Juicy-gcode: A lightweight SVG to GCode converter for maximal curve fitting

Hackage Travis Appveyor

Overview

Juicy-gcode is a configurable SVG to G-code converter that approximates bezier curves with biarcs for maximal curve fitting.

Installation

The easiest way is to download one of the pre-built binaries from the releases page. Alternatively, you can build from source code as follows:

Usage

⚠️ Breaking change: Since version 0.2.0.1, default DPI is changed to 96 and the option to mirror the Y axis is removed (it is always mirrored now for correct result)

The easier way to use juicy-gcode is to simply provide an SVG file name. The generated GCode will be written to standard output.

$ juicy-gcode SVGFILE

Alternativly, you can provide an output file name as well.

$ juicy-gcode SVGFILE -o OUTPUT

Sometimes you want to overwrite some default settings. These are the

$ juicy-gcode SVGFILE --dpi 72 --resolution 0.01

Some firmwares (e.g. Marlin) can handle bezier curves directly. In this case you can command juicy-gcode not to approximate bezier-curves but emit them unchanged.

$ juicy-gcode SVGFILE --generate-bezier

Configuration

The generated GCode is highly dependent on the actual device it will be executed by. In juicy-gcode these settings are called GCode flavor and consists of the following:

These settings can be provided by a configuration file. The default settings are made for being able to test the generated GCode in an emulator e.g. with LaserWeb or my hanging plotter simulator.

gcode
{
   begin = "G17;G90;G0 Z1;G0 X0 Y0"
   end = "G0 Z1"
   toolon =  "G00 Z1"
   tooloff = "G01 Z0 F10.00"
}

In the case you want to overwrite it, copy this favor to a text file and modify it according to your need. Then use juicy-gcode as follows:

$ juicy-gcode SVGFILE -f FLAVORFILE

Future development

Juicy-gcode was originally developed as a testbed for my hanging plotter project, but over the years it reached maturity and became a really usuable tool. My main idea for further development is to turn it into a tool that can drive CNCs in 2.5 dimensions (e.g. carving, engraving) with just one colored SVG file.

To be able to test and enjoy that software, I need a proper CNC. Please consider donating a small amount for that purpose, or donate an actual CNC if you have a spare one for whatever reason.

Collected so far: 102.47€ Target: >= 209€

Thank you so much for all people supporting the development!
