Motor Speed Definition Not Working

[calvinred]

We have defined a motor speed for our talons controlling our lift motors (it is set to 1.0). How it is supposed to work is that when we press a button on our joystick, the motors will go at the speed we tell it too, the problem being that it doesn't. It gives a speed closer to .3 or .4. However, when we hook it up to a battery alone it goes at a speed of 1.0, or when we mess with our wiring so our drivetrain joysticks control those motors (this also puts the motors at 1.0). What could be causing this? Has anyone else dealt with this?
