heated bed heats indefinitely

While using manual control the heated bed and extruder heat only to the temperature I tell them to. After slicing an object and hitting print, the bed heats up to the desired temp, 55 c, and just keeps going past till I get an error message around 115 degrees.

It does not matter if I type in a different value for the bed temp or use the temp slider to change it, the bed continues to heat.

My setup: Prusa i3, Repetier host, Arduino Mega w/ ramps

Did you check the MOSfet area on RAMPS for bad solder jobs and the like?

What if you pause the print, change temp, wait and resume?

strange that it works ok manually, can you post the 1st 50 lines of your sliced G-code.

Here's the first 50 lines

M190 S115 ; set bed temperature and wait for it to be reached


This is trying to heat the bed to 115 C and is probably timing out,giving the error.
