Wow, those temperatures are really high. Does the bed even get that hot by default?

No, it stalls at between 105 and 120 depending on the individual printer. He has added a extra silicone heater to the bottom of the bed to boost the temperature.

I posted asking about fumes. I know some high temp stuff really requires some respiratory safety
