REMOVE THE NEW FILAMENT
•
Lower the temperature to 90 degrees (for PLA) or 110 degrees (for ABS)
•
Once the temperature has been reached, pull the filament out with a quick, firm pull
•
Check the color and shape of the tip of the filament; the goal is to have a clean, cone-shaped tip
•
Repeat step 3 and 4 until the filament comes out without any residue and has a cone-like shape
RE-ASSEMBLY
•
Insert the bowden tube through the tube coupling collet all the way down into the PTFE coupler
•
Place the clamp clip around the tube coupling collet so that it secures the bowden tube
