[Feature request] Ironing whole layers

[kusiak]

Version

2.3.0 Beta 3

3D printer brand / version + firmware version (if known)

What 3D printer brand / version are you printing on, is it a stock model or did you modify the printer, what firmware is running on your printer, version of the firmware #s Oryginal Prusa MK3 firmware: 3.9.1

Behavior

• Describe the problem When ironing top surfaces slicer ignores areas that will not be visible this is a problem as on some models this induces a lot of retractions, movements and blobs left on top surface.
• Steps needed to reproduce the problem Take any model with lots of symbols on top surface
• Expected Results Provide an option in the slicer settings for ironing the whole top surface, at once, then print next layers on top of the smoothed surface
• Actual Results Lots of symbols on top of a smooth surface Nozzle movements for every little inside space

Is this a new feature request? yes

I'm happy to provide more context if needed

It would be a huge improvement in ironing quality. Also ironing a bit more beyond the perimeters would help.

I wrote a longer explanation on how this could work in #9451, with a minimal threshold for continuous ironing (closed it as the concept is essentially the same)

Not seeing any additional comments in a very long time. Any feedback from the devs on this possibility?

Skipping ironing on an area when another layer will be printed there is especially bad on the Prusa XL when we are dealing with mixed nozzle sizes. Just having the ironing pass go across 100% of the surface and then printing the next toolhead's output onto a clean, ironed surface would yield dramatically better results.
