Convert images to rasterized G-code for home-made (laser) engravers

img2ngrv - Image to Engraver Raster      

Convert a pixel or vector image to G-code as commonly used by home-made (laser) engraving machines.

This particular code is tested with the LulzBot 3D printers modified for laser engraving with one of the kits sold by J Tech Photonics. The software is similar in end result to their LaserEtch tool. For other engraves, you will have to teak the (G-)code manually, especially the preamble. Luckily the program is contained in one python file.

img2ngrv's Issues

Various issues with versions of cairosvg and pillow

On some platforms, weird problems occur that seem to be related to versions of Pillow and cairosvg. E.g. saying no module named 'paste' although paste is installed.
Another one is img2ngrv/img2ngrv.py:228: RuntimeWarning: Parent module 'img2ngrv' not found while handling absolute import.

Here is what I'm mostly using that never caused problems:

>>> cairosvg.VERSION
'1.0.22'
>>> PIL.VERSION
'1.1.7'
>>> PIL.PILLOW_VERSION
'3.3.1'
