log (1. I make the home but at the end of the race it makes the second home only on the z axis and not also z1. The y axis moves a bit and stops, as if it hits the trigger midair - even when it is around the center of the printer - followed by the retract motion. Assuming that the toolhead moved a millimeter or so and then stopped, change the VALUE to decrease the sensitivity by 5-10, try again, and keep going until you find the first value that Klipper supports a mechanism for homing with an endstop attached to one micro-controller while its stepper motors are on a different micro-controller. The module registers an extruder homing command, creates a virtual toolhead with only the extruder stepper, and passes it to the homing move. Comment out position_endstop.
