Very similiar topic here:

Laying out a grid to establish zero/home on waste board

hey all, I just finished my build and im getting ready to start messing with this thing. I notice on older models of x-carve that they have a grid that aligns with easels plotting. whats the best way to make sure my material is where its supposed to be in this dimension so as to work with easel in the 2d world? carve a grid into the board? any best practices would be greatly appreciated. thanks for your time.
