The idle current reduction is just to reduce the heat in the motors (save wasted energy) because steppers require less holding current (torque) than they require driving current (torque).
Stiction occurs mainly with heavy machinery incorporating cast iron way and gibs etc but there are lubricants available these days that can reduce that effect to a bare minimum if you have sliding bearing surfaces rather than ball or roller types.
What voltage are you running the steppers at 24V ? and have you increased the drive current ?
Tweakie.
