Douglas,Writing an asyn model 3 driver for the Ensemble is still on the to-do list. If you need to do it, I would suggest using the profileMove functionality of the model 3 Newport XPS driver (XPS{Controller,Axis}.cpp) as an example.
We are doing multi-axis coordinated motion with Aertoech Ensemble controllers at the APS using the SNL trajectory scan program for the Ensemble, but the synchronization of the axes is less than ideal, since a channel-access put is starting the motion for each axis.
My understanding is that multiple ensemble controllers can be daisy-chained and configured to do true synchronized moves (using Aeronet), but the downside of this approach is that the individual axes can no longer be moved independently, which is undesirable for us.

Hello,here at LNLS, we are using the asyn model 2 driver of the epics motor to control a ensemble controller (Aerotech) that move two linear stages and a goniometer stage, but we would like move two motors (linear stages) simultaneously, and we saw that this is not possible using this asyn model driver.In this presentation about coordinated motion: https://www.synchrotron-soleil.fr/fr/file/8469/download?token=x3GbKcgtMark mentions as a future work convert Aerotech Ensemble to asyn model 3, I would like if anyone has a update about this or are using coordinated motion with ensemble controller?And, if we need to convert to asyn model 3 for this controller, what is the best way or examples to follow?Many thanks, -- Douglas Henrique C. de Araujo Software de Operação das Linhas de Luz Laboratório Nacional de Luz Síncrotron – (LNLS) Centro Nacional de Pesquisa em Energia e Materiais (CNPEM) [email protected] | +55 (19) 3512 1228 www.lnls.br
