FIlament loading/loading works on 4 places,, only on 1 not

SO my problem is that the filament change works fine on place 1,2,3 and 5. Only on place 4 does not work. Filament gets stucked in PTFG tube between selector and extruder, and then is not possible to move in our out, only by hand.

I tried all sort of stuff already but without succes. 

 

Any ideas?

 

Thank you

What have you tried?  (So that we can only suggest other things?)

I assume you've tried different filament in that location.  Have you tried checking the bondtech gear alignment in the MMU2S for that path?

Check if the filament path has low friction for that path when pushing and pulling filament by hand.

If friction is the problem (or even if its not), I recommend this mod:

So my problem is that the filament gets stucked in the PTFE tube between selector and extruder. When i remove the PTFE tube, filament moves easily. 

In place number 4 i have PLA filament from Prusa, on other places i have PETG filaments inside.

It seems that PLA filament is to dick to go through the PTFE tube and it gets stucked.

Just to update, maybe someone will find this useful.

Yesterday i have sucessfully printed my first part with 5 filaments (Using PETG)

Today i wanted to printed one part with PLA + PVA Support filament and the filament gets stucked every time in PTFE tube from selector to extruder. Both of the filaments get stucked.

 

So today i ordered bigger PTFE tubes 2mm-4mm, so hopefully my problem will be solved. Even better would be PTFE tube 3-4mm, but i have to wait for this one another 3 weeks. 

I´m also printing this part https://www.thingiverse.com/thing:3233579 and i have also ordered 5 Fittings M10 jst to be sure to get nice path for the filament.
