I did get his engraving nozzle from Cloudray and I used it on the images in the posts above. That last one without banding was done at 254 dpi. The first one with the multiple bands I calculated I should have been able to do 846 dpi with a .03 dot but I ran it at 480 dpi if I recall correctly. I think both turned out very nice but i haven’t taken the time to really try to analyze them yet. I was more concerned with getting the banding resolved and getting the camera set up last night.
See this post for a photo of the dots…
I also ordered some card stock similar to what he uses and that’s also used in the images above.
