I'm having a problem with my Heat bed, does any one know anything about the new updated Marlin firm ware, checked all the setting and it's not working get to 71 C and "bed Heating Failed" whats up? not sure even what lines to copy to look at anymore.
I have a Reprap Prusa i3 Mandel , 270x220x180mm, the hot end is a All Metal J-head Hotend for 1.75 mm Bowden Extruder
Ramps 1.4 Marlin 1.1.9 firmware.

--NORMAL IS 4.7kohm PULLUP!-- 1kohm pullup can be used on hotend sensor, using correct resistor and table
Temperature sensors available:
-4 : thermocouple with AD8495
-3 : thermocouple with MAX31855 (only for sensor 0)
-2 : thermocouple with MAX6675 (only for sensor 0)
-1 : thermocouple with AD595
0 : not used
1 : 100k thermistor - best choice for EPCOS 100k (4.7k pullup)
2 : 200k thermistor - ATC Semitec 204GT-2 (4.7k pullup)
3 : Mendel-parts thermistor (4.7k pullup)
4 : 10k thermistor !! do not use it for a hotend. It gives bad resolution at high temp. !!
5 : 100K thermistor - ATC Semitec 104GT-2/104NT-4-R025H42G (Used in ParCan & J-Head) (4.7k pullup)
501 : 100K Zonestar (Tronxy X3A) Thermistor
6 : 100k EPCOS - Not as accurate as table 1 (created using a fluke thermocouple) (4.7k pullup)
7 : 100k Honeywell thermistor 135-104LAG-J01 (4.7k pullup)
71 : 100k Honeywell thermistor 135-104LAF-J01 (4.7k pullup)
8 : 100k 0603 SMD Vishay NTCS0603E3104FXT (4.7k pullup)

12 : 100k 0603 SMD Vishay NTCS0603E3104FXT (4.7k pullup) (calibrated for Makibox hot bed)
13 : 100k Hisens 3950 1% up to 300°C for hotend "Simple ONE " & "Hotend "All In ONE"
15 : 100k thermistor calibration for JGAurora A5 hotend

75 : 100k Generic Silicon Heat Pad with NTC 100K MGB18-104F39050L32 thermistor
1k ohm pullup tables - This is atypical, and requires changing out the 4.7k pullup for 1k.
(but gives greater accuracy and more stable PID)

52 : 200k thermistor - ATC Semitec 204GT-2 (1k pullup)

PID Bed Heating
If this option is enabled set PID constants below.
If this option is disabled, bang-bang will be used and BED_LIMIT_SWITCHING will enable hysteresis.
The PID frequency will be the same as the extruder PWM.
If PID_dT is the default, and correct for the hardware/configuration, that means 7.689Hz,
which is fine for driving a square wave into a resistive load and does not significantly
impact FET heating. This also works fine on a Fotek SSR-10DA Solid State Relay into a 250W
heater. If your configuration is significantly different than this and you don't understand
the issues involved, don't use bed PID until someone else verifies that your hardware works.
