Disable Arc-fitting will help. I don't think you need that anyway. If you do need it, do it in post with ArcWelder.

Try this: A4p.3mf.txt

If you print it laying flat on the bed, the thin fins will definitely break off. Hence the angled position, just in case you wonder.

Thanks for your suggestion, actually i've already printed many of these and they infact aren't straight due to the slicing. thins are plenty strong so not the issue there.

The issue I'm seeing is that Orca is adding material where it shouldn't

You need to change Wall generator to Arachne and Minimum wall width to 50% in order to make it work.

Strange. Have you changed the setting I saved in the attached 3mf?

[SolberLight]

I've tried your settings. It's clearly better, but not perfect, what should I changed next ?

What is the diameter of your nozzle? 0.4 mm or 0.6 mm ...?

[SolberLight]

.4 yes

Is it possible to attach the whole project file?

Plate.3mf.txt

Try reducing layer height to at least 0.13 mm. Preferably 0.1 mm.

[SolberLight]

That's a good point that should help. Still there should be a warning or something in orca in this case. print shouldn't start without advice
