The closed-loop drive is to feedback the rotation angle of the stepping motor to the control panel, compare the distance that needs to be rotated with the distance of the actual rotation, calculate the error value, and then compensate, so as to prevent the problem of multi-step and lost step. The closed-loop drive can completely overcome the lost step of the open-loop stepping motor, and can also significantly improve the performance of the motor at high speed

Step problem #21

Sometimes the number of steps is more than the set value. Why can this be? This occurs when the printer has not been used for a long time but has been turned on (approximately 30 minutes).
