Changing Top Surface Texture
I have a Neptune 4 Max, but this question could just as well pertain to my Ender 3, as I believe it's more of a slicer setting I don't know of, or may not even exist. I'm posting a JPEG of a speaker grill I designed in Freecad. When it prints, there seems to be no sense as to how the print head moves. It'll do a few triangles here, then skip to some other spot and print a few there. and by the time the top layer is finished, the surface texture of the finished part looks awful. I'm trying to avoid sanding and painting. Is there a slicer setting that makes the print head just print one entire straight line at a time, starting on one end, going all the way across, then doing the next line below it, and so on? Thank you.

I've had a similar experience where my print may have succeeded if only the slicer had made longer straight lines instead of jumping around. I searched this question and all I found was there was no way to control the printer path. The only thing I can think to do would be to print it at some kind of an angle. I wonder if you could just raise one edge like 3mm and let it print supports if that would be enough to force it more or less to print in longer more concentric lines? I assume you're planning to print it outside up so even if you struggle a bit to get the supports off cleanly it won't matter since that part will be hidden. If this works it should also have a pretty decent effect for the finish. I printed a mesh using circles which turned out pretty good, and it would print circles as each circle but would probably not jump around from one area to another as much or in as big of jumps...?

You could start the print at an angle and only print some of it vs fully committing and trying to print it all. I do small test prints a lot to cut down on wasted time later if something fails. Try breaking out a strip just to see how it goes..?
