Feeder making noise after switching material (UM2+)

[yvest 18]

Hi everyone,

Got my UM2+ last week and I noticed that after changing my material recently, the feeder started to produce some cracking sound (see / hear video here https://goo.gl/photos/i1ahZU77kq2aUYdUA) while printing. Sometimes it goes away but most of the time it's there.

What I did notice while changing material is that when reversing, there is typically a very thin material being reversed which has a thicker part at the end. The thin material is completely removed but the thicker part seems to cutoff and remain within the feeder. Probably reason for this problem to start.

So I mainly have 2 questions:

- How do I best resolve this problem / sound?

- What is the best way to remove the material to avoid some leftovers remain within the feeder?

Many thanks in advance for any tips / suggestions.

Yves

My method is to stick this thing in the feeder just before the part with the blob and string is reaching the feeder and than manually pull out the filament. Works perfect.

To resolve your current situation, just open the feeder and clean it. See here for help;

Thanks Ultiarjan, I guess I didn't yet fully understand why these buttons / levers were there on the feeder where now I assume it enlarges the opening. So your trick seems to make perfect sense to avoid the problem I encountered, thanks for that.

Also the disassembly instructions seem very detailed, will look into that later this week.

Many thanks!
