FYI, thermistor failed, found set screw was way too tight.
Had the thermistor fail yesterday, luckily after finishing up a print job. Prusa support was awesome with a quick troubleshoot and sending a replacement. Today I pulled out the factory installed thermistor and found the set screw was super tight and had actually smashed the end of it. It's my understanding the set screw should only be barely over finger tight. Threw a spare in and back to printing. Just an FYI and otherwise LOVE this printer!
