If it snaps, do NOT use it. You must dry the material before use. This prevents unnecessary and avoidable clogged hot ends.//       * //To test if material is brittle or water logged, bend a piece of the filament in half with your fingers.

 | To perform a successful cold pull, heat the nozzle 5-10°C above the normal temperature used for your material. Allow it to heat up and then extrude a moderate amount of filament, about 30-50mm to ensure there is filament in the nozzle. After that has been performed, lower the nozzle temperature to 90-100°C, this may take several minutes. Once it reaches the temperature designated, depress and hold the extruder arm and firmly pull on the filament. You should feel it release with a gentle pop and feel pressure on it as you continue to pull it. If you performed a successful cold pull, the tip of the filament should be in a conical shape like the inside of the nozzle. You should most likely also see thin wisps of filament surrounding it. If there is another color(s) other than the one you're using, perform a cold pull again, as this indicated there may be a partially clogged nozzle. | To perform a successful cold pull, heat the nozzle 5-10°C above the normal temperature used for your material.
