operations from the paths in it.

Supported operations are:

• engraving (follow the path from the SVG)

• offset (follow a path offset inwards or outwards from the SVG path)

• pocket (clear the interior of the path from the SVG)

• drill (in the center of circular paths)

Features:

• ramp or plunge entry moves

• optionally add work-holding tabs

• primitive nesting via duplication on an XY grid

Installation

Clone the svg2gcode repo:

git clone https://github.com/SebKuzminsky/svg2gcode.git
git submodule init
git submodule update

Install dependencies:

sudo apt-get install python3 python3-svgwrite python3-numpy python3-jsonschema asciidoc docbook-xml docbook-xsl xsltproc make

The test suite runs the LinuxCNC Standalone Interpreter to validate the emitted g-code, this is available in the linuxcnc-uspace package from the linuxcnc.org deb archive.

Add the GPG key that validates the linuxcnc.org deb archive:

sudo apt-key adv --keyserver hkp://keys.gnupg.net --recv-key 3cb9fd148f374fef

Add the apt source for the linuxcnc.org deb archive:

deb http://linuxcnc.org stretch base 2.7-uspace

Install the linuxcnc-uspace package:

sudo apt-get install linuxcnc-uspace

Build the manpage:

make

Run the test suite:

cd test; ./runtests

G-Coder Python module

This repo also contains a python module named gcoder that writes g-code.

It is intended to be called from a program that has an idea of some cuts it wants to make. Gcoder functions write g-code to an output file. Some Gcoder functions correspond directly to specific g-codes, and some to more complex operations consisting of longer sequences of g-codes.
