Well, I was wrong. Apparently it’s exactly the same at every speed. I don’t know how the image with pine in it had the lines so close together. This is essentially what I’m battling, a seemingly completely inconsistent result. Some days I swear I come out to the garage and it works for a few burns, and then the next day, or ten minutes later, it’s not working.
In this image, each row has 1 speed and power. I have it this way because as you can see the pattern appears differently across each 40mm x 20mm square. Each square was engraved individually.

Edit:Fixed grammar and tried to clarify engraving.
