Slender SLOWdown. Secret feature slows down slender items terribly

[Mlogue9 3]

I have looked and looked and looked and looked and can NOT figure out what the F is going on. It happened with 4.8, now with 4.9b and still does it. One would think it was "small features print speed" modifier but no. I carefully set speed for the whole model only to find it reset it to how it saw fit.

 

See screenshot - it previews like it's going to print 9mm/s. Hell I'll print it to see what happens.

If you will use File | Save Project and post the 3mf file somebody will take a look.  If you can't post that model (if proprietary) it can be a similar model - but it must have the settings for the problem model and with the mesh modifier set up the same way.

Perhaps it's the minimum layer time feature?

Perhaps it is. I didn't think to look in cooling - poor placement as it's actually speed related to cooling. Thankx
