Dual Y axis machine endstop problem (no replies)

Hello. I am having a homing problem with a custom machine. It has 2 motors on the Y axis, and separate endstops for each motor, connected to the Y_MIN and Y_MAX slots.

If I have Y_HOME_DIR = -1 everything fine. Both motors home separately to the Y min position and stop individually when I press each endstop with my fingers. The problem is that the endstops are at the end of the Y-axis. So I changed Y_HOME_DIR from -1 to 1. Now the motors move in the expected direction, but they don't stop when hitting the endstops. Am I missing some parameter here that also needs to change? Like changing the Y_MIN_POS or Y_MAX_POS?

Thank you in advance for any help.
