If I made no mistakes, the 5.1.1 does only Iron the upmost Top Layer, as the 5.1.0 Ironed all Top Layers.

V5.1.1 doesn't change any of the ironing behavior. It should still iron any exposed top layer (not just the last layer of the print).

I just setup several prints here to confirm, and I can clearly see the ironing toolpaths in the preview, even in middle layers of the print that have top surfaces.

If you're still having trouble, perhaps you can post your factory file?

Thank you for the answer. So it seems I have done mistakes , have to re-check the settings.
