I just received the above mount purchased new. The red power light comes on and the hand controller works. However when I press any of the direction keys the mount will not move in either axis. I am using a high-quality regulated power supply. The hand controller goes through the 'process' of alignment but the mount never moves. I have a light-weight, Red Cat 51 scope on the mount and it is properly balanced. I cannot hear any noises from the mount. Clutches are tightened fully. Can anyone offer any advice on this?
