Process

For artwork, I ill often create something in Inkscape, Illustrator or 3D, export it as an .EPS file.

From here, you'll want to convert the EPS to HPGL:

pstoedit -f plot-hpgl src/input.eps dist/output.hpgl

Then you want to remove all the excess crap in the HPGL and optimise the pen route:

hpgl-distiller -i dist/output.hpgl -o dist/output-distilled.hpgl

Now use the optimised in Chiplotle:

$ chiplotle

>>> plotter.write_file('dist/output-distilled.hpgl')

The plotter will start drawing straight away.

Note: Worth adding a pick up pen command to the top of your HPGL incase there isn't one from your EPS
