Hello, I have a older version of the Robo R1 and it had the crappy print bed heater with the round cable. The cable kept disconnecting, so they sent me the upgraded print bed heater with the nice ribbon cable. I install and it, but now the temperature sensor is reporting bad values. When I first turn the printer on, it says the print bed is 40 degrees C even though it should be room temperature (20). Any ideas? Thanks in advance.
