Greetings. The power supply for my TAZ 5 released the magic smoke today. 
I had noticed a “hot” smell for a few minutes and while trying to find the source the power supply gave up the ghost. The PS has been sitting on my desk since I set the printer up on 3/3. After it failed, upon inspection, I notice that 5 of the 6 bosses for the case screws were broke and only one screw was holding it together. After I removed that screw, I see a burnt resister. I assume this to be the problem. See attachment.
Contact support@lulzbot.com and we’ll get you a replacement power supply. Sorry about the inconvenience,
-Jeff
Thanks Jeff. You rock!
So, what exactly is that component? A transient surge suppressor or capacitor?
