I just installed a Lite6 on my Maker Select, making sure to follow the instructions about reflashing the repetier firmware on the melzi board and using tempsensor 8. I didn't get any error messages from the reflash, and made sure to run a PID tune first thing after getting my printer back up and running, but the thermistor is reading about 20º too high. At ambient temperature, immediately after turning the printer on, the bed reads about 20ºC and the hotend reads about 40ºC. I am unable to even print PLA unless the hotend reads about 240ºC, which is much hotter than it should be. My printer has been out of comission for nearly two weeks while I search the entire internet trying to solve this problem, but I'm having no luck at all. I purchased another thermistor, which just arrived today, and I'm having the exact same problem. I never even put this new one in the heater block, just plugged it in and let it sit outside the whole assembly, still reading 40ºC at ambient. Taking it out and measuring the resistance across the molex(?) connector at ambient yields about 115Ω, which goes down if I hold the thermistor itself. What could be causing the problem here? I'd really like to get my printer back up and running.
