Using arduino nano to control table saw adjustments

No, which is what @Paul_KD7HB was getting at.

In basic stepper applications (like a hobby 3D printers) you home them at startup and then count steps and you assume that when you asked for a step, you got one. If your stepper is powerful enough and your mechanicals are ok, perhaps this will work well enough.

If you want to be sure, you need some other way of detecting whether there was movement. Rotary encoders can be used for this.
