A small tip:

Here are some of the benefits of using a closed-loop stepper drive:

• Improved accuracy: Closed-loop stepper drives can achieve higher levels of accuracy than open-loop stepper drives.
  Reduced missed steps: The encoder feedback allows the drive to compensate for missed steps, ensuring that the motor reaches the desired position.
  Smoother operation: Closed-loop stepper drives can provide smoother operation than open-loop stepper drives, as they can adjust the drive signal to compensate for variations in motor speed.
  Increased torque: Closed-loop stepper drives can allow the motor to operate at higher torque levels by ensuring that the motor is always in the correct position.
