Bob,
Check out the eggbot download site,
See specifically, the eggbot sample collection,
You’ll find an assortment of plots there, some simple and some not. Start with simpler plots.

Some of them require some experience with getting good centering and grip on your eggs so don’t try a challenging plot as your first experiment. Also, if you want to visually see the eggbot “coordinate” system on an egg, there’s some plots such as

Have Fun!
Dan
