When my sg6100 runs back to 0 the lcd goes to all dashes and it runs all the way to its limit. Unhooking the coax and doing a reset at 0 it works fine til I cross 0 again. Thought it might be my receiver but got my new MicroHD today and same thing happens. Guess I got a faulty motor. I wonder if I disabled the microswitch at 0 if my problems would go away... Anyone else have this motor and have same issue?
