Marlin firmware fork for MakerFarm i3v w/ auto bed level & Roxy's enhancements

The Thermal Parameters are (in my opinion) overly tight. The people that wrote the Thermal Protection wanted to make them even tighter! I have mine currently at these numbers, but I think I'm going to have to bump the 20 up to 30.

#if ENABLED(THERMAL_PROTECTION_BED)
  #define THERMAL_PROTECTION_BED_PERIOD 20    // Seconds
  #define THERMAL_PROTECTION_BED_HYSTERESIS 2 // Degrees Celsius


  #define WATCH_BED_TEMP_PERIOD 60                // Seconds
  #define WATCH_BED_TEMP_INCREASE 2               // Degrees Celsius
#endif

Hi

A heated bed is a much different animal than a hot end. The numbers you need for one are not what you need for the other. A bed isn't going to kill it's self in a minute or three. A hot end easily could get into big trouble in that amount of time. ....
