Hi DavidTaylor,
It's fairly difficult to do coordinated motion in KFLOP by sending low level script commands yourself. That's because coordinated motion normally involves multiple segments that are blended together, trajectory planned, buffered, etc.
Fortunately our Motion Libraries do most of the dirty work for you. But you still must configure the Trajectory Planner, Open the Motion Buffer, define the path (ie StraightFeeds), then trigger the motion (Flush the Motion Buffer). Its a bit more complicated than a single call but very powerful.
See the SimpleCoordMotion C++ project for a simple example.

Actually I now see you asked about C# and .NET. The Process is very similar to the C++ example just slightly different syntax. For C# you can look at the KMotion_dotNet Console example
