Maybe I need to reconsider S3d. I have a part I need to print out. It is printed with Ninja-Flex. I can't get a good print because it needs supports (I think). All I get is a stringy mess with dual extrusion. I have made so many adjustments to temp, speed, supports, no supports, etc. Maybe I need another opinion. Can I send you the file to print with S3d to see if it comes out any better? Or, maybe you can look at the file and suggest a better way to print it. I'd attach the file here but don't see how to do it.
