That's an interesting request - basically what you're saying is reduce internal features to the minimum print speed before touching the external features, right?

Seeking testers and feedback for this before I invest any more time in polishing this and making it a feature.

Yep, printing inner features slower feels weird but it makes sense when trying to make outer surface more consistent.
Can't wait to try this. MSVC doesn't report build progress which is annoying.

I don't think it's working for me. On some layers, travel speed is applied to the outer wall while on some it's 10mm/s.

This is the same model, in 2.0.

I've pushed an updated version - found the issue (I think)...

Fixed:

Weird. Looks like if dropping the inner lines' speed doesn't slow it down enough, it immediately sets the outer wall's speed to a very low value instead of gradually slowing it down. Or is this feature a special case and isn't implemented yet?

Drop me your project file as a zip file here to take a look.

also try slicing with slowdown for overhangs disabled - there is some interference there as I've not fully debugged the feature to fully work with all parameters. Looking for feedback on whether this addresses the core issue and then I can work in polishing the feature if it does. It works a bit better with classic overhang mode enabled if you need the slowdown.

Confirmed - it doesn’t play nicely with slowdown for overhangs as the feature is not fully implemented yet. However for a test and POC it should do the trick for now

Yeah, even with classic mode it's acting weird. Currently thinking about what to print that has no overhangs and is small enough that the artifacts due to inconsistent outer wall speed would be obvious.

A benchy slices well ;) disable slowdown for overhangs and you’re good
