Very great visual and proof of concept! This is what I was thinking to do, since I know the grid infill option Cura has works well, and although it doesnt stop extruding over the intersections, it should be more than sufficient. I am however, not an expert at the program, so I may need some guidance as how to remove only the necessary holes, then add support structure in place whilst maintaining the precision of the part. I can easily modify the part in Inventor, but again, I need to maintain the position of the grids.

I wouldn't really have a problem with this pathing, since the efficiency loss isn't a big deal, but the problem comes when printing it. The resulting prints resemble more of a blob than a grid.

This is another view of the file, its an Autodesk Inventor part converted to STL. The grids unfortunately need to be in specific locations, otherwise I may try modifying the print in some other way. I purposefully made the grid size the width of a single line, with the hole being 1mm wide, but for some reason it just doesn't behave as expected. Here is another image as well. It looks like it is more random than just going to the 'nearest island' since it also seems to be inconsistent what it chooses as an island, indicated by all the white sections at the grid intersections presumably because the program didn't complete those paths.

I have an issue when making fine grids, this program seems to very randomly drag across instead of doing a logical maneuver. Is there a way to fix this?
