Help Frimware Rostock Mini

I am doing Delta rostck project But I am currently loading frimware and when I give 3 axis X Y Z to origin. Only Enstop X and Y are enabled and Axis Enstop Z is not activated. Xi only helps me bypass
Currently I am using 3 Enstop for 3 X Z axis
But now when Auto Home is only X Y is activated and Enstop of Z axis is sticky and emit
When I ordered the Start Printer on the Repeater Host only the X and Y axes went down and the Z went up
