Ramps 1.4 marlin heated bed options doesn't exist.

Hi guys, so before i smash my printer i thought il ask for some help. i recently fitted ramps 1.4 onto an anet A8 and ive been going through the setup getting the steps right and the directions but im stuck at getting the bed to heat up and the fans to turn on
Ive tried setting the fan pins to every possible number but they just dont work, also the menu on the display seems to not have bed heating options or temps. what is going on ?

Did you set up Marlin to use a heated bed in the firmware?

What version of Marlin are you using? 1.1.9 or maybe 2.x?

The marlin i downloaded a couple of days ago only says marlin 1.1.x, i cant find any other reference to the version in the files or website, as for enabling the bed, tere are no options im my config. did marlin mabe put a dud on their website ?

you enable the bed by defining a bed thermistor

find the section that looks like the following in Configuration.h

#define TEMP_SENSOR_0 1
#define TEMP_SENSOR_1 0
#define TEMP_SENSOR_2 0
#define TEMP_SENSOR_3 0
#define TEMP_SENSOR_4 0
#define TEMP_SENSOR_BED 0
#define TEMP_SENSOR_CHAMBER 0

change the number after TEMP_SENSOR_BED to match your thermistor type

as for fans, the ramps only has one fan mosfet on D9

This is automatically configured when you set MOTHERBOARD BOARD_RAMPS_14_EFB

The fan does have polarity, it will only work one way. also many fans don't work at low speeds.
use M106 S255 for full on and M107 to turn the fan off.
