non-planar support extrusions which the nozzle later crashes into #3304

What happened?

i noticed the z axis moving while laying down support. then i heard the nozzle running into the support. the slicer shows these extrusions.

what is going on here? i might have heard that sound before, but i explained this with overextruded layers sticking out...

Project file & How to reproduce

In future can you please just attach the project file from SuSi. File>Save as. That creates a 3mf file which already contains the model and ALL the settings in use as well as as modifiers, variable layer heights, placements etc.

We can then just open it and slice with the same settings you are using. There's always the danger that when we add things manually from the files people provide that something will effect trying to recreate an issue.

In this case though its very simple. You have sawtooth pattern selected for the support material interface (Print Settings>Support Material>Options for support material interface>Pattern).

I will look into the settings, thank you.

as much as I like the idea of 3d extrusion paths, what made me look at this as a bug is the fact that the nozzle crashes into those bumps constantly. I had similar problems before when experimenting with layer and support heights.
