X axis move on the right only

Vertex 3D Printer Vertex - Issues while printing
1

Hello

I have a problem with my K8400. After 6 months of good printing the X axis move only on the right side an don’t want to move on the left by using the “moving axis” command. The Auto Home become impossible. I change the mother card, the driver, the motor and nothing no change. I notice that one of the little red LED on the mother card close to the X driver is lighting during left X move. And when I try a right move the closer red LED have just a very little light and often no light. I check all the connection I try to exchange the connection but nothing works Could you help me to solve this problem.

Sorry for my bad english

Thank you by advance

Christian

This sounds like an end stop problem.
Try cleaning it with a Qtip.
