First lesson of 3D-printing. When the manual says to ensure the filament should have a straight end before inserting it in the machine, do so.
On the bright side, I've learned how to unjam the machine.

Chatbots — LLMs — do not know facts and are not designed to be able to accurately answer factual questions. They are designed to find and mimic patterns of words, probabilistically. When they’re “right” it’s because correct things are often written down, so those patterns are frequent. That’s all.
