  • Move the sample in the middle of the FZP: go to alignment tab and move relative X and Z in small steps 0.01-0.1 mm. Click move.
  • Check the alignment of the sample: go to rotation angles 0, 180 and 90 (the sample has to stay in the middle of the FZP at each angle).
  • Go to rotation angle 0 again.
  • Optional: If you need to save a single image, go to Image settings and click “save current image”.
  • Go to alignment tab and click “go to working position”.

“Do you want to move to working position?” will be asked in the pink shell (camera icon). Click in the shell and type Y and enter.

  • Check that the sample is in the middle of the field of view at 0, 180 and 90.
  • Go to Image settings tab and click stop live acquisition!!
  • IMPORTANT : if you wish to go back to the alignment with Pixel Link (paragraph 2), close shutter 2: BS05.2. Otherwise continue with step 4.


  • Go to hzgpp05hama and close HzgDcam.exe
  • Open HCimagelive.
  • Go to Capture and check the exposure time.

  • Go to hzgpp05hama and
  • Click stop and then abort.
  • Close HCimagelive.
  • Start HzgDcam.exe
  • Remember to move your folder from D/hzg/beamtime number to T/current/ raw
