测量杆长：
DELTA_DIAGONAC_ROD= 214.0
测量三个轴滑车均到达最高点时挤出头离打印床的距离，稍微减少一些作为调平余量：
DELTA_HEIGHT= 250.0
发 G1 X0 Yn 试验n可以达到的最大值，测试可打印半径：
DELTA_PRINTABLE_RADIUS= 85.0
计算各轴电机走1mm需要的脉冲数：XYZ轴使用 Prusa Printers Calculator 计算(1.8°步进，GT2同步轮齿距2mm，16齿，RAMPS为1/16 microstepping)；E轴根据挤出轮直径12mm，算出周长37.7mm，步进电机转一周3200个脉冲（与XYZ轴计算类似），得到每mm脉冲数84.88
DEFAULT_AXIS_STEPS_PER_UNIT= { 100, 100, 100, 84.88 }
Slicers prepare a solid 3D model by dividing it up into thin slices (layers). In the process it generates the G-code base on printer parameters.
3D printing host software. Communicate with the printer to control and send G-codes.

List of G-codes can be found in RepRap and Marlin (only implements a subset).
