The PIGCS2 support uses this approach.

CreateGCSController creates an instance of the appropriate class of

controller based on the controller's version string:

Hi Jörn,

Perhaps what you are asking is if you can define multiple classes:

- Stepper with encoder
- Stepper without encoder
- Piezo with encoder
- Piezo without encoder

I think you should be able to do that using inheritance.  You could create a base axis class that your controller class knows about, but then have the actual axis objects based on derived classes that implement the different types.
