What is the purpose of the long PTFE tubes?
What is the purpose of the long PTFE tubes that go into the MMU2?
From what I can tell, the only purpose is to act as a channel to the buffer. If I am not using the buffer, then are they serving any purpose other than making it more difficult to insert filament? Would cutting them down to 50 mm or so have any impact in a non-buffer scenario (like auto-rewind)?
