Laser Draw (LaserDRW) is a program that comes with the cheap Chinese laser cutters available on E-Bay and Amazon. The Laser Draw Inkscape Extension is a free open source program released under the GNU General Public License (GPL) Version 2.

Laser Draw Inscape Extension Features:

- Blue and red paths in Inkscape are saved to the LYZ file as vectors (everything else is transfered as an image)

- Save individual files or group of files as a zip file

Before you download:
I highly recommend you consider using
K40 Whisperer instead of the LYZ extension. K40 Whisperer was developed after K40 Whisperer and has completely replaced the LYZ extension and Laser Draw in my work flow. K40 Whisperer works with the same controllers as Laser Draw and eliminates the need for the USB key (dongle).

Extension Source files (zip file)


To install this Inkscape extension:
1. Download and unpack the zip file.

2. Copy the individual files into the directory listed in Inkscape at "Edit" - "Preferences" - "System": "User extensions". You might need to resize the window that pops up to see all of the fields and entries.
(It will also work if you put the files in "C:\Program Files\Inkscape\share\extensions" or "C:\Program Files (x86)\Inkscape\share\extensions" depending on which version you have installed.
The location above is the location referenced on the Inkscape page for user installed extensions.)

3. After a restart of Inkscape, the new extension will be available.

How to use the Extension:
1. Create your own design in Inkscape.
- Use RED lines to indicate cutting.
- Use BLUE lines to indicate vector engraving.
- Use BLACK to indicate raster engraving (this can be shapes, paths or images)

2. Adjust the size of the document to match the area you want to export (You can use "File" - "Document Properties" - "Resize Page to Content" to make the page the same size as your design)

3. Within Inkscape select "Save As"

4. Select one of the two "Laser Draw LYZ" options
- The (*.lyz) selection will allow you to save the red,blue and black features to individual files for use with Laser Draw
- The (*.zip) selection will automatically generate all of the files needed for engraving and cutting and save them to a zip file
