The purpose of this test and file is to determine settings for different materials for marking and cutting with a CO2 laser system.
Every material is different...
This is a test file you can download to use to test materials to determine the ideal setting when using your laser system. We've included a materials log for you as well so you can track your materials and keep a record. All materials are different, there's no EXACT settings to do anything using a laser, as laser output varies with age, and even materials act differently in different atmospheric conditions. You'll find a chart of recommended starting settings for various types of wood below.

Scroll through and follow the steps in the gallery below then proceed to the steps underneath as instructed on the last slide.
Analyze. Does your raster not look dark enough? Increase power, or decrease speed if you want it to look darker, or the opposite to achieve the same. Does your Vector Cut and Mark? Slower speeds and higher powers cut thicker materials. The cleaner line markings will happen at faster speeds (70-85%), deeper marks/cuts will happen at higher power, and/pr slower speeds. The longer the laser is in an area (the slower the speed) the more the material will burn, melt, or mold.
Record and repeat. Repeat the steps as needed to dial in your material after making adjustments to the recommended settings. Keep a log of your jobs, so you can mimic your success, and avoid your mistakes. Soon, you'll be a laser cutting EXPERT. There are millions of materials, so use the guide to decide what settings would be a good starting point to dail yours in even if you don't see it below.
Laser cutting and marking is a skill you must develop. Just because you own a guitar, doesn't mean you're going to be Jimi Hendrix ;-)
Settings are based on a 45w laser tube, adjust accordingly for other size tubes.

NOTE: Vector marking: start at 2-5% power and progress from there at 85% speed for bet results.
