It sounds (pardon) like your problem may be that the motors are stalled.
They are not powerful enough to move the load. Try to run the motors without the screws connected. Threaded rod will suck up at least 60% of the torque, more if you have any anti-backlash setup. This is just a guess, I know too little about your setup to do better than guessing.
If they are stalled you can still hear that they try to make steps. You may even be able to feel it if you put a finger on the shaft. (Don't try that with bigger motors! You might need the finger later.)
