my 3D printer does not print

i have a ord bot printer and when i check my x,y,z axis and extruder are working ok but when i am going to print it doesn't do anything.even the temperature does not change.
i use the pronterface programm. can you help me?

Can the post the gcode file for the print

this is the code.

The second command is

"M190 S55 ; wait for bed temperature to be reached"

This set the heated bed to 55c and wait for the tempature to be reached before accepting any more commands.

If your bed is not heating or the bed thirmistor is not reading the bed temperature it will sit there forever on this command.

remove this line from the gcode (its just a text file) to check this is the problem. (ie it wont heat up the bed, so expect the print to fail, but it should go threw the motions

I agree with Dust, but,

You say the temperature is not changing, has the heat bed heated up before? If not check the wiring for the head bed and associated thermister

did u wiring your heat head correctly and enable your D10 port ?

thank you very much. i deleted this line and my printer is working now.
i don't use heat bed..
