I loaded Slic3r onto the Raspberry Pi, but it only runs in command line mode. When I try to launch the GUI, it crashes. I saw on another website where someone successfully loaded Slic3r including the GUI on their Raspberry Pi, but they started from a Raspbian image, whereas I'm using NOOBS. I'll download Raspbian and give it a shot in a few days.
I also got a nice compact wireless keyboard and mouse from Amazon.com. It worked right out of the box with the Raspberry Pi. Man, I really like this little computer.
