Using adaptive layers results in thinner floor and roof #15003

Application Version

5.3.0

Platform

Windows 10

Printer

Anycubic i3 Mega

Reproduction steps

I have a model with a layer height set to 0.2mm, floor and roof 1.2mm 6 layers.

Actual results

When I slice and print using adaptive layers the slicer sets the initial and final layer height to 0.1mm and still prints 6 layers so my floor and roof are now 0.6mm and weaker than I expected.

Expected results

However, for strength and following the thickness decision I would expect that the adaptive layers option maintained the required thickness, not the required layers.

Thanks for the report and file. Looking through the Gcode it appears that the layer height steps down from the initial 0.2 and goes to "LayerHeight - AdaptiveLayersMaximumVariation" and stays there for the entire print. Not very "adaptive". Someone from the Cura team will take a look.
