I'm having trouble with homing endstops. I'm using optical endstops. I can move the carriage around no problem. It moves in the correct direction.
When I move the carriage over and trigger X and Y it shows:
X_min:1 Y_min:1 Z_min:1 pins- (XL)P1.24:1 (YL)P1.26:1 (ZL)P1.28:1
It appears that homing Y is working. When I try to home X it moves to the right instead of moving to the left where the end stop is.
Here is the entire configuration:
