I just bought some cleaning filament for the times I suspect a clog. eSun’s instructions are sparse enough as it is, not included in the package and Intservo only has minimal recommendations. All the instructions I’ve found for it involved just running it through at the temperatures the previous plastic used or the next plastic will use. Temperature recommendations for cold pulls seem oddly lacking. Does anyone do it that way? Some people call it “atomic cleaning”.Edit: I did find Intservo’s instructions: http://ift.tt/1skQqdF I don’t think it’s enough for proper cleaning, see the notes. http://ift.tt/1qUCjdx
