Prior to this section it is expected that sample alignment has been performed (Sample Alignment Quick Reference)
All MEDM windows below should be findable from the main beamline MEDM screen, to bring up this screen double click the desktop icon "26id MEDM" or type "start_epics" on a terminal screen
To process a new value in any MEDM command field the window MUST be selected (left click or double click) and the mouse MUST remain pointed into that field window UNTIL the user hits return
1) Setting up a scan
If necessary call up the scan1 and scan2 windows from the main beamline screen, these are under SCANS-DCM on the bottom left (hit the bottom right more button twice on each)
If saving images from the CCD make sure the change directory triggers are in the before scan and after scan placeholders in the scan1 window (consult with staff if not)
Remove prior positioner by double clicking the drive field until the text is highlighted, backspace, then return
Add a new positioner by middle clicking on the intended motor's command value field, holding the middle button down, dragging to the drive field in the scan window, release middle button, left click, then return
NOTES:
i) Do not use the "Clear positioners" button, this sets the scan type to "absolute" for all positioners
ii) An X next to the drive field should briefly flash if the new positioner is added correctly, and the units field should update
