Engraving experiments in pine

settings

#1

I had some 10x12" 3/4" pine boards (standard martial arts breaking boards) lying around and decided to try engraving them with different engraving settings. I thought I’d share some preliminary results. I’m also going to go over some things I had to learn which most of you are already familiar with.

First, I had to track down instructions on how to engrave without the crumb tray because 0.75" is greater than the 0.44" maximum focus height. Measuring the black crumb tray bed height, I got 1.37", which is consistent with what other people have measured. I needed a spacer between 0.62" and 1.06", so I used a second 0.75" board. Because of warp, the two boards together measured between 1.5 and 1.6" high, so I calculated an average of 1.55" and used a focus height of 0.18" (1.55 - 1.37).

Secondly, how to decide on settings? I saw suggestions that recommend using max speed and adjusting power for engraving, so that’s what I did, trying various settings between 50 and 100. 50 was too light, 100 really eats into the wood; 80 gave a decent black without going overboard. Finally, what engraving method? I tried Floyd-Steinberg and map power. Map power may give a nice result in other materials, but in pine, the grain really stands out as light ridges in dark areas, and the light areas are more contoured than darkened. Floyd-Steinberg does a better job of visibly bringing out the details.

Thanks for posting this! I picked a pine board last weeken to play with. Gives me a great starting point.
