Thanks everybody for the fast answers-
I think I was looking for "2slit_soft.vdb, which uses soft motor records,
instead of ao records, for center and width."
The good news: I got it working!
There is one question about the collision avoidance:
If the Gap is 0 and the slit is closed, and I move the center
there seems to be the risk for a collision, or better said,
that one blade is slightly started earlier and "pusshing" the other
one. I am not sure if this is a real-life problem.
The other thing is that I need to check the calculation of the
soft limits for the virtual motors.
The most obvious is that the rule "Gap > 0" is not there.
(And the other calculations need to be checked)
I'll set up a system with a simulator.
And of course, we are setting up a system as well,
where the synchronization is done in the motor controller.

Hi Torsten,
The synApps optics module has support for this type of thing:

Subject: Controling a slit system with 2 hard and 4 soft motorrs
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
