1 month ago Additional thing I've noticed today when slicing up another file. It appears that Octagram Spiral top infill layer is also creating individual central points now. It also appears to be doing similar with the bottom infill layer as well.
Again, this is pretty cool the way whatever it is that broke, broke, but this is really weird and not the way it used to slice.
Description of the bug
The Archimedean Coordinates for the top infill is not working as expected. Usually it goes off of the center of the model and spirals out from there. For some reason, the latest update that was just pushed out to me (2.8.0) is doing something really strange and seems to be doing several spirals in the middle of different sections of the model.
I was unable to find anything in the patch notes to indicate something was changed, but it just started doing this after the update. Checked a few other models of mine as well as downloading some older versions and found that whatever was changed seemed to affect ALL versions of the slicer regardless of version on my computer.
Was on an online chat with prusa support and they suggested submitting a bug report and, for the moment, trying a fork which did wind up fixing my problems. This is the July 2nd release of SuperSlicer.
I am uncertain as to what may have changed, but, if possible, can this become a togglable feature and not a bug? Being able to at least semi-control the center point of some of the infills like this would be AWESOME.
Mostly because the file displayed is a private commission I am working on, the project reproduction file will be a stl dummy file that shows the same properties.
