Description

When I first heard of Graffiti Markup Language (GML)[1] I was like “An XML format for graffiti? Pfft!” Then yesterday I was like “Wait, I have a pen plotter.”

There are a ton of tags for you to play with at 000000book[2], so go get some files and start tagging … with post-it notes!

Description

One problem that has often plagued users of the MakerBot Unicorn[1] is the long and confusing chain of tools required to go from a nice vector drawing to a G-Code file that can be plotted from ReplicatorG.

mifga did an awesome tutorial[2] that made it possible to understand the steps needed to work all of these tools, but it was obvious that something better was needed.

So, I made a mashup of scribbles.py[3] and the Egg-Bot Driver for Inkscape[4] to bring you the inkscape-unicorn extension for Inkscape!

Once installed, this extension allows you to save files in “MakerBot Unicorn G-Code (*.gcode)” format!

Learn more, download, and contribute at the GitHub page for this project:

If you’re desperate, you can also download the zip file attached to this thing, but it is guaranteed to be out of date. Please get the latest version from GitHub. :)

Thanks to langfordw for the original Unicorn Logo[5] used as an example on this Thing.

Instructions

From the README:

Install

Copy the contents of src/ 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

Usage

• Size and locate your image appropriately:
  • The CupCake CNC build platform size is 100mm x 100mm.
  • Setting units to mm in Inkscape makes it easy to size your drawing.
  • The extension will automatically attempt to center everything.
• Convert all text to paths:
  • Select all text objects.
  • Choose Path | Object to Path.
• Save as G-Code:
  • File | Save a Copy.
  • Select MakerBot Unicorn G-Code (*.gcode).
  • Save your file.
• Preview
  • For OS X, Pleasant3D is great for this.
  • For other operating systems… I don’t know!
• Print!
  • Open your .gcode file in ReplicatorG
  • Set up your Unicorn and pen.
  • Center your build platform.
  • Click the Build button!
