My housemate has a Makerbot Replicator 2.
However, it does not accept G-code, and the Makerware software is propriatary, Windows-only.
So I cannot use it without borrowing my friends Windows laptop.
Others have hit the same problem, and it does look like there are ways to convert from gcode to the custom X3G format.
