The fourth step: click confirm again after download the test cut files, repeat the
first step to the third step operation, once again try to cut the calibration work, until
the test cut calibration trajectory and print trajectory exactly the same sensor
calibration work is completed, the accuracy of shadow sensor calibration ring
following cutting accuracy.
Note: in order to obtain a higher accuracy of the cutting trajectory, it is
recommended to adopt method 1 for fine positioning and calibration
