I am trying to control a stepper motor using a LabVIEW VI(see below), an Arduino Uno, and an Adafruit Motor shield. This is the motor I am currently using https://ozrobotics.com/shop/nema-17-stepper-motor-bipolar-l33mm-with-gear-ratio-271-planetary-gearbo... which has a step angle of 0.067 degrees. I am trying to create a while loop that moves the motor a total of 6 degrees over 32 iterations, so each angle step is 6/32 or 0.1875 degrees. While the motor does move, when we use larger angular increments, the angle to which it rotates is noticeably incorrect. As for the 0.1875-degree increment that we need, the motor does not move at all. The planetary gear degree and the rotational stage gear ratio were taken into consideration so I am not sure what else to do to fix this. Any help or suggestions would be appreciated. Thank you.
