Text for Eggbot
From Evil Mad Scientist Wiki
To make text in Inkscape, you can the Text tool to make text in the "obvious" way: Select the text tool, click somewhere on your page to indicate where you want to put the text, and begin typing to enter the text. Before sending the text to the Eggbot, select from the menu Path > Object To Path to convert it from editable text to curves (paths) that the Eggbot can draw.
To create fills for outline fonts, see Creating filled regions.
Another method is to use the Hershey Text extension, which is included with the Eggbot software. It makes single-line fonts that draw very efficiently and cleanly. You can read more about using it at Evil Mad Scientist
