Not from my experience. It usually has to do with how the plugins work with macros. For instance, most chinese controllers do not support Mach3's GetVAR()function, which is usually used to find the trip point.

Most plugins don't really on any specific DRO's.

DRO conflicts between wizards and screens is a different issue, imo.
