Frequent Nozzle Clogs Despite Using Default Settings
My first three prints went smoothly. Since then, the print head keeps clogging. You can tell because of the clicking sound and the fact that no filament is being extruded. I have tested both nozzles that came with the printer, and the problem occurs with both. I am printing with Prusament PLA using the 0.20mm BALANCED profile. Can someone help me? The print then looks like this.
I’m a bit frustrated, because as a beginner I thought it should work with the default settings.

Clogging or not feeding? It sounds like you are able to get the print going again between failures?
Not Feeding, start here

It is clogging. I have to pull the filament out of the nozzle to be able to print again

My factory-installed CHT high flow nozzle also clogged with Prusament PETG (all standard Prusa settings). After swapping out that HF nozzle with the factory standard hardened nozzle I have not had any issues. Have you tried the Cold Pull from the menu?
RE: Frequent Nozzle Clogs Despite Using Default Settings
Although I haven't had any issue with the HF, I plan to replace with a diamondback hardened nozzle and keep it that way. Print quality suffers at these high speeds the HF work at, using standard nozzle profiles anyway.

I had a clog resulting from a filament change. The root cause seemed to be my nozzle being not properly seated.

Moderator comment,
Please don't bring Chat GPT or other AI responses into the forum. we are trying to keep AI Out.
this post is in the Core One forum, where the nozzles normally supplied with the printers are one piece nozzles with no ptfe in the extruder, there is no adjustment between the nozzle, heatblock and heatbreak with normal Nextruder nozzles, and no indication that this was a nozzle adapter with a V6 nozzle, CHATGPT didn't know that and gave false information.
regards Joan
Ignore that Chat GPT response: it is out of date and wrong: possibly dangerously so.
In case this is a genuine clog perform a cold pull as instructed here: https://help.prusa3d.com/article/cold-pull-31702-core-one-35702-core-one-l_930551
Although not showing all the classic symptoms there are enough stray whisps and fragments to make me wonder; how are you drying your filaments?
When starting a print do you see oozing from the nozzle while the bed is heating? If so, definitely dry your filament.
When you pull the filament out of the hotend - is there a narrow, scooped section just before the end?
If so, open the idler cover and blow dust out of the gears.
You *might* have a slightly off idler tension - but don't touch it until you have worked through the above, it is no more than a quarter turn off if at all. @ruebarb has given you the correct link (above.)
This is a new machine so unless you can see scratches or chips in the nozzle I will rule out nozzle problems for now.
Try printing with a quality setting. Try printing in stealth mode.
... and you are about to have another problem ...
There are fingerprints all over your print sheet, these will soon affect you first layer adhesion and cause a slew of other problems. Clean your print sheet. Look up the many threads here about the best procedure.
Come back if problems persist.
Cheerio,

Appreciate the participation but I think by now (most of us) know how to access an AI for "help". Please stop copy/pasting ChatGPT responses. It just clutters up the thread and can at worst give wrong information and cause more problems than it solves.
