Controlling 4 stepper motors for 3D printer using my-rio FPGA

[Kashish]

Hello,

I have a project to control 4 stepper motors for a 4 axis 3D printer. I know using soft-motion one can control the motors by defining the axes. But I want to use my-Rio for this purpose. I am not sure that my-rio can handle all 4 axes. With my-rio, it gives me two options either simulated axis or unbound axis. I don't know what is unbound axis and how to assign particular DI/O pin to each axis? I saw many examples for c-rio but it doesn't explain which pin is corresponding to which axis. If I knew how to assign pins to motor then I would be able to assign my-rio DI/O pins to the example code.

Can somebody help me out with this problem?

I think this is partially solved in thread

Kashish, let me know if the examples worked, please.
