If you would like some more free G-code to just drive the machine around, you might want to try cutting (drawing) some spirographs. Here is a link to a tool to produce them and other designs. Just download the file, unzip it, and run it.

Here is a link on how it was developed.

Mounted a 400W 28000rpm laminate (trim) Router this weekend on the jrgo. Downloaded the spirograph program suggested by spalm. Cut out the Flower2.spr example as the "First cut" on the jrgo. I've attached a pic of the sample cutting. I can see I'm going to need a "dust collection" system on this thing! Cough!
Working on a video of the cutting that I'll post in a few days...
