IMPORTANT - this tool will +command the stepper motor to move without checking the normal +kinematic boundary limits. Ideally the motor should be disconnected +from any printer carriage before performing calibration. If the +stepper can not be disconnected from the printer, make sure the +carriage is near the center of its rail before starting calibration. +(The stepper motor may move forwards or backwards two full rotations +during this test.) After completing this test use the `SAVE_CONFIG` +command to save the calibration data to the config file.
