LASER ACCURACY TEST

Use this test-file to check your machine mechanical accuracy and laser spot thickness.

The best results are obtained by running this test file on a piece of anodized aluminum, laser perfectly focused, using maximum power and F500-F800 speed (for a 5.5W optical power model, 20W electrical power). Speed and power should be adjusted for different laser power and material.
