Describe your issue:

cant home z-axis.
When homing “all” from Mainsail x,y works fine, Z lifts a small amount goes to enstop, back to middle of build plate, drops bltouch sensor needle and stops
when looking in console it states : BLTouch failed to verify sensor state
I have tested according to config doc and it works (BLTOUCH_DEBUG COMMAND=touch_mode etc.)
I am totally new to klipper and trying to go from Marlin to Klipper.
don’t know how to troubleshout this so any suggestion are highly appreciated
