Mini. Kappa: repeatability move to reference, move to position CONFUSION! re-initialize move around, come back off by ~3º back within <0. 05º When motors are driven from the MD 2 Kappa motor phi tuning box using default “motor” coordinate system, the backlash and relaxation corrections are not applied. (Positioning is not repeatable) When driven from the device server or in any other way using the “device” coordinate system the corrections are applied, but the position is not updated during the backlash correction – so it looks like it is not applied. kappa (Positioning is repeatable) Device is OK, control via STAC is OK 24/11/2009 Gleb Bourenkov Meeting Bilateral GR-HH Instrumentation
