Hi Torsten,

Look at this database:

https://github.com/epics-modules/motor/blob/master/motorApp/Db/sumDiff2D.db

You load 2 of these for a 4 blade slit.

We use this for lots of systems where you want to move 2 motors in the same direction and opposite directions. For example 2 moment mirror bender, slit,
Etc.

Hej motorists,

I recently learned about the transform record,
which can be used to control a slit with 2 physical
axes in the way that you can set the values for GAP and
CENTER and the position of the physical blades are
calculated. (Or vice versa)

Does anybody have a super-duper-luxus template file
which uses 4 soft motors together with some calc
and transform records ?

Thanks in advance
