Final problem on dual extruder

I have Finally completed my dual extruder and uploaded an operational firmware, but there is one final [major] problem.

Everything is fine before I print. I click print and it homes, but I wait and wait and the print never begins. Not sure what info would be needed to solve this, but ask and I shall tell anything about it.

Does the temperature drop when it positions and moves ready to print?

I used to have that problem, the firmware was waiting for proper printing temp, but it was hard to reach so it was just waiting for the correct temp.
