The condition you describe is one of several situations where autofocus gets off the "sweet spot", then struggles to recover (potentially impacting scheduling). This is exactly why I've suggested we need to think about temperature and elevation focus compensation to improve starting seed position for the autofocus loop. Just remembering the last successful position won't work for several situations. I don't want to hijack this thread; I'll just note another topic for those interested. Cheers, Doug
