Step 1 Getting the correct PTFE tube
This guide will take you through the entire process of how to disassemble the MK3S+/MK3S/MK2.5S/MMU2S extruder, replace the PTFE tube and assemble the extruder back.
Note that the upper part of the MMU2S extruder is slightly different from the single material MK3S+/MK3S/MK2.5S, but the disassembly is the same as it focuses on the lower part.
This guide doesn't work for the MK3/MK2.5 type of extruder!!! See the How to replace a PTFE tube (MK3/MK2.5)
