After the Cura Update to 2.4 I figured I would give Cura another chance......and nope, infill is still junk. No idea how they can even call their "stock" settings remotely good. The outside of the part may be ok to look at, but the inside is just a messy glob of infill failure. You have to slow it down to 25% and have a 2 day build. (and it still looks, and functions, poorly). There are plenty of example why a good infill in needed.
Its like Cura programmers are wanting people to buy Simplify3D. LOL
