Stepper current definitely effects how low loud or 'fluid' it's operation is. I tested this today by altering Vref (which affects the current). I actually had to raise to voltage, which in turn raises the current (if i've understood the chip datasheet correctly).

On my printer, only really loud axis seems to be the Y (the arm where the bed is attached to). I was actually wondering if there's something loose on the arm, especially during the fast moves. After rising the Vref from 0.3V to 0.35V the situation improved considerably, the machine doesn't sound like it's breaking apart . I've only done this to the Y axis stepper driver, but it might be that that's the only one i need to alter as other steppers don't sound bad.
