So what’s the purpose of this post?
Are you telling us what you are doing or do you have a problem?
If you have a problem, then you should have filled in the information that was requested of you (and included your `klippy.log`).

Without looking at your board pinout, That looks correct.

You’re going to have problems with your BL Touch.
You can only have one Z axis endstop and you need to set up your BL Touch according to:

myke is right, I missed the BLTouch part. You’re better off setting your BLTouch as a virtual z\_endstop. See the link he posted along with these sections
[https://www.klipper3d.org/Config\_Reference.html#bltouch](https://www.klipper3d.org/Config_Reference.html#bltouch)
[https://www.klipper3d.org/Config\_Reference.html#probe](https://www.klipper3d.org/Config_Reference.html#probe)
Once you get that setup your config will look something like this… (this is from mine, though I don’t use a BLTouch)
```auto
[stepper_z]
step_pin: Z:PB4
dir_pin: Z:PB3
enable_pin: !Z:PA15
rotation_distance: 40
gear_ratio: 80:16
microsteps: 16
endstop_pin: probe:z_virtual_endstop
position_max: 310
position_min: -10
homing_speed: 20
second_homing_speed: 3
homing_retract_dist: 3
```
