As many of you now, version 1.1.3 of the Creator software includes support for MakerBot printers using whpthomas' great GPX plugin (https://github.com/whpthomas/GPX). We've integrated this tool into the software so that all you have to do it enable the "Create x3g files for Makerbot printers..." option and the software will run the GPX as a plugin to produce both .gcode and .x3g files automatically.
You can then print this .x3g file the same way you usually do by copying it onto the SD card and using the build-in LCD panel. It's a big step forward for MakerBot users and a big thank you goes out to whpthomas for all his hard work!
If you are using an earlier version of Creator and want to download the standalone GPX binaries, you can find them below.
