多Z参考配置

双Z单限位

• 在第二个Z配置无需添加endstop_pin:

  [stepper_z]
  step_pin: PA5
  dir_pin: PA4
  enable_pin: !PA6
  rotation_distance: 4
  full_steps_per_rotation: 200
  microsteps: 16
  endstop_pin: ^!PA9
  position_endstop: 0
  position_max: 300
  homing_speed: 50
  homing_retract_dist: 5
  
  [stepper_z1]
  step_pin: PB10
  dir_pin:  PB2
  enable_pin: !PB11
  rotation_distance: 4
  full_steps_per_rotation: 200
  microsteps: 16
  step_pulse_duration: 0.000004

双Z双限位

• 在第二个Z配置需要添加endstop_pin:

  [stepper_z]
  step_pin: PA5
  dir_pin: PA4
  enable_pin: !PA6
  rotation_distance: 4
  full_steps_per_rotation: 200
  microsteps: 16
  endstop_pin: ^!PA9
  position_endstop: 0
  position_max: 300
  homing_speed: 50
  homing_retract_dist: 5
  step_pulse_duration: 0.000004
  
  [stepper_z1]
  step_pin: PB10
  dir_pin:  PB2
  enable_pin: !PB11
  rotation_distance: 4
  full_steps_per_rotation: 200
  microsteps: 16
  step_pulse_duration: 0.000004
  endstop_pin: ^!PA10

双Z使用Probe或者BL Touch

• 在第1个Z配置endstop_pin:后面pin修改为probe:z_virtual_endstop

• 需要设置Probe或者BL Touch

  [stepper_z]
  step_pin: PA5
  dir_pin: PA4
  enable_pin: !PA6
  rotation_distance: 4
  full_steps_per_rotation: 200
  microsteps: 16
  endstop_pin: probe:z_virtual_endstop  
  # position_endstop: 0
  position_max: 300
  homing_speed: 50
  homing_retract_dist: 5
  step_pulse_duration: 0.000004
  
  [probe]
  pin: ^PB4                    # 信号接口
  x_offset: 0                  # X轴-传感器相对喷嘴偏移量
  y_offset: 0                  # Y轴-传感器相对喷嘴偏移量
  #z_offset: 0                 # Z轴-传感器相对喷嘴偏移量
  speed: 3.0                   # 调平速度
  lift_speed: 5                # 抬起探头速度
  samples: 3                   # 采样次数
  samples_result: median       # 取值方式（默认median-中位数）
  sample_retract_dist: 3.0     # 调平回缩距离
  samples_tolerance: 0.075     # 采样公差（注意过小的值可能造成采样次数增加）
  samples_tolerance_retries: 3 # 超公差重试次数
