Azteeg x5 mini -deltabot- homing/enstop error

When I send g28 to my printer all three axis move up, but once one of the carriages hits the endstop, they all stop. so if the x axis carriage is higher than the others, it will move all three axis up, but all three stop when the x axis carriage hits the endstop, while the y and z have not hit the endstops.

Any suggestions? I can take a video if you need it.

Hi !

What does M119 answer when the endstops are hit, and when they are not ?

Are you sure each endstop is on the right tower ?

Cheers.
