Thanks Kevin.

I’ve got those records but I’m not clear on what you mean.  None of those PVs appear to set a wavetable entry.  Are you saying that the current implementation only allows keeping the wavetable in the outside program and issuing a series of moves by setting the val motor field, waiting, and setting the next?  So not using the ability of the nPoint to do custom wavetables at all?  Is loading a custom wavetable what you mean by profileMove isn’t implemented?

There is a driver in the synApps motor modules and the documentation talks a lot about controlling the stepping through the wavetable but I can’t figure out what PVs I’m supposed to use to set the wavetable values.
