Hey guys, when ever i start my print, my heated bed will heat up along with my nozzel, then it proceeds to print. But after the print the heated bed will stay heated and it wont cool. Not using mosfet. Have an external power source going into the 11a in my ramps 1.4. Tried using m140 s0 for the bed and it didnt work. On my display it shows the bed temp followed by /0.

If the bed doesn’t start cooling off after it says /0, you likely have a bad board and have to replace it.
