Change this line to :
#define DEFAULT_MAX_FEEDRATE {500, 500, 3, 25}
This will make the stepper work again. With "5" it was to fast ( and noisy )

Have you checked the two z-sides, if they run parallel?
I found my M5 nuts on the z-leadscrews were not aligned and all the weight rested on one z-rod. That can cause noise too.

I don't believe Olaf is correct. As you can see in the picture, when the Y-endstop is triggered, the extruder Y position will be at 0, which is min.

In the picture, the green arrow represents the 0,0,0 position. When an endstop is at the opposite side, it is a MAX. endstop. It is even written y-max. on it.

The green arrow represents x=0, y=0. y=0 is achieved by moving the bed towards the back, so that's a MIN endstop. Max Y is achieved by moving the bed forward. The diagram is incorrectly labelled for normal usage. Whoever created tripped over the reversal due to the relative motion of moving the bed instead of the head.

Stack
My X end stop is a max (Like the pic) My Z is a min (like the pic) but my Y is a min (different from the pic). My home position is diagonal from the one in the picture.
