I’ll throw this into this category for lack of a better guess, not sure if it’s hardware or software related.
I converted this logo to a vector and ran a test burn today. If you zoom in on the photo, you can see the “dots” in nearly every line. Seems to me they’re at the beginning or end of the travel.
I’m using Lightburn as my laser control software, and worked on the vector in Vectric Pro as I’m not proficient in Inkscape yet.
