That ridge looks like it’s part of the model. Can you confirm its not supposed to be there?

I never met a Kelvin irl. Just a Celsius. He got really hot overtime.

Don’t worry, you did good.

It is necessary, just not EVERY single time. I remember watching a video that provided a simple and effective method to manually extract the filament. However another user here claims Bambulabs can automate to waste less filament.

Let me know it works.

I use the P1P.

What’s annoying is that it doesn’t HAVE to purge. I’ve experimented with changing the filament manually without pausing and the results are good.

Any chance you’re using Orca Slicer on Fedora?
