### Describe your issue:

I am working on running my printer and having trouble with the Z-axis. Whenever I go home all axis, it says the Z end-stop is constantly triggered. I don’t have a z end-stop. When I take the z end-stop out of the config file it says I have to have a z end-stop. Thank you in advance!

As for the klippy.log, you like to have:

```auto
[stepper_z]
step_pin = PB8
dir_pin = !PB7
enable_pin = !PE0
microsteps = 16
rotation_distance = 2
full_steps_per_rotation = 200
endstop_pin = PF2 # <----------------
position_max = 400
position_endstop = 0
position_min = -50
homing_speed = 8.0
second_homing_speed = 3

```

If you want to home with a probe - would be nice if you would have mentioned in your post - things work differently.

Thank you, I forgot to mention the fact I was using a probe. I have defined the probe and tried putting the end-top pin as the probe, however I just get the following error.  
Option ‘position\_endstop’ is not valid in section ‘stepper\_z’

Please aways post a klippy.log, not a printer.cfg. The log gives us more information.

```auto
[stepper_z] # Left
step_pin: PB8
dir_pin: !PB7
enable_pin: !PE0
microsteps: 16
rotation_distance: 2
full_steps_per_rotation: 200 #set to 200 for 1.8 degree stepper
endstop_pin:probe:z_virtual_endstop
position_max: 400
position_endstop: 0
position_min: -2
homing_speed: 8.0
second_homing_speed: 3

```

Try with a space behind `endstop_pin:`

```auto
endstop_pin: probe:z_virtual_endstop

```

Still getting the same error.  
“Option ‘position\_endstop’ is not valid in section ‘stepper\_z’”

Oh it was `position_endstop`. Sorry.

With a probe, you do not have this parameter.

Perfect! I ended up removing the position end-stop and it works like a charm. Thank you for the tips on sending in these support tickets and my printer.
