Vertex 3D printer. Auto Home doesn't move x-axis to startpoi

I have a new attached printer Vertex 3D printer (K8400). At first start Auto Home feature was good. After a few starts only Y- and Z-axis moves to the starting point after Auto Home enabled. X-axis makes a small movement just as it were already at the starting point. I have checked all the connections and the diode in the End-stop connector lights up.
What is the error?

Can you move the print head by hand?
If not look at this link.

Try swapping the end stop to a different location to see if the problem moves with it.

Thanks!
Problem solved!
A drop of oil on the y-axis end-stop-connector caused the problem. After cleaning the connector Auto Home works as it should!

Oops,

I meant to put that out there as well.
Glad to hear it’s working.
Enjoy!
