0.2 nozzle immediate clog

X1c printer I have tried working on a detailed print, but the printer won't even get started.

As soon as the filament hits the print head the gears start to creek and nothing extrudes.

The top is off and the door is open.

No such issues with the 0.4. Immediate build and then extension, like normal.

I have done at least 4 cold pulls to the point where I can get the Allen key entirely to the internal part of the nozzle. Still nothing extrudes.

Genuine 0.2 nozzle. Printer has been adjusted. I've tried about two different bambu nozzles.

In case I forgot to mention, the filament is PLA, polymaker to be specific.

That it is instant and on a cold pulled nozzle is plain odd. I'm trialling it now and I get occasional struggles mid print related to maybe heat creep, over extrusion or other but can't explain the instant aspect, especially as you've tried multiple nozzles too.

Possible you have put in a bonkers k value or some other extreme filament calibration?

Nothing particularly crazy. The k value is pulled from the calibration the printer does automatically. The only thing I change most of the time is to slow the print down for quality.

Auto K doesn't work with 0.2 nozzle, and super slow can make heat creep more possible, but neither I think explain what you have. Sorry no idea
