Sounds like a polarity problem on the opposite end of travel. If it looks to the controller like the far end travel limit switch has been "made", it won't allow travel in that direction. This presumes of course that you have travel limits on both ends of the axis.
If you have the limit configured for NC (normally closed) and there's a wire break, it looks to the controller like the switch has been made, because the line will be open. Check continuity.
I am not sure how to check this. is this a firmware issue?
I have my X axis inverted with the endstop on the left side by the X motor
Have you already uncommented the DISABLE_MAX_ENDSTOPS in your configuration.h? If not, it could be that the X max endstop input is floating upwards enough to be detected as X being at the max endstop. It seems to me that the effect of that would be homing until the min endstop switch closes, but the carriage won't move away from that (possibly for either the homing tap or a manual move) since Marlin thinks it's already at max X.
If that happens to be it, credit clough42. He pointed out the DISABLE_MAX_ENDSTOPS issue with Marlin defaults a few weeks ago.
"uncommented the DISABLE_MAX_ENDSTOPS in your configuration.h?"
that fixed it!
you guys are a lifesaver
next thing i need to fix is setting a servo delay on retraction.
i needs to wait until Z is at a certain height before it retracts or it bump the who Z axis up for a second
