Adjust x/y value after clicking home

after clicking on home the value of x/y is negative and never presents the ideal value x0 y0 or already adjusted after the endstop button is removed, does anyone know how to adjust this parameter?

You need to start your machine with the laser head at the front left of your machine. By doing so, the position of your laser at that time will be 0,0.

If you have added limit switches to your laser you may need to make some configuration changes to get this to work correctly.
