finally got the cube installed but I can't get the drawtube to go back to the point where focus would end up being! Is there a way to get the Cube to move out further?

The only thing I found was change the Absolute to like 100000 but then the motor continues to try to move forward and that would give me enough steps to move it back but I worry that since it reaches max inward movement at around step 9000.

Thanks
Jeff
