weird homing behavior

secure

Video is better to explain the problem;

I don't know why/how X triggers before it hits the switch but I think I may be trying to home the printer where it shouldn't be? X/Y switches works without any problem. Center origin X0 Y0 is the physical origin center point of the bed. The bed size 500mm x 500 mm but the axis movement limits X400 Y430 Z500 mm

Here is my config.g code

What kind of endstops are they?

Increase the distance of your homing moves to be larger than the full size of your bed. Are you have it now, it would only be able to home successfully if you start from the center of your bed.

Are you sure your axis limits are correctly sized?

Is this a corexy?

Basic micro switches
Exactly. It is successfully homing if the head starts from the center of the bed. If not, XY sw may trigger randomly. I tried to increase distance but not remember if it was larger than the bed size. I will try it again. Thanks
Yes with some margin.
