Eggbot Coordinate Demo Using Hershey Text

thingiverse

The original was great to have, but I made these tweaks: The labels have been replaced with larger text generated using the Hershey Text extension. These labels should be now be super-legible, even on objects as small as ping pong balls. :D After looking at Inkscape's y-axis orientation and the eggbot pen-motor orientations, the y-position labels have been vertically swapped. The paths are now organized into layers named "Grid Lines", "Direction Markers", and "Labels". :) Future changes: I intend to create some additional variants for heights of 950, 900, and 800. It might also be handy to have some regular-grid designs without labels to make it easier to pencil-sketch on a reusable ball and then transfer that design to Inkscape. EDIT: Silly me, I forgot to promote Hershey Text! Download it now!http://www.evilmadscientist.com/article.php/hershey Instructions Load a spheroid into an Egg-Bot and plot away! Note that for objects as small as ping pong balls, you will need a lot of hardware adjustments before you'll be able to plot all the way from Y=0 to Y=1000 without any collisions. That's the main reason I want to make a 950-tall design (since it's a small sacrifice in surface area for a huge gain in usability). Also, trying to fine-tune my machine for this plot got me to realize that the egg and pen motors were not perpendicular! The easiest way to test this is to just turn the motors off, and drag a servo-down pen back and forth between the poles. If you can see/feel a major angle, you'll might want to fiddle with your angle bracket placements. :)
