The very top layer would also have high cooling fan, no?
It could be your cooling fan is just waaaay too powerful, and causing the plastic to not flow and bond correctly to the lower (or following) layers.

I’ve been seeing your posts on Masto, but I guess I’ll reply here.
I don’t know what printer you have, and I don’t know if the feature works for all printers, but could you try and use PrusaSlicer to visualise the print where the issue presents itself. More specifically, you could get some interesting data from the “actual print speed” view. That way you can see what speed the printhead reaches.
However, based on your description:
Could you be reaching the limit of what your printhead can melt? Would it make sense to calculate the actual flow through your nozzle at those high speeds? Finally, how much part cooling do you have setup? Have you tried a skirt to keep the temps more consistent?


I’m someone who builds cloud infrastructure for a living. I only touch AWS (Amazon), but the same applies to Azure (Microsoft) and GCP (Google).
Kagi is private. Saying that they “rely” on Google because they use GCP is akin to saying that the US Army relies on General Motors because they use Hummers. It’s just a provider. They’re renting virtual machines, compute power, storage, and network bandwidth nothing more. You can use GCP/Azure/AWS without your data ever being visible by GCP/Azure/AWS. It’s not because you use GCP that you have to use AdSense/Analytics/Fonts, etc. They are completely separate.
Politicians would have a field day with all the cloud providers if using one thing forced you to use everything.
It could be a case of too much cooling, while simultaneously being too much heat.
If you’re blowing so much air that the filament instantly solidifies when it leaves the nozzle, it’s not going to bond with anything else. It’s also interesting that the first layers are fine (when the part cooling fan is typically not running), but problems start when the part cooling fan turns on.
Have you tried without part cooling at all? Another thing is that your part cooling might be cooling down the tip of the nozzle, causing tiny partial clogs, which are cleared every so often by friction.
Did you notice a difference in print speed when you slowed down? As this is a small print, it could already be as slow as it will be due to minimum layer times.
It could also be that the nozzle spends too much close to the print. What happens if you print 2 or 3 of them?
This is typically more of an issue with PC where you don’t have a part cooling fan running, but maybe it’s the case here too?
Definitely doesn’t sound like an issue with Tor Browser in Strict Mode. /s


The simple fact that buying a $300 device and to “not expect software updates” is not considered a scam is hilarious to me.


Interesting that the extra 10° makes such a difference for ASA and ABS.
I recently started printing with ASA in my enclosed MK4. I might have to try this.
There’s an explicit clause that exempts politicians from the ban. They get privacy because they need it, but nobody else does.
