So I have made a 20mm cube in Autodesk Inventor, then I saved it as an STL and imported it to S3D. I slice it with S3D, load it to an SD card, put it in the print hit start, and nothing happens. I have done the same procedure with other files and it works just fine. I haven't changed profiles or used any different setting, I have only changed the model. Keep in mind I am a newbie at this and have only been printing for 2 days now, so it might be something stupid, but any help would be greatly appreciated.
