I’ve also been using Inventables 1/8" Padauk. I mask it with paper tape. For unmasked wood I’d subtract about 5 from the power settings to get similar results, but I strongly suggest masking it.
For my Dala horses I used the following settings:
All cuts were at 210/Full (Pro) power.
I think I’ll try a slightly lower power or higher speed next time, as this cut through very easily but left quite a bit of char. I was able to remove most of it with alcohol but not quite all of it. I’l be trying Windex wipes on another batch.
Upper-left
Score: 125/11
This was in focus, so it has 0.18mm wide lines.
Nothing particularly special to report. The lines are very crisp and clean, almost as if they were drawn using a pen.
Lower-left
Score: 200/40
I adjusted the focus to be 0.3" above the surface of the wood, to get thicker lines. The lines end up with a V-shaped cross section. At the surface they’e about 0.45mm wide. The narrowest part of the groove at the bottom is fairly light in color but the sloped sides are charred.
I like the way this one turned out, although the start/stop points are more noticeable than a normal (in-focus) score.
Upper-right
Engrave: 1000/Full (Pro) power @270lpi
This went about 1.2mm deep into the wood and charred it quite a bit.
Lower-right
Engrave: 1000/60 @225lpi
This only went about 0.2mm deep and only slightly darkened the wood, making dark red marks. I like the color, but I think I’ll try slightly more power next time to make it a bit darker. The lower LPI setting seemed to be sufficient on this wood due to the fairly coarse grain it has. I might even try it one setting lower next time.
