Pier flip not working with 10 Micron mount

Last night was the first time I had the opportunity to work with sgp. Everything was working fine with the first sequence image but the start of the 2nd image caused an ascom exception. I am using Per’s driver with a 10 micron mount and have included the log, hopefully in this post. I’ll also post an image of the error message. Thanks for any help.

Ps. Plate solve and autofocus work great with my 12.5" AGO scope. The new autofocus algorithm in SGP was a concern for me, now I just need to fine tune it.
