It is quite impossible to get all values adjusted to extactly the same.
I would test it for a longer print and if the motors get hot just turn the pot down a tiny bit.
I know that my steppor motors are extremely noisy at those levels. Mine right now are at .3, but that's for a delta printer with pretty tight belts. I like to decrease it until the motor skips, and then adjust like .05 volts or so.
