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

    [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

    [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
