Inefficient routing since ver. 2.7.4
Hello,
when printing some kind of mesh, for example a hexagon one, the order in which the hexagons are printed seems to be quite random, when using the recent Prusaslicer releases.
This results in a lot of unnecessary print head movements, thus longer print time.
Version 2.7.4 is the last one known to me, which still did routing in more sensible order. Please see the enclosed pictures, made with versions 2.7.4. and 2.9.0.
Why has this changed so, and is there some setting that I could use to make 2.9.0 behave more like 2.7.4, in this respect?
Thanks and regards,
Kari

I don't believe there is any setting you can change to make it more like 2.7.4. You could try and play around with the seam settings or change the slicing back to classic instead of arachne but I don't think you will have much luck.
There are MANY issues open on the PS github regarding path planning so its not like this is an unknown issue. Just go there and select the Path planning tag, https://github.com/prusa3d/PrusaSlicer/labels/path%20planning?page=2&q=is%3Aopen+label%3A%22path+planning%22
People have been complaining about it since way before 2.7 though, almost as long as the software has been available.
In fact one of the longest issues about it specifically complains that it still sucks in 2.7.4 https://github.com/prusa3d/PrusaSlicer/issues/11658

OK, thanks for your answer. I just happened to notice this after upgrading from 2.7.4, because I then had a project involving a hexagon mesh, similar to the test print I used in the images above.
If I slice the same piece with Cura or Slic3r, then the routing is much more sensible.
Perhaps I'll move to use Slic3r then, although otherwise I like Prusaslicer interface and usability more... :/
