Hi all, I am trying to dynamically change the speed of a slider on a linear rail using a stepper motor (NEMA 17) an Arduino Uno, a motor driver (SN754410) and a 10K Pot. Also, since the rail has a finite length I am trying to have the slider stop right before it reaches the end. I have done my calc…
