I made my printer using BTT Octopus Pro and i have 4 Z motors with individual endstops,
The problem is when I’m homing Z, after triggering first endstop all z motors stop but klipper sticks in Homing and after a while shows “No trigger on z after full movement”

• You need to define the respective endstop_pin and other homing relevant parameters for each [stepper_zX]
• If you should be using TMC drivers, then the relevant settings are missing altogether

As you see I defined endstop_pin for each motor.

I’m using external drivers and all motor moves correctly.

Main problem is stopping all z motor movement in direction to endstops by triggering first endstop and failed to homing. when i triggered other z endstops manually all motors start hoping and back to endstops and The problem occur again.
