Your thermistor cable is broken

I bought new thermistors and connected them to the RAMPS board. The temperature reading was inaccurate and the temperatures displayed still move simultaneously. When i connected the actual hot end thermistor the temperature is accurate but the problem persist.

I’d pull the thermistor connector for the HB from the RAMPS board to at least rule out that something funky isn’t going on with the board and/or firmware.

Can you physically feel the printbed warm up?

Yeah I’ve turned the hot bed ‘off’ in the firmware and tested the hot end by itself and the temperature was fairly accurate. Ive also tested the bed by itself and the bed heated up. I just can’t figure out why they are synchronizing.

No I changed it in the Configuration.h file. This problem stated to happen when i changed my power source. Im not sure what happened that caused the problem. Also I have two RAMP boards and the problem persists on both.
