How to get a list motor angles into an Arduino to drive a motor

groundFungus:
We need to know exactly what motors, drivers and Arduino board you have.

How is everything powered (motor power supply and Arduino power supply).

How many values are there? What are their data types? Will the data change while the code is executing?

Sorry that's my bad. I believe we have:
An Arduino Uno
Two 3540M Stepper Drives
Two Lin Engineering W0-416-05-04 Motors

We are using a power supply for the motors and just plugging the ardunio into a computer I think?

There are roughly 300 values, they should just be floats. The data won't change as the code is executing, we have generated all the angles we need and now want the motors to step through each angle.

Thanks again and sorry for the confusion!
