Okay. I only ask because my Makerbot Desktop has a catastrophic bug that is causing my printer to get reeeally screwed up if I make any modifications to the part in the slicer. As in, once I import the .stl into Makerbot I have to export exactly that to .x3g--even if I do something simple like move the part to a different area on the print bed, somehow the .x3g file gets really messed up and causes my printer to go haywire. I'm just trying to avoid spending $150 only to find out I get the same problem with S3D.
