Repeatable different steps of a stepper motor

Question

Hello everyone,
I am working on a project where i have a stepper motor moving a plate and a signal sensor who measures a distance. I managed to initialize the signal so my initial position is the position where the sensor gives me the minimum value (Voltage).Each time the stepper motor moves, i define it from the front panel. My question is, how can my stepper motor moves automatically for e.g. 8000steps then without define it again for another 5000 steps or whatever i want with a time delay. The definition of the steps now is being done from DAQmx Timing>Samples per channel. I want to run the program and the steps to be already defined wihtout change them again and again from the front panel. I attach my current VI.
Thank you in advance

Hi Chris,
not a problem, we all were new at some point. In case you don't know there are boatloads of classes you can access online with your License or even without one:
Here's a small collection (courtesy of crossrulz):

And if you are a student you can take a real class with NI for a ridiculously small amount of money (say, 93%) discount).
With start twice I mean that I was wrong in believing you did so, when I fact you started two different tasks, so: nevermind.
PFI stands for Programmable Function Input, which is confusing because it is probably assigned to an I/O line. I just asked to find out what section of your code I have to look at. I'm still not quite sure about this, butI understood you want to move the motor, when you push a button. The only part of your code, where you even read a button within a while loop is for the Direction Line. Apart from that you just write the inputs once and then forget about the tasks (not even stopping them sometimes). I suggest moving the button that should move the motor into a while loop.
