I am going to mount the Atomstack to a bench as I will be adding a Yaxis rails, Once I am affixed to the bench I would like the laser to start at the Yaxis 0 on the machine ruler and the same with the Xaxis set to the 0. I want to place two register boards one horizontal and one vertical, this makes sure my cut is square with my world.
Mount the laser frame so it does not move. Use the laser to burn lines across the X and Y axis. That will be your guidelines for mounting the register boards.
