[Roxy]

Roxy, may I ask what version of slic3r you are using? I tried using the latest 1.1.6 with repg and it did not work. Maybe I should try a different version?

I'm usually running the 'experimental' release. My printer is broke right now, but if it wasn't I would be at 1.1.6 I'm actually at 1.1.0 right now. But with that all said, you can run Slicer as a stand alone program. You can create a short cut icon on your desktop and just double click it. That is how I prefer to do things because I have more control. But you can also just let your printer program run it for you. One of the options on Slicer is what type of GCode it should produce. I don't know what Replicator-G's type is.... But you need to set it correctly in Slicer. You do that at:

Printer_Settings / General / Firmware / G-code_Flavor
