Chrome tanned leather and engraving

Another factor to consider when cutting some materials that are less desirable (like chrome tan leather, PVC, polycarbonate etc) is the gas given off can coat the lens. This coating will etch the surface thereby reducing the effectiveness of the machine. This coating  and the damage will require the replacement of the lens.

Yeap i know it :) but i dont cut it, Just engrave some letters and numbers

This has not been my experience when cutting leather.

My laser cutter has an air assist pump that forces fresh air through the nozzle when in operation, and a ventilation system that removes the smoke from the cutting area. The lens is located 2+ inches away, up inside of the laser head, much removed from the surface of the material being cut. None of the smoke I make from cutting leather reaches the lens, and I have never encountered the issue of etched lenses. I'm only speaking about leather (chrome-tanned and otherwise), as I can't speak to PVC or poly-carbonates related issues.
