          Hi Hotam,

          You are right, the current design of Thor only uses 7 steppers, so 7 drivers are enough.
          I designed the new board capable to control up to 8 steppers in order to be able to add another degree of freedom. (I was thinking to add rails on the base)

          Hope it helps!
