this was my understanding/assumption all along. So why do you consider treating it like an axis twisted? It must be synchronized with the planar movement in the same way that a slow tool like a single point threading tool is fed through a piece. It has to be fully coordinated to keep the volume consistently printed. ------------------------------------------------------------------------------ Get 100% visibility into Java/.NET code with AppDynamics Lite!
