This options is for the heavier and larger CNC machines. (3) NEMA 34 651 oz-in large stepping motors
(3) Drivers (6.0Amp 24-70 Volts, 1/2-1/256 microstepping)
(1) 36v 8.8a Power Supply
(1) Interface Board depending on the one selected (USB or Parallel)

This bundle would be used in cases where there is one stronger motor needed. In most cases, this larger motor is used to move the gantry as this would be the part of the machine that is heavier or has the most inertia.
