FINALLY we can cut some FOCAL STICKS on the CO2 Laser!

[@eigregor83]

I still need to cut out focal sticks. All I ended up doing was marking the z height for each lens on the riser and then the materials that I engrave regularly I save the height setting in the material library. Any new material, I would measure and then add that material height measurement to my riser height. It has worked so far, but I still need to make some focal sticks.
