Gday Steve
If you are just trying to do an autoalign, SmartMount (SMT) doesnt come into it.
If the scope can get a GPS fix, and also slews OK to find home and north, then slews down and crashes the OTA into the base, thats normally indicative of a failed level sensor
or a broken cable in the left fork arm.
Open the left fork arm cover and look at the sensor bolted to the axle.
As you move the tube up/dn, you should see a little ball rolling in a plastic cage. If that is free, then look at the wires in the heavy grey ribbon cable going from the lower circuit board to the level sensor board.
If this is stuck/cable tied to the axle, the constant flexing causes wires to break internally at the flex points. Feel the cables and if you can, use a multimeter to test for continuity.
If this is the case, you can still use the scope in manual 2 star mode
till you get it fixed.
