Has anyone used softmotion with multiple stepper axes?

I'm implementing a multi axes (2 for now) stepper motor control system using cRIO.  I've used the soft motion with a single axis stepper motor before, but I'm unclear on what to duplicate to create a second axis.  I tried copying the spline loop and the stepper control loop, but it would not fit in a 1MGate chassis.  I was led to believe that 5 axes would fit in a 1M Gate system; so, I suspsect I'm doing something wrong.
 
For now, I'm going to just swap out the step and dir io points in the stepper control loop and change which axis is generating the spline data at the RT level.  However, I fear that the internal memory of the spline engine will prevent me from doing this.

Hi Chris,

Have you looked at the example called 3 axis PID (with Spline using FPGA memory).lvproj?  That may help you see how you can get multiple axis set up.  Let me know if that examples helps get you up and running.

Regards,
GG
