These thread may help, but it's very simple. Connect 2 N.O. home switches in parallel to D9, and the default is lower left corner.

Thx wil it act as limit switches as well ? And since I want to use it as limit switches I need four switches? One at the front and one at the back for Y movement en on the top rail that houses the laser one on the left and one on the right for X movement? And do I just connect all of the in the same plug to jumper 9 ?

You don't need limit switches if you have home switches as you can tell Grbl the machine sizes and after homing it will ensure you don't run off the limits.

Of course you can add limits also if you choose but will need to configure and compile Grbl to make your custom firmware.

You should choose another pin for the upper limits but can use the same switches for the home / lower limits if you like.
