Laser gauge for K40D and regular K40 without nozzle, to set proper height between material and lens.

How to use:
The guage has steps, use the highest one for engraving, set the gauge between material surface and lens holder underside.
For cutting, take 50.8 minus half material thickness, use that to set proper height.

Example: 4mm acrylic, use the 48.8 step (50.8 -2 = 48.8)
