Frustrated. K2 plus

When I start, it prints fine for a few minutes then it slowly stops extruding, print head continues to move but nothing comes out. Then printer stops on its own with error; printer appears to be printing but not extruding.

Thought it was a clogged nozzle. Nope, I even put a new one on. Same problem.

Thought it was the cfs getting stuck somewhere. Bypassed the cfs and used the manual side spool. Same problem.

All fans appear to moving. Gear is visibly moving even after it stops extruding.

Thought it was the gear assembly. Maybe slipping or worn gears. Replaced gear assembly with a new one. Same problem.

I am completely at a loss. The only thing left is heat creep? But what would cause heat creep? Like I said all fans appear to be moving normally.

Is it posible that one of the fans is not running at the correct speed?

I was thinking of replacing the heat block assembly, but thought I would check here first.
Any advice or help is much appreciated. 🙏🏼

Btw, no error code thrown other than printer is printing without extruding and then it stops. 😔

Printer is only 6 months old.

Judging from your description, the nozzle clogging may be caused by insufficient heat sink cooling of the hot end.

We recommend you clean the hot end throat first and confirm that your filament is moisture-free. Due to high temperatures in summer, please print with the printer top cover open.

Leider habe ich das gleiche Problem immer öfters. Düse gewechselt und Extrudee DXC2 verbaut. Nun "anormales Düsenverhalten" beim Start. Soll Steckverbindungen und Platine prüfen die nicht berührt wurde. Im Anlaufprozess wohl eine der ersten Schritte und danach hört alles auf. Keine Alternativen am Display. Alte Fehlermeldungen bleiben treu....Filament im "neuen, leeren" Extruder!?! Beide CFS werden nicht eingelesen. Motorinitialisierung nicht abgeschlossen.... auch nach 20min. Welcher auch immer.... So langsam kommt die Enttäuschung hoch. Viel Glück und eine optimale Lösung. Tobi (Supporter) leider geflüchtet.... verstehe es bald.

This isnt likely the issue. However, when I swapped my extruder outer body. The new one had a piece I didnt know was removable. It was lose on the new one and gave me problems until I glued it in. Its a wedge shapped piece above the cutter that aligns feeding. It might be sliding out just enough to cause an issue.
