I have saved one such hot end that had gotten plastic all over itself by heating it with a gas torch. The PLA burns off. Burned off the coloring on the aluminium too.
People either don't have enough water or have the heat too low. Enough water will give the pasta space and enough heat will agitate it.
Now that I'm here, also put a lot of salt in ypur pasta water. It should be as salty as the sea. If you make a sauce, the pasta water is a good start, the starch will make it sticky. Source: Samin Nosrat.
How...? Mine is literally 2 bolts and the bowden tube retaining bolt? Plus of course the sensor and resistor cartridge. I have no experience of direct feed hot ends tho.
Fines are usually paid to a government whose citizens have suffered. The government can then use the money for the benefit of citizens... Given of course that the government is generally inclined to such a thing.
On some level I agree with the sentiment that China's military power aspirations seem to be primarily regional with soft power as we zoom out I would argue for "Don't listen what leaders say, watch what they do".
You don't build giant landing craft unless you consider a marine landing warfare scenario as credible. You don't build aircraft carriers unless you care about power projection. You don't need ballistic missiles unless your enemies are far away. All of these things cost money you could otherwise spend on keeping your citizens happy.
There are a lot of verifiable and expensive signals about China's power posture transitioning towards a more expeditionary one. Now, they might end up carrying the big stick and speaking softly, which is better for everyone – even if the PRC ends up getting their way – but that just means the hard power lever was used in a different way.

Next time I tried it, I melted the hot end.
