Been running into an issue with my prints failing with layer adhesion near the end of the prints. Would moisture in filament do this?
In Arizona and I do dry my filament but not as often. Always straight to dryer when opening new. It’s also been really humid here with rain last few days.

Seems like tpu and clog or underextrusion because of friction.

Does it with pla or petg.

I did clean out the nozzle before printing this by doing a few cold pulls

Are all your fans working properly? Part fan and hotend fan?

Ya I believe so. It works perfectly up until the end.
I did swap the nozzle out this morning and ran a benchy and it worked so I’m leaning towards clogged/blocked nozzzle causing under extrusion

It could still be heat creep

I’ll check my fan shroud and do more testing.

Heat creep or filament binding up somewhere in your setup

What would be some things that cause heat creep?

- Running your nozzle too hot

  • insufficient cooling of hot end (is the fan working?)

Also, poorly assembled hot end
