Hello, folks.

I'm using the Spool Holder & Buffer for Core One MMU3 Community Version by Sam:

https://www.printables.com/model/1378191-spool-holder-buffer-for-core-one-mmu3-community-ve

Before this, I tried a couple of other buffer designs, and they all had the same issue.

Whenever the printer unloads filament from the nozzle, the filament gets kinked and bent inside the buffer. Then, during the next load, it gets stuck and can't enter the PTFE tube because of the kink. Quite often, when I try to straighten the kink, the filament snaps.

Has anyone else experienced this issue or found a solution? Edit: The printer I use is regular core one if it matters.

I have these blobs forming on my purge tower and eventually they stack up get big enough for my printer to collide with them and cause layer shift how do i stop it from happening

im using default PLA settings with 0.4HF nozzle on core one
