This post used to be on Posterous. I rescued my posts before Posterous shut down and am now sharing them here.
I made this version of the Baltimore Node logo the other day in Inkscape, but wasn't at home to test it. Here are the resulting plots on both EggBot and Unicorn!
The Unicorn version came out a little messed up due to my sizing the file wrong - the pen went off the edge of my sticky note pad and mussed everything up. I resized the plot to fit the sticky note fine, but had some pen registration issues with the now-crumpled sticky note pad. I'll probably try this again later with some nicer stock.
One problem that has often plagued users of the MakerBot Unicorn is the long and confusing chain of tools required to go from a nice vector drawing to a G-Code file that can be plotted from ReplicatorG.
mifga did an awesome tutorial that made it possible to understand the steps needed to work all of these tools, but it was obvious that something better was needed.
