Re: Beware your 3D printer (They can cause fires)
That's awful, Skyminer. I ran two Solidoodle 3s around the clock for three months in my garage for my Kickstarter "Pinhole Printed" and I was constantly worried about that possibility. I set up a Dropcam to watch the printers if I had to be away and WeMo switches to remotely kill the power, and a Nest smoke detector overhead to let me know at work if it went off - and I still worried I couldn't stop it in time.
Unfortunately, many things require more than 8-10 hours of printing time and there's no choice but to leave it running unattended some of the time. The analogy to leaving the kitchen with a pot boiling is just not a good one.
In a perfect world, we'd have a metal shed with AC and power in the backyard just to run our printers. More fail safes are an excellent idea and we'll just have to get used to the extra cost.
