BL Touch
Start up = probe getting up and down
I can run commands pin_down / pin_up its works perfectly and the led light is also ON OFF according.
when sending BLTOUCH_DEBUG COMMAND=touch_mode
showing Probe: Open
Then while gently pushing the pin up slightly with the nail ans send QUERY_PROBE
also showing Probe: Open. It’s not getting triggered.
I am using MKS Eagle motherboard, and Printer kinematics is cartesian

Genuine BLTouch or clone?
For clones this behavior has been reported before but they will work anyway during a real homing.
Follow BL-Touch - Klipper documentation (last two paragraphs under “Initial Tests”)
and BL-Touch - Klipper documentation for information about clones.

Thank you for your reply, Did the same thing as per the documents but the same problem I am facing.
Also when I am using the same BL Touch in marlin firmware for Z_Min homing its works perfectly… While in Klipper it’s not triggered.
