Eh. when was the last time a mosfet melted on anyone? not saying it can’t happen, but mosfets are at fairly reliable. as long as you’re not trying to push wayyy too much power through them; and also proper surge protection to avoid things like bad power in your house frying them.
It was a significant problem in early machines. Most now have thermal runaway protection. As long as your wires don’t short out, it shouldn’t be a problem.
And the only wires that have enough energy to be a problem are the heaters- hot ends, heated beds/enclosures.
The firmware keeps track of how much energy is going to them and will shut the printer down if the energy is inconsistent with the reported temperatures. (Aka thermal runaway protection.)
You can also usually add secondary thermistors and if they deviate too much, triggers the same result. (And the machine will usually start trilling to get attention, etc,)
I can only imagine what someone like my ex would have to worry about in those places. The idea that something- for her- is totally normal would see her facing charges for things that never happened anyhow. It’s patent stupidity.
This kid is smart, and whoever coached her… good job.
Capsaicin isn’t a spice*. It’s not even a flavonoid. That is to say, it doesn’t trigger or act against the taste receptors in your tongue.
What the stuff does is trigger the heat receptors in your mouth (and skin and everywhere else you have heat receptors.) causing your body to feel like it’s burning.
“Spiciness” is what happens when your flavor receptors get overloaded. If you want to experience it, go get fresh garlic and chew a raw whole clove. (Do NOT swallow. And be prepared for massive indigestion. Raw garlic is not to be trifled with.) or maybe take the cinnamon challenge (spoonful, hold it in your mouth. Do not swallow,)
In any case capsaicin itself causes happy-hormones to be released, as a result of the sensation of being burned through. (The sensation also causes increased heart rate and that can get excessive, too.)(the people that like super-hot peppers are masochists.)
(*Spices are technically parts of plants used for flavor that generally aren’t the leaves. So the pepper itself can be a spice, don’t get me wrong. Most are quite fruity. The vast majority of people are not using hot peppers for that fruitiness, though.)
