I started a scan with MF and 3/5 stacks. After about 60 pictures, the scan suddenly stopped. (IMX519 )
The logs didnt give any information. After about 10 minutes, it was just said that the device is not connected anymore.
Neither a reboot (software) nor reset on the device itself helped. The scan was still not cancelable.
In addition, the stacks weren placed evenly within the focus range which set from 7.5 - 9.5.
It took 3 pictures but 2 of them with the same focus setting.
I also posted this in the openscan3 discord channel.
Greetings and thanks for your work!
