 * "Mixing Extruder"

 * 举例：2进1出混色机型，3进1出混色机型，5进1出混色机型，6进1出混色机型
 * 需去掉 #define MIXING_EXTRUDER 前面的 //
 * 通过M163 设定混合比例，M164 保存到指定虚拟挤出机。
 * 
 * 用2进1出混色举例：
 * 在切片软件的开始代码区添加：
 * M163 S0 P6  
 * M163 S1 P4
 * M164 S0 
 * 
 * // M163 S0 P6   指虚拟挤出机S0  挤出率为60%

 * // M164 S1  以上两个虚拟挤出机 S0+S1=100% ，定义为挤出机2 并保存

 * 在Simplify3d的切片软件中，最多支持6个挤出机，即 M164 S0（S1、S2、S3、S4、S5）
 * 也就是说，最多支持6种混色配比。
 * M166 是marlin2.0新增的梯度渐变混色指令，通常与 M163、M164 配合使用。
 * 举例：已知一个模型的高度为100mm, 开始渐变高度0mm, 结束渐变高度100mm.
 * M166 A0 Z100 I0 J1 S1
 * A0  指在0mm高度开启渐变混色
 * Z100 指在100mm高度结束渐变混色
 * I0 指调用M164 S0 的混色配比
 * J1 指调用M164 S1 的混色配比
 * S1 指开启梯度渐变功能 / S0禁用梯度渐变功能
 * 
 * M165 为专色混色配比指令（不与M163 M164一起使用），最多支持6个虚拟挤出机
 * 举例：
 * 6个颜色混合  M165 A1 B1 C1 D1 H1 I1 （各挤出机挤出率：1/6）
 * 5个颜色混合  M165 A1 B1 C1 D1 H1 （各挤出机挤出率：1/5）
 * 3个颜色混合  M165 A1 B1 C1  （各挤出机挤出率：1/3）

 * 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
 *    ^     B-------C       ^     B-------C       ^     B-------C
