77 +The TapeDrive is controlled through kamzik. To open kamzik, start the server. A terminal will open, shortly after a small window.
78 +Now start the client. Same thing, a terminal will open, shortly after a small window.
79 +
80 +Click 'Devices' in the **client session** to open the control window.

83 +* **Tape:**
84 +** Click on the 'main tape' icon
85 +** Change the velocity by typing anything from **0.3-3.0 mm/s**
86 +** Common velocity is 1.0-1.5 mm/s
87 +** kamzik displays the used tape in m and %. At 98% the tape will automatically stop since the rolls need to be exchanged at this point.

92 +* **Sample nozzle:**
93 +** Click an the 'nozzle' icon.

95 +The nozzle position can be adjusted in xyz by clicking on the arrows up and down. Step size can be varied, 1mm steps are rather big and should be used carefully, for y-movement always use a stepsize <= 0.5mm.
96 +The absolute position is **not calibrated** and therefore changes after each restart of kamzik.
97 +\\Adjust the nozzle position visually until it nearly touches the tape and roughly meets the X-ray interaction point. Then, move to the control hutch to use the on-axis microscope for fine adjustment. Move the nozzle tip to the X-ray beam (red X) and write down the absolut nozzle position. From there move the nozzle in +x to your desired distance.
