Z axis dont stop while printing

hello everybody.
i build my 3d printer with endstops on min and max of each axis. all work fine when i move them by the printer screen or the pronterface on the laptop, the axis stop in time as the endstop bright.

when i start printing the hotend increase temperature and then the printer makes a checkup for the limits. goes to X in and then to max, goes to Y min and the to max, and with the z axis goes to Z max and everything is good, the problem is when it goes to Z min it doesnt stop even it it the endstop.
i Will be very thankfull if anyone can help me.
i use mega 2560, ramps 1.4 and marlin software

Try to testing your End-Stops using M119 to determine if your end-stop are functioning.

Still not working would be to Upload your Marlin configuration_adv.h an configuration_adv.h to a share system like google drive, then attach a link to a post.

This way we can look at you configuration files.

I tested and they work fine
pronterface says: zmin Triggered

what type of axis does your machine have? in particular the Z axis

does the bed go up/down, where is 0 top or bottom of travel?
does the bed move in Y ie like a I3?

or something else?
