It appears that SGP does not have a timer for opening a Flip Flat prior to solving at the start of a run am i missing something?
To solve this (in theory not had chance to try it yet) I assigned my plate solve to filter slot 8 to force a filter change as I never use this slot, (its empty) and added a 10 second filter settle delay, this allows time for the Flip Flat to open fully.
I can’t recall what order things happen in but if the flip flat opens first then this should work. You could also put in a 10 second flat right before your other flats which would also work.
I’ll adjust the code for the flip flat itself to block on shutter opening/closing if possible, if not I’ll just add a static delay of say 10 seconds. I’ll likely need one of you to check this for me as I don’t have a flip flat to test with (I would love one but it won’t fit in my VERY tight dome 
). I’ll try to get a test build out in a couple of days or get this into the next RC/Beta.
Thanks,

Ill be more than willing to test it for you 
Thinking about it it might be worth been able to input custom Delay operation into anything, rather than just looking at the flip flat?
Edit (delay not pause)
I think this may be down to a timing issue. I believe I’ve resolved it. Should be out in the next RC which will be coming shortly.
Thanks,
Jared
Due to ongoing technically issues wich i have only recently got resolved I have yet to lok into this specifically, I will be over the next few clear nights at last.
it worked.
