MMU the steel tubes is necessary?
Are the metal tubes inside the quick connectors really necessary?
I ask this question because I just installed the MMU in the prusa, but I feel that these metal tubes are too narrow for the filament, so you could work without them or they really are very important.
Thank you.

As far as i can tell they are not necessary. I've had tons of prints with higher quality without them.
Someone beat me to my own topic lol.
Re: MMU the steel tubes is necessary?
If the steel tube is too narrow, the filament may not be able to enter the ptfe. My advice : get a better filament, because if that one don't have a (almost) regular 1.75mm diameter you will encounter many problems with it. The mmu isn't forgiving with bad filament.
