Hi

Welcome to the world of engraving.

You have two options with pet tag engraving. The simplest is diamond drag, this is when you use a sprung diamond to scratch the surface with the spindle rpm off. This is great for neat, quick result, and although it is not deep enough to colour-fill, you can use a wide multi-line font for easy reading.

The alternative is, as per your target sample, deep engraving, colour-filled. Your 0.2mm cutter is good for single line letters 2 - 4mm in height. Set the spindle lock to 3 which fixes it, and in your tool set up, set your pass depth to 0.1mm and feed/plunge rates to 10mm/s. See below:

Not all materials engrave as well as you'd expect, leaving a burred edge. You often need to lubricate the surface of pet tags with some form of coolant, such as a light oil, or something which will evaporate to save cleaning.

Give it a go and let me know how you get on.

1000% BETTER but it will not work using a single line font?!

The shown screen shot is what I get when ONLY using single line fonts....standard fonts work but give an outline cut
