Auto Focus hangs when taking images

Hello,

I’ve run into an issue where the auto focus routine fails to take images. The graph appears and the countdown starts, but the camera does not respond. If i manually abort the focus sequence, the sequence moves onto light frames and the camera operates as expected. The key lines appear to be:

…and the link to the log file is:

As you can see, everything works as it should until the auto focus camera command fails. Any ideas on how to solve this would be most welcome, and I will be happy to post any additional information as necessary. Thank you!
