Inkscape + Gcodetools + Laser

The simple way is the J Tech plugin:

Inkscape Laser Plug-In

With Inkscape Gcodetools plugin:

IMPORTANT: Every time you make any of the above steps you need to select the object (OK)

Image 1: after selecting the object, select 1st option “Object to Path”

Image 4: remove the line selected

Image 5: change “feed”. This is the speed of moving with laser ON. In my case I’m using a red laser from a DVD rom burning at 1.4mA to cut some black vinyl.

Attention on the parameters on the other images especially to the Z settings

On the last image you will generate the Gcode. BE SURE to select the “Path to Gcode” tab before Apply.
