From what I have seen from a while back was to the center of the build plate but others may have it setup differently.
The motion of the arms is what will determine the build shape of the base of the build area volume a 1:2 was said to get you the optimum build size and as you veer away from it it will change the shape to a more triangular shape reducing the build volume. This should be the only casualty print quality should not be affected.
