extracting trajectory data as a function of time.

[payz]

Hi, I am a new Labview user. I am trying to write a simple code in Labview 8.6 to control a stepper motor and do some profiling with a probe which is being moved by the motor. So far I have been able to control the motor but I cannot get the motion data while to motor is moving. For instance I need to know how many steps the motor has moved at a desired frequency while the probe is giving data at the same frequency. Can anybody help me please? 

To make it clear I wanna plot the probe data as a function of position. So I need to know how many steps the motor has moved at each time also what value the probe is giving me at that particular time.

Thanks a lot

Payz,

What hardware are you using?  Do you have an encoder connected to get feedback from you stepper motor?  As well which motor are you using?
