14 -* remove vortex
15 -* beamstop to out-position?
16 -* remove goniometer. The airbearing should be stopped (p11/servermotor/eh.1.01)
17 -* move cryojet out of the way, ramp the cryo up and shut it down. Close the compressed air to the shield flow. The biggest cable kinks and needs to be disconnected.
18 -* stop refill of the robot dewar and empty the dewar, warm up.
19 -* Disable backlight (unplug Festo connection). (% style="color: rgb(255,0,0);" %)//Is this still needed?//

This is connected to the leftmost Keithly (power up, check that settings are gain E06, Filter on, Rise time 1 ms.

23 -(% style="color: rgb(0,0,0);" %)Mounting of the TapeDrive is done by the CFEL group. Electronics and control units are combined on a small shelf, that requires only one power and network plug-in. The shelf will be placed left-sided (looking upstream) to the detector tower. The ElveFlow and control laptop as well as several necessary consumables are placed on a cart, which is to be positioned on the right (looking upstream) against the robot platform. The CFEL chiller is placed on the right of the platform and connected to the TapeDrive GASnozzle.
14 +suspension of microcrystals, **at least** 200 µL with 20% crystal density (more is always better), size range: 2-30 µm, **tip:** bring some mother liquor for washing, filtering, diluting etc.

27 -* adjust focus of the tape by moving X in goniometer tower until you see it in the overview camera. Final adjustment should be done when there is flow. Latest value is about 4500 in X and also 5000 in Z (higher soft limit changed from 2976,63 to 6000). (% style="color: rgb(255,0,0);" %)//Better to use the back illumination in the GUI to focus the tape - old instruction, not sure if this is the case. Back illumination is the external light source in the detector tower (the crystallography backlight should be disable for tapedrive).//
28 -* (% style="color: rgb(0,0,0);" %)Check the Minimum Detector Distance; the detector should not collide with the tapedrive while driven to 154 mm but it has to be verified. Also check that all cables and capillaries are taped away when the users start, so that nothing protrudes further than the tapedrive itself. Soft limit can be edited in eh.3.11 Atk panel.
29 -* (% style="color: rgb(0,0,0);" %)Reconfirm the alignment of the beamstop, once everything, including the nozzle, is in place. Modify config.ini for beamstop in- and out-position to both mach in (27 000). This way the beamstop will not be driven out when the hutch is opened, to avoid that the users forget to drive it in when restarting after entering the hutch.
