Well the engraving tolerance is actually placement tolerance and it&#x27;s a little bit exaggerated. We have seen so complex parts that it&#x27;s impossible to have it engraved perfectly. Normally, we overlay the actual product outline including the engraving design and it&#x27;s aligned perfectly. For your application (control panels) sounds to be extremely easy to be perfect. You can drop us a line at hello@lasergist.com and discuss in detail.
