but I never got to the bottom of it :(

Are you involved in programming KISSlicer? I mean do you together (with jonathan) write on KISSlicer code?

No, this is Jonathan's project. I just do my best to assist, and I am a programmer, but this stuff is way too complex for me. The best I managed was a post-processor for SNMM printers :(

Anyway, I have news.

The problem in this instance is not the Oversampling Resolution. All that does is change the surface point position.

The undercut on the gear where the bridging occurs is precisely 1.5mm. At 0.2mm layer heights, KISS is sampling at 0.1, 0.3, 0.5...1.3,1.5,1.7... mm heights. In other words exactly at the height of the undercut/bridge of the gear.

Unfortunately, the triangles making up the skin of the model may not be exactly precise and this causes exceedingly small "dimples" in the surface, and those dimples show up on occasional sampled points (depending on which surface points are taken into account - hence resolution changes the points) and end up having their own perimeters.

There are a couple of solutions.

Amend the model such that the undercut on the gear is 1.49 (or 1.51) mm. Or slice with layer height of 0.2005mm or even use adaptive layer heights. Anything other than have the surface precisely in the middle of a layer.

So, the good news is that this is not a KISS fault; KISS is slicing the model correctly, but the model has some extremely minor faults :D

P.S. I just wish I new enough to diagnose this stuff myself :(

Here , up to now, all goes well with the new alpha release. The underextrusion after layer change is away . I also did not see the problem of settings getting destroyed .

No, but there will be one when the beta is out (currently on alpha releases).
