Need help with stopend switch.

Have followed this, do you know rotation on x y z stepper motor, maybe also my problem with switch.

NC normaly means not conneted you have to use NO & C
on a switch NC is normally normally closed, and its preferred for limit switches as it would prevent movement if the wire breaks.

can any of you help me with that.
maybe post a picture of switch and duet connection?

some pictures , where it appears that the endstop LED is on, but Z Y X is not in the home position, if I press each switch, the endstop LED is off on duet2wifi.
Should it be so?
home position OFF, not home location ON!

I suggest you start by testing the endstop switch and wiring. See https://duet3d.dozuki.com/Wiki/Connecting_endstop_switches#Section_Test_endstop_switches.

Have fixed now, by changing the switch to NO and working now.
Thanks for the help.But one more question, how can change the speed of Z axis on the way to endstop (low switch) to a slow speed last cm to endstop. The same speed, as on the x and y axis. I have this config.g

how can change the speed of Z axis on the way to endstop (low switch) to a slow speed last cm to endstop.
It's not possible to slow down before the endstop, because it doesn't know where the endstop is before being homed. Typically homing would be done in two passes. A fast movement to the endstop, followed by a short movement back, and then a slower movement towards the endstop again for better accuracy.
