### Describe your issue:

My Z axis only moves up and wont go down, I have tried inverting the dir\_pin and it doesn’t do anything. I am using a virtual endstop (biqu MicroProbe) and I tried moving the bed with with the probe deployed (z trigger open) which made no difference. Im at a loss here if anyone has any ideas let me know. Ignore the safe home z hop as i tried to check if it will even do anything (fails to home z but allows me to move it manually)

With z hop set to +5 it tried to home but it did not stop when touching the probe (probe deployed and moved to the centre of the bed as it should), forcing me to emergency stop it.

Any help will be appreciated as its my first setup with klipper.

Issue with movement direction sorted as I had a typo on the DIR\_PIN. Only other thing left is bed not stopping on contact with probe

I believe your z\_offset should be a positive value

```auto
[probe]
x_offset = -46
y_offset = -4
pin = ^!PD13
deactivate_on_each_sample = False
speed = 5
z_offset = -1.5
samples = 2
samples_tolerance = 0.05
samples_tolerance_retries = 3
activate_gcode = 
	Probe_Deploy
	G4 P1000
deactivate_gcode = 
	Probe_Stow

```
