Without going into great details. I will show you what my stepper settings are.
X, Y, E0 and E1 are all 0.695 on my 12 volt 3D Printer
X, Y, E0 and E1 are all 0.395 on my 24 volt 3D Printer
Now the dual Z axis is 1.396 on my 12 volt 3D Printer this is almost exactly double, being only 0.006 volt differences.
And the dual Z axis is 0.710 on my 24 volt 3D Printer this is almost exactly double, being only 0.080 volt differences.
Just double the Vref two steppers twice the vref current.
vref = (current * 8 * 0.11) * two steppers
vref = (current * 8 * 0.11) * 2
This current can vary slightly.
