I also decided to try my hand at engraving with the CNC. Theoretically it should work great but in practice it didn't start out so good as you will see in the pictures below. Just for future reference the settings I used for the CNC are 6 IPM at .01 depth for the engraving. The depth number was a bit arbitrary since its really hard to set it exactly. What I ended up doing was to run the depth at .01 and then run the job a second time after lowering the Z0 setting by an appropriate amount to get the letter width I wanted.
