kphi is a lua piezo which is having a lot of problems; when it refuses to move, try rebooting the ioc (29idKappa), homing, powecycling, or a combination of all of the above.

Go to grazing ie (th,chi) = (0,90) or (kth,kap) = (57.045,134.756).

Set kphi so that the braid looks as good as possible and the sample plate is along gravity (tab pointing down). If using the scope, remember that the beam comes down at an angle (1.7 deg), so the best is to u.045se the CF10 window with th=90 (sample normal along the beam path).
|
|
|
Once the sample looks aligned, set kphi DIAL to 0; there is a frozen offset between USER and DIAL set to 57.045, so for chi=90 (and only for chi=90), kphi DIAL will be equal to phi pseudo motor.
