I think my PLA has absorbed water, because my printer is periodically hissing

@ChlorideCull wet PLA will pop when it’s extruded. That’s not a sound I’ve heard a printer make before.

What temperature are you printing that PLA at?

@shyra 200 C, painfully dialed in lol

it will pop if the steam gets trapped when extruded, but this hotend is absolute garbage, it has a big melting chamber and is open towards the top, so it would make sense for the steam to escape upwards instead

It's popping a bit as well though, when I'm not feeding a ton of plastic into it

@ChlorideCull oh yikes

Yeah, just wanted to check that you weren’t running it near the boiling point of the PLA

Sounds like that printer is… “fun” 😆

@shyra I've replaced the electronics to get modern features, such as ✨thermal runaway protection✨
