im no professional but try unhooking the wires going to the motors and try moving the x axis to the homing spot and see if you see any obstruction between the switch and the plate that it hits .

There is a basic page on troubleshooting the homing switches at:

Please check that the switches are plugged in correctly, work properly — when the machine powers up the homing indicator lights should flicker on/off, then once the controller is booted up you can test the switches by pressing them — the matching light should light while the switch is pressed (closed), and should go off when the switch is released (open).

Please make sure that the machine can mechanically close the appropriate homing switch on an axis before reaching the limit of travel along that axis — if it can’t, it should be possible to adjust a problematic switch’s placement by loosening the hardware in question, pulling it into a better alignment and then tightening it.

The machine being out of square can also affect this, squaring up the machine, or more expediently, securing a small block or plate for the homing switches to contact may be necessary.
