+ | | **How do I perform a "cold pull"? | ||
+ | | 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. | ||

+ | If you're unsure of how to perform this and have taken either the 3D101 or the 3D Printing Accelerated Assessment, contact the FabLab Area Lead for assistance. | ||

+ | | **What do I do if I attempted to perform a cold pull, but it was unsuccessful? | ||
+ | | Attempt to perform a cold pull once more. If it still fails, leave a tail of the filament, about 12", sticking from the extruder. Alert the FabLab Area Lead of the issue and discontinue use of the printer. | ||
