I searched around the forum but couldn't find another thread on this.  Is it safe to leave the printer on all the time? 
I'd love to be able to remote in to my computer and print from work so the finished product is waiting for me at home.

That would be your call. Considering some large prints can take more than 12 hours it is hard to not leave on. I have printed 6 years and have all of my printers running over night when I sleep and during the day when I go to work with no issues. However there is a guy over in the Solidoodle section that had his garage destroyed and house totaled from the smoke when his SD caught fire. You have very hot surfaces and materials that can burn if they get hot enough. So it is your call. That one guy over in SD is the first and only report I have ever heard of.
