Printer stucked at heating.

[MR.Potato]

Hello!

Last week i bought my first 3d printer ( GEEETECH Prusa I3 B ) .
To this day everything was working fine. Last night i fixed my last problem and printed my first print ( fan holder ). BUT...today i came home from work and i was ready for my next print. So i generated my G code and start printing. Unfortunately my extruder and heatbed wont to heat up. Repitier - H shows that they are both "off". I can heat them manually and everything seems fine. They reach the set temperature and hold it. So i tried to unplug and plug everything, reupload firmware but nothing helped. Anyway if i heat it manually and then start the print it seems fine but it seems like the extruder is little bit confused and not pushing enough plastic.
Here are the first 22 lines of the G code :

M107
M190 P65 ; set bed temperature
M104 P220 ; set temperature
G28 ; home all axes
G1 Z5 F5000 ; lift nozzle

M109 P220 ; wait for temperature to be reached
G21 ; set units to millimeters
G90 ; use absolute coordinates
G1 Z0.300 F6000.000
G1 A-2.00000 F2400.00000
G92 A0
G1 X57.829 Y17.308 F6000.000

Thank you very much!

I forgot to mention that if i try to print from SD card same problem will occur. Lcd says "Heating...." but extruder temp. is 27/0 same for the heatbed. Si i believe that there is some kind of problem in communication.

UPTADE:

I find out that the gcode which I was using first works fine. So there is probably something wrong with the G code generator. I´m using slic3r version 1.2.9.
Or could it be a problem with the .stl filed which I´m using?

SOLVED

I accidentally changed the code type unnoticed to "Machinekit"

LOCK or delete please.
