i covered the block in kapton tape and a week later of use the thermistor was gone and all that was left was 2 bare black wires. woops. another time i left the printer while it was printing and a hour later i checked it and for some reason the temp was reading 340c and i could see smoke coming out of the nozzle. this was on a ender 3 with a max temp of 260c with all the protections enabled in the firmware. pretty scary stuff. obviously i took the whole thing apart and rebuilt it many times after and it never happened again but i still don't have a single clue how it happened.
I once had to replace part because the printer was broken I didn't know what was broken and now I sea this video and it did exactly this I tryed to print and it started dripping verry liquid plastic and releasing smoke from the nozzle end
The smoke in the first part was noxious fumes from the PTFE burning up. Very bad for you.

It can get hot enough to melt the aluminum block in some cases over 600c.
My 3D printer is not heating higher temperatures than 220ºC. Any clues?
what happens when the 2 wires short?
fried the part in the board. Had to buy new board.
