scan stops during fly scan with a camera time out error #145
Description
The following condition:
- Flat exposure time is set to be different from projection exposure time
- Flat field is taken at the beginning of the scan
- Projection exposure time is much longer than the flat exposure time (2s vs 0.2s)
- The scan has a large number of projections (>3000)
exposes a bug that causes the scan to stop during fly scan with a camera to raise a CameraTimeOut error.
The main issue is that the function set_exposure_time() runs only when the scan is not running but it is also used by functions that are called during the scan with no effect. #144 addresses this issue.
