Credits

• Brian Ho modified this extension to generate compatible g-code for TimSav (Robotini GRBL)
• Marty McGuire pulled this all together into an Inkscape extension.
• Inkscape is an awesome open source vector graphics app.
• Scribbles is the original DXF-to-Unicorn Python script.
• The Egg-Bot Driver for Inkscape provided inspiration and good examples for working with Inkscape's extensions API.

Install

Copy the contents to your Inkscape extensions/ folder.

Typical locations include:

• OS X - /Applications/Inkscape.app/Contents/Resources/extensions
• Linux - /usr/share/inkscape/extensions
• Windows - C:\Program Files\Inkscape\share\extensions

you should have 2 files directly under the extensions folder (unicorn.inx, unicorn.py) and the unicorn folder as well.

Usage

• Create a document with the size of your foam board (eg. 20x30 in) and **SAVE THE DOCUMENT **
• Create some objects and convert all to paths:
  • Select all text objects.
  • Choose Path | Object to Path.
• The path cutting orders are generated based on the svg document hierarchy, you can organize your paths with the XML editor.
  • For score cuts make the path strike RED #ff0000 (mind the lower case ff)
  • For marking cuts make the path strike BLUE #0000ff (mind the lower case ff)
  • The id of the path can be set with the editor and will be retained in the gcode's comment (helps with gcode troubleshooting)
• Save as G-Code:
  • File | Save a Copy.
  • Select TimSav G-Code (*.gcode).
  • Save your file and load the new gcode

TODOs

• Draw arrow for the direction of path for view
• Rename *PolyLine stuff to *Path to be less misleading.
• Parameterize smoothness for curve approximation.
• Use native curve G-Codes instead of converting to paths?
