(Beta 13, PHD2 2.4.1.g) My sequence did not start up correctly and went into recovery mode - I shall dig out the log files to look into it. That may result in another post.
Anyway, I aborted the recovery mode (after some time) and got PHD to calibrate and ran autofocus with my Lum filter.
In my autofocus settings, I have AF enabled for before sequence start but not for resume. I hit Resume on the Sequencer window and it started to autofocus. That suggests that either, this is not a true resume (as the sequence never got off the ground) and the button is wrongly labelled, or the AF trigger is not reading the run sequence / resume sequence status correctly.
When I’m done for the night I will recovery the log files and post them if you need them.
