We used a 50 watt Helix with the following settings for the wood gauge: engraving - 70% speed, 100% power, cutting - 10% speed, 100% power, 500 frequency.
If you'll be engraving the back of your gauge, simply flip the material over and send the job. Wipe off any excess wood residue and you're all set!
Use the same technique described above for other materials like plastic or acrylic. Here is a sample that we created from engraveable plastic using the following settings on a 50 watt Helix laser using engraving settings of 100% speed, 30% power, and cutting settings of 30% speed, 50% power, 5000 frequency.
