As an owner of a printer with a 500Watt 240v mains powered silicon heater, no cooking on it has happened yet but with the high power rating and a top rated temperature of 200C it shouldn’t be a problem xD Pancakes anyone?
In my case, not cooking, just keeping my tea warm while I had to calibrate another printer. That and when I arrived home from a ride on motorcylce on a cold rainy day I usually placed my hands on the heated bed for some minutes. I think that counts as a microwaves de-frost option.
You could say that, but it was more like I did not notice that I was out of propane until stove did not turn on… right when I wanted to cook. As for the microwave oven, sh¡t happens as best described by Murphy. Putting it in the printer was a last ditch effort to avoid going out on a cold night. Plus, just why not. Still, the printer is on the high priority list of things that must work for a happy home.
