MMU-to-Extruder PTFE tube disassembly
Take the MMU-to-Extruder PTFE tube with the Festo fittings QSM-M5.
Remove both Festo fittings on the old PTFE tube.
Hold the Festo fitting by the metal part and press the blue collet in. While the
collet is pressed, first press the PTFE tube in, then pull it out entirely.
MK3S+/ MK3.5 owners: Save the Festo fittings for later use. Discard the PTFE
tube so you don't confuse it with a new one later on!
MK4/MK3.9 owners: Throw the Festo fittings and the PTFE tube away now! Your
package includes new Festo and PTFE tube. Mixing them may lead to issues!
MMU3 is designed to work with differently-sized PTFE tubes. Reusing MMU2S
tubes during the assembly of MMU3 will result in incorrect operation.
