Progress on Path Smoothing / Lookahead?
-
@CCS86 Well, all I can say is that the latest PrusaSlicer has arc fitting and it seems to slice as fast with it active as it does without on my Mac M1.

Have you looked at the code?
It's easy to go fast when you don't actually fit arcs.
Plus, even when successfully fitting arcs, they inject some variability into the wall surface. You can see something similar if you make the slicing resolution more coarse.

Yes, I did look at the code.

@CCS86 We do not need to argue about this. Fitting arcs will take longer than not fitting arcs, but there are some (many, probably) use-cases and examples where the time difference is trivial. Your experience is vast and your opinion is valid, but it is quite likely that I also have relevant experience.

It's called a discussion, not an argument. That's the whole purpose of this forum.
If you have relevant experience that leads you to a different conclusion, let's hear it. Just saying that you "likely... Have relevant experience" isn't very compelling.

I put my g-code resolution back to the default value and it started generating arcs. It only does it on external perimeters though. So artifacts from linear segmented inner walls can still print through.
But again, for the sake of our discussion, until RRF allows true arc support, the quality with G2/G3 is worse than without.

@dc42 is this just not going to be explored?

@CCS86 I think the main focus right now is getting 3.5 out the door.
