astrosatch If telescope is autoguiding on the west side of meridian, when I slew to east side, calibration data is not automatically flipped and autoguiding goes haywire.
This is correct behavior.
Only a GOTO command to the mount will cause a mount to perform a Meridian Flip. A slew command will not.
This is how the ASIAIR causes the mount to perform a Meridian Flip (what ZWO calls an "Automatic Meridian Flip") by sending a GOTO command at the proper time.
You can check this out on your mount's controller. You can slew anywhere you want (usually a warning that you are slewing too close to the Sun), including across the Meridian. Only a GOTO from the hand controller will perform a Meridian Flip, if the pier side demands it.
