Changes

  • Separated fast_autofocus API route from up_down_up_autofocus
  • Reverted default /fast_autofocus API behaviour to simpler fast_autofocus method
    • Our main use case for fast_autofocus on the project is scanning thin blood smear images with a 100x objective. In these cases, the up_down_up_autofocus method has been unreliable. For this release we’re (trialing) reverting to the simpler fast_autofocus. It’s a bit slower (previously ~ 4 seconds, now ~ 6 seconds), but it seems much more reliable.
  • [GUI] Fixed duplicated mini previews in settings
  • Add interface to change stage geometry
  • Added an API route to move while measuring sharpness
  • Major code cleanup
  • Proper PyLint configuration
  • Minor graphical interface layout fixes
  • Upgraded to LabThings 1.1.1
    • Fixes failed ZIP downloads
    • Fixes occasional scan failure
