There is also a calibration object that includes all planes in one model. You want the object oriented so that corner A is toward the origin of the plane.

"Webb[skew_correction]¶ Printer Skew Correction. It is possible to use software to correct printer skew across 3 planes, xy, xz, yz. This is done by printing a calibration model along a plane and measuring three lengths. Due to the nature of skew correction these lengths are set via gcode. See Skew Correction and Command Reference for details. " - Simplec算法的skewness correction
