I'm very new to 3D printing, and not sure what caused my Thermistor wires to break.. I was building a 3D rendering of a prototype I designed (pretty simple rectangle shape), put it on high quality (.1mm layers), and came down to check on it a couple hours later, and the hot end was stuck in the plastic. Then once I couldn't heat the bed or hot end, I troubleshooted, and saw the wire was disconnected. So I have two questions: What could have caused this to happen so I can learn and prevent it in the future? I've searched this forum/google for the past hour, and can't really seem to find a plain old Thermistor replacement. Any suggestions? Really hope I'm not repeating a post that's elsewhere..
