SOS: grouping motors #123

Closed cmazzoli closed 7 years ago

cmazzoli commented 7 years ago

@danielballan @tacaswell I would need some help/assistance in defining a set of pseudo motors (or equivalent). Unfortunately, I realized just now that we need this feature implemented in order to progress with the current experiment (beamtime ends monday morning).

The idea is that we have sets of couples of motors (mot1a and mot1b, mot2a and mot2b, ..) and we need to move them as a "package" (the 1s together, the 2s together) in order to mesh them (package 1 against package 2, for example). A relative movement will be indeed sufficient.

How to do it properly? A dedicated plan with outer(inner) suitably nested? I tried sketching something based on ophyd PseudoPositioner but I would like to be sure before making mess and risking the experiment.

Please let me know asap, thanks.

Noting for posterity, this was resolved offline by referring to this documentation: http://nsls-ii.github.io/bluesky/plans.html#multi-dimensional-scans
