hi,
I post this issue about the autofocus system. It was working properly and suddenly the last two sessions the autofocus began well but when it continues doing the curve appears a peak and the autofocus fails. I attached a video that it can be see it better:

And here the log of autofocus:
If someone can tell why occurs this “peak” it would be great.
Thanks
It’s failing because the quality of the quadratic fit is too low. You may be able to correct it with settings (like a larger backlash compensation), but ultimately you can decide what quality is good for you. See this post for instructions on how to change it (not that you can add this variable to your equipment profile too):
it’s possible too that you are taking readings over too-wide a range. At one point, you had 99% fit.
