X2 sg2100 motor and dish alignment

I am curious. When moving from a fixed dish to a motorized dish (sg2100), shouldn't the dish alignment be the same when measured after the motor has moved the dish to the correct spot? What I mean is, when setting up a dish for G19, in my area I have an elevation of 46 and a true of 206. When I set up the motor using true south, elevation, declination, etc, and have it turn to G19, it seems to be way off. It should be exactly the same as it was in fixed, right? Or, does it have to do with the way the motor induces the skew angle that will make the angle, as measured from the dish back plate, different?
 
Welcome to Legit tmarkwald! I have a similar setup. I have a 39" ku dish, an sg2100 motor and an X2 receiver. Are you using the USALS option when pointing your dish? Do you have a true south satellite?
 
true south is always the highest elevation in the arc.
The natural motor movement twists the dish downward,lowering the elevation and correcting the skew.
 
Your motor will drive to zero, which is your most southern point. It doesn't necessarily mean it will be at the exact same spot as a particular sat. When aligning a dish manually, using an actuator to move the dish, we concentrate on the closest sat to that-for example my true south sat is Amc 6 at 72w but in reality my true south is about 74w, where my motor will go to zero when using an hh motor.
