When y axis endstop triggered, it dont finish the motor movement

Hi everybody,

While printer is homing, it is homing x and z. However, when y axis endstop is triggerd, it dont stop. Here my setting from configuration.h.

mismatch in homing direction / installed endstop switch

you have

#define MIN_HARDWARE_ENDSTOP_Y true

(endstop at y min)

but

#define Y_HOME_DIR 1

which means you home to y max.

so two problems :

if motor is homing in the correct direction its wrong in that case

so change the following two lines

from:

#define INVERT_Y_DIR 1 -->> #define INVERT_Y_DIR 0

#define Y_HOME_DIR 1 -->> #define Y_HOME_DIR -1

thank you so much, ı can home y axsi now but ı faced with another problem. in my first try, i homed z axis but then ı oredered to home z axis it moved down and triggered the z axis endstop then the motor got stuck and begun to make sound. curerntly when ı oreder z axis to move,motor dont turn and make sound. what are your opinions about this problem.

several possibilities:

motor not connected properly

motor current is adjusted incorrect

steps/mm don´t match

speed and acceleration to high

check motor connections and motor current , then

i´d suggest to reduce z-axis homing speed first , try 5 at the beginning then increase

When y axis endstop triggered, it dont finish the motor movement
