YouTube is treacherous. Official Monoprice video shows correct procedure, but skips explaining how to remove the tube (you have to depress the blue plastic flange as I found from another video), but there's a lot of confident videos telling you to disassemble the whole damn head.

It is truly humbling how much this very simple device can take you far beyond your sense of competence. Rheology is a bitch.

Motors, electronics... they're conceptually simpler, and the gap between the textbook and reality is small. But when you're talking a gooey melty viscous fluid going through an extruder and then cooling and hardening on a plate.... textbook understanding doesn't get you far.

Something I didn't realize in like 9 years of theory focused engineering school is just how much of what you need to know is basically only knowable through bug-fixing. Engineering education is 10% concepts/design/theory, and 90% bug fixing metis.

Bugs also thoroughly violate your sense of proportions of value/investment.
- The triviality of a bug has little correlation to how long it will take you to discover/fix it. That's entirely a function of experience.
- The cost of the bug is often the value of the whole project.

Bugs are basically insulting. They don't respect what you think you know. Only how strong your Fingerspitzengehfül for traversing the troubleshooting tree is.

To a first approximation, your engineering ability is the number of bugs you've fixed

Ability to unearth bugs? Software engineers tell me I have an uncanny ability to go off script during testing.

if you have an uncanny abiity, your bug-fixing number should go up much faster than average since you'll fix more bugs/unit time than others

Hmm that makes you a tester/QA person rather than a full-stack developer/designer I think? I was pretty good at that too as PM. My software team used to complain that I’d find bugs within minutes of a new build that would likely not be found for months in production 😈

They did call me testing, testy, something like that yeah.
Full-stack lol. When I say I'm a surface scientist that describes my programming abilities too.
