Repetier firmware - Extruder motor not responding

Hi,
I'm new to 3d printing and I just finished building my prusa i2.
I bought megatronics v2 electronics from reprapworld.
I tried to use marlin firmware as recomended but I couldnt connect with pronterface.. so I switched to repetier host and firmware
I managed to connect with the printer and manualy move X Y Z axis, but for some reason I cant control Extruder motor..
I did connect the motor cable into the E0 slot and pluged the stepstick into the corresponding slot..
I tried to connect the E motor to the X axis and it worked just fine.. so the problem isn't at the cable neither the motor..
I switched the stepsticks and nothing changed.. so I believe I am doing something wrong at the firmware configuration..
What I should check?

I included my configuration.h

Elias,

Check pins.h, just to be sure:

#if MOTHERBOARD == 701
...
#define E0_STEP_PIN        35
#define E0_DIR_PIN         36
#define E0_ENABLE_PIN      34

Thanks for the answer.. I fixed it some days ago.. It needed to heat the extruder first..

Ok, Did you change the Configuration.h file above?

I saw your setting MIN_EXTRUDER_TEMP = 0, so it should work with a cold extruder too.

/* \brief Minimum temperature for extruder operation

This is a saftey value. If your extruder temperature is below this temperature, no
extruder steps are executed. This is to prevent your extruder to move unless the fiament
is at least molten. After havong some complains that the extruder does not work, I leave
it 0 as default.
*/

#define MIN_EXTRUDER_TEMP 0

I changed the pins in the extruder heater (pins.h) and after the heater worked .. I was able to move the motor...

This fixed a problem I have. Understanding the program and the willingness to share is a great thing, thanks
