partial clog cold pulls not working--is there a current knowledgebase page for this?

Hi everyone,

New to Prusa, 3d printing for 3 years now.

I've done about 40 prints on a new Core One + (Prusament galaxy black PLA and Prusament lipstick red PLA).

Have what I believe is a partial clog. I've done 5 cold pulls with PLA and also some eSUN cleaning filament I've used on my Anycubic Kobra 2 successfully in the past). No luck--still clogging off 10 minutes or so into any print.

I want to know if this page:  https://help.prusa3d.com/article/clogged-nozzle-hotend-mk3-5-s-mk3s-mk2-5s_2008

is applicable to the Core One + or if there is another support page that is more current.

Thanks!

Chris

When printing the PLA, I assume you have the top vent open?

Yes, I always check at the start of the print.

Interestingly the test Bench that came with the printer continues to print easily while objects of similar height that I send to the printer have layer breaks at heights well within where they should have happened with the Benchy.  I'm using the latest version of Prusa Slicer and stock PLA settings with 0.2mm layer and the stock 0.4 mm nozzle, so now I am more confused as to whether this is really a partial nozzle clog.
