I am running Marlin 2 on a Ramps 1.4 and Arduino Mega 2560 kit. I enabled #define pidbedtemp (sorry if spelled wrong), and I set the thermistor 1 (as thermsitor 0 is the hotend) to the 100K Ohm type. I ran D8 to CONTROL IN on my Mosfet (this is what I have if it helps), I ran the 24V DC from my PSU to the Mosfet's DC IN, and I ran the 24V power lines of the heated bed (this is what I got if it helps).
Upon connecting via Pronterface, there is no thermistor reading from the bed. In fact, turning on the bed doesn't seem to do anything besides change the Bed Target line in the temp graph.
I feel like I missed a setting in Marlin or something. I have attached my Marlin Configuration.h file.
