+ * Bed Skew Compensation
+ *
+ * This feature corrects for misalignment in the XYZ axes.
+ *
+ * Take the following steps to get the bed skew in the XY plane:
+ *  1. Print a test square (e.g., https://www.thingiverse.com/thing:2563185)
+ *  2. For XY_DIAG_AC measure the diagonal A to C
+ *  3. For XY_DIAG_BD measure the diagonal B to D
+ *  4. For XY_SIDE_AD measure the edge A to D
+ *
+ * Marlin automatically computes skew factors from these measurements.
+ * Skew factors may also be computed and set manually:
+ *
+ *  - Compute AB     : SQRT(2*AC*AC+2*BD*BD-4*AD*AD)/2
+ *  - XY_SKEW_FACTOR : TAN(PI/2-ACOS((AC*AC-AB*AB-AD*AD)/(2*AB*AD)))
+ *
+ * If desired, follow the same procedure for XZ and YZ.
+ * Use these diagrams for reference:

+ * Bed Skew Compensation
+ *
+ * This feature corrects for misalignment in the XYZ axes.
+ *
+ * Take the following steps to get the bed skew in the XY plane:
+ *  1. Print a test square (e.g., https://www.thingiverse.com/thing:2563185)
+ *  2. For XY_DIAG_AC measure the diagonal A to C
+ *  3. For XY_DIAG_BD measure the diagonal B to D
+ *  4. For XY_SIDE_AD measure the edge A to D
+ *
+ * Marlin automatically computes skew factors from these measurements.
+ * Skew factors may also be computed and set manually:
+ *
+ *  - Compute AB     : SQRT(2*AC*AC+2*BD*BD-4*AD*AD)/2
+ *  - XY_SKEW_FACTOR : TAN(PI/2-ACOS((AC*AC-AB*AB-AD*AD)/(2*AB*AD)))
+ *
+ * If desired, follow the same procedure for XZ and YZ.
+ * Use these diagrams for reference:

+ * Bed Skew Compensation
+ *
+ * This feature corrects for misalignment in the XYZ axes.
+ *
+ * Take the following steps to get the bed skew in the XY plane:
+ *  1. Print a test square (e.g., https://www.thingiverse.com/thing:2563185)
+ *  2. For XY_DIAG_AC measure the diagonal A to C
+ *  3. For XY_DIAG_BD measure the diagonal B to D
+ *  4. For XY_SIDE_AD measure the edge A to D
+ *
+ * Marlin automatically computes skew factors from these measurements.
+ * Skew factors may also be computed and set manually:
+ *
+ *  - Compute AB     : SQRT(2*AC*AC+2*BD*BD-4*AD*AD)/2
+ *  - XY_SKEW_FACTOR : TAN(PI/2-ACOS((AC*AC-AB*AB-AD*AD)/(2*AB*AD)))
+ *
+ * If desired, follow the same procedure for XZ and YZ.
+ * Use these diagrams for reference:

+ * Bed Skew Compensation
+ *
+ * This feature corrects for misalignment in the XYZ axes.
+ *
+ * Take the following steps to get the bed skew in the XY plane:
+ *  1. Print a test square (e.g., https://www.thingiverse.com/thing:2563185)
+ *  2. For XY_DIAG_AC measure the diagonal A to C
+ *  3. For XY_DIAG_BD measure the diagonal B to D
+ *  4. For XY_SIDE_AD measure the edge A to D
+ *
+ * Marlin automatically computes skew factors from these measurements.
+ * Skew factors may also be computed and set manually:
+ *
+ *  - Compute AB     : SQRT(2*AC*AC+2*BD*BD-4*AD*AD)/2
+ *  - XY_SKEW_FACTOR : TAN(PI/2-ACOS((AC*AC-AB*AB-AD*AD)/(2*AB*AD)))

+ * Bed Skew Compensation
+ *
+ * This feature corrects for misalignment in the XYZ axes.
+ *
+ * Take the following steps to get the bed skew in the XY plane:
+ *  1. Print a test square (e.g., https://www.thingiverse.com/thing:2563185)
+ *  2. For XY_DIAG_AC measure the diagonal A to C
+ *  3. For XY_DIAG_BD measure the diagonal B to D
+ *  4. For XY_SIDE_AD measure the edge A to D
+ *
+ * Marlin automatically computes skew factors from these measurements.
+ * Skew factors may also be computed and set manually:
+ *
+ *  - Compute AB     : SQRT(2*AC*AC+2*BD*BD-4*AD*AD)/2
+ *  - XY_SKEW_FACTOR : TAN(PI/2-ACOS((AC*AC-AB*AB-AD*AD)/(2*AB*AD)))
+ *
+ * If desired, follow the same procedure for XZ and YZ.
+ * Use these diagrams for reference:
+ *
+ *    Y                     Z                     Z
