Hi Terry,
I came across this post. Nice to quoted. 600 dpi means twice as many dots as 300dpi so you would halve the distance between dots (scans). So the scan gab would be .084/2 = .042
By the way, I very seldom or ever use 600dpi. First it's really slow and on most materials doesn't show. What I sometimes do is use a 250 or 300DPI screen in photoshop and engrave at 500 0r 600dpi. Trial and error I suppose; no absolute rules.
The other thing to keep in mind is, machines have 'native' resolutions. This has something to do with the increments of the drive motors and the size of each small step. There is 250/500 and 300/600. My Rabbit HX6090se engraves much better with 250/500. I'm not sure about other Chinese lasers but I expect they may be similar. Open to correction here.
Hope it helps
