RE: Immediately severely clogged after only 2 test prints
It's the same here. I printed my first parts in PETG and everything was fine. Then I switched to PLA and the first print clogged the original 0.4 nozzle. I used the default settings and the generic PLA profile. Luckily the filament broke off just above the nozzle and I had a 0.6 nozzle on hand so I could continue printing. The 0.4 nozzle is still clogged, heating it up to ~260°C hasn't helped so far. I've never had the problem with my other printers that I couldn't clear the nozzle by heating it up and pushing the filament through. I have also had no problems with clogging with the 0.6, although I have also used standard settings here. The printer is in the basement at ~15°C room temperature, so cooling should definitely not be a problem.
RE: Immediately severely clogged after only 2 test prints
What filament were you using?
I'm having this exact same problem printing Azurefilm Matte HS PLA using the generic PLA, and lowering the temp after unclogging the nozzle didn't solve the issue with this filament as the nozzle got clogged again.
RE: Immediately severely clogged after only 2 test prints
Do you guys use any filament dust filter? The dust, which then burns in the nozzle, is the main source of clogs. Especially with HF nozzles.
I haven't experienced any nozzle clog since I have started to use filament dust filter years ago.

Interesting point ... I had to look it up what 'dust filters' are so the answer is no :p
What kind are you using ? I see alot of remarks that either have issues with sponge materials then clogging up and/or question its effectiveness.
After adjusting my PLA material settings in Slicer, I haven't encountered the clogging problem again. I noticed also that the 'display name' in the drop down box on the main screen is actually different then the name one chooses in the material subscreen. There the name clearly indicates the PLA settings are for core HF. On the main screen the PLA name is exactly the same as for my MINI so hence the source of the confusion and error .. there was visible not any indication that I had to change the PLA as both displayed 'General PLA'.
I did have 2 blue screen dumps but that's another thread I suppose 😛
Kind Regards,
Steven
RE: Immediately severely clogged after only 2 test prints
I use this one: https://www.printables.com/model/43403-filament-dust-filter-parametric With pieces of cheapest plastic sponge for washing dishes. Sometimes I clean the dust accumulated inside with a stiff paintbrush.
RE: Immediately severely clogged after only 2 test prints
No, I don't use dust filters for my filament. And my printers are in the basement near my “woodworking area”. I do occasionally clean out the dust, but I have never had such a clogged nozzle on any other printer (equipped with e.g. Revo HF nozzles), and the PLA filament I had the problems with came directly from one of the other printers. So I can definitely rule that out as the cause in this case.

RE: Immediately severely clogged after only 2 test prints
I am having the same issue I think. On my second print I started hearing clicking and then noticed no plastic (PLA) coming out of nozzle. I had no time to debug and won't until the weekend when I will contact chat support. Bummer that this seems to be a problem for a lot of people.
RE:
Long time Prusa owner here (5+ years).
Exactly the same problem here. 3 different PLA rolls, Prusament and 2 others. Core One factory assembled. I get clogs on 70% of longer prints. I have needed to do so many cold pulls with the hotend outside the nextruder in the last week that I have now managed to damage my hotend cable I think, It gives a red screen and a warning and the hotend does not warm up anymore. I am PISSED. I have no problems with clogging on my MK3S+ with MMU3 using the same filaments, in the same room, same temp, same "dust". I am returning this shit printer if this does not get fixed, I paid 1300 euros for a printer I can't use.
PS. I am using a dust filter. No improvement whatsoever.
