Ultimaker S5 AA nozzle not extruding filament

[zeeg617 0]

Hello,

 

I have been experiencing some issue with one of my nozzle recently. As the title said, the AA nozzle does not extrude filament during printing. However, when I load the new filament the filament came down from the nozzle normally. It is only during printing nothing comes out. Is there a fix to this issue?

 

The things I did before the issue occurred were:

 

1. Printed with CPE+

2. Switched to PLA

 

Best

Did you do a really good hot and cold pull to make sure the CPE+ was fully out of the core?

No, I did not. How should I do that? Thanks.

I am not sure where to find the info...I think @fbrc8-erin had a series of instructions concerning this. I tagged her so that she can hopefully gather the links for you.

What about the official "print core cleaning maintenance instructions":

While you're at it - take a look at all other maintenance tasks too... 🙂

Thanks for providing links for him. I could not think where I found it before.
