Z limit switch not homing just keeps running heeelp Please

Just finished and built my machine 1000 x 1000 and all seems to be working fine apart from when I start the homing , when the router rises to touch the limit switch it des not stop , I have tested the switch and it’s working fine and also tested in machine inspector and it’s shows green when switched ? , thanks in advance

Use machine inspector -> advanced to get the grbl parameters ($$ output ) and post them here.

Check the limit switch to make sure that the moving carriage will trip the switch before the carriage hits the hard stop.
