Good day sir robin, my overall objective is to monitor the load cell output constantly while the stepper motor turns,
Constantly does not mean the same thing to a computer as it does to a human.
You need to decide what is an acceptable interval between load cell readings - maybe 2 times per second would be sufficient.
Another additions is that the stepper motor we use is a bipolar 4 leads.
That is what I had assumed.
