If you're on the fence about building or buying a 3d printer enclosure, please let me give you a push.
(sh.itjust.works)
I should have built this thing from the word go. I ran this printer for almost a year on my desk right next to my computer. But it was loud and smelly and the high traffic area played havoc on print quality and caused a lot of warping.
Now that it's tucked away in a back room suspended in a corner by French cleats and sitting directly on top of dense foam and a big ass paver it is merely "audible" but certainly ignorable. There's also no more headaches from the smell, and my print quality has never been better.
Do yourself and your printer a favor and get an enclosure sorted out asap.
Bit of a, bit of b, thermal protection on printers sets a minimum hotend and bed temperature, it's configurable but 0c is pretty common. Drop below that and the firmware will trip an emergency shutdown in klipper, some (mk3s) set off an alarm beeper when that happens.
Higher ambient helps with chamber temps too depending on what you print. I let my printers heat soak for at least an hour before I print anyhow, the space heater gives some stability in ambient temps.
Also done prints where I've just blasted the hotend and build plate with a heatgun to get above the min temps to be able to get a heat soak going. Vorons have a decently powerful bed heater (~600w if I recall), my mk3s isn't nearly as powerful but still capable of sustaining itself (would definitely benefit from insulation)
