Modified to output gcode that is compatible with K40 style laser cutter running Marlin (https://github.com/lansing-makers-network/buildlog-lasercutter-marlin).
I couldn't get the original version from LMN repo to work with LMN's Marlin as it never set the laser intensity on the M3 command.
This works form me, but YMMV. Very limited testing. Never leave your laser cutter unattended while it's powered/operating. Keep a fire extinguisher close by, wear saftey goggles, and be afraid!
USE AT YOUR OWN RISK!
10.17.14 - A little more testing reveals that G02 (CW ARC) and G03 (CCW ARC) moves are problematic. Not sure if it's the modifications in this fork, the original THLaser, LMN's Marlin, Inkscape, or some combination that is causing the issues.
Basically, you should consider this pre-alpha code. Examine the exported Gcode and do test runs on cardboard/paper before trying to cut on valuable stock.
Also: G28 at the end of the job doesn't seem to be working at the moment, at least not when running the gcode on my machine.
10.19.14 - G02 and G03 really screw things up, so I've set the default min_arc_radius to 500 to force all cut moves to be G01. That has it's own issues. At this point I wouldn't recommend using the Gcode from this for any real jobs.
THLaser Inkscape Plugin
-----------------------
This program is an Inkscape extension for exporting a set of paths as
gcode script. It is primarily used by members to the think|haus hacker
space (thinkhaus.org) for use with their laser cutter. As such it is
customized to suit our needs and so may not be your best choice if you
are looking for a general purpose Inkscape to gcode script.
This script is a fork of Gcodetools v1.2 written by Nick Drobchenko and
is released under the same license (GPL v2).
Installation
------------
Copy the files thlaser.py and thlaser.inx into your Inkscape extensions
folder. Fire up inkscape and you will find the plugin under Extensions ->
Export -> THLaser GCode Export.
Keyboard Shortcut
-----------------
You may find it handy to assign the extension to a keyboard shortcut.
Include something like the following line to your inkscape keys
preferences file (this will bind the plugin to Ctrl+\):
This Inkscape extension is derived from THLaser. It converts paths to gcode for laser cutting. Unlike THLaser, ShinyLaser allows you to set different feedrates for traversal and cut moves. The gcode output is intended to be run on a laser cutter running Smoothieware.
