· Understanding settings for adaptive layers

As I see it, the "max variation" setting sets the min and max layer as "Layer Height" ± "Max Variation". Based on this, if my poor ender can only print a 0.68 max layer before the sprite can't keep up, I need to make sure "Layer Height" + "Max Variation" < 0.68mm. I could use something like 0.5 Layer height with 0.18 variation for a range of 0.32-0.68.
✅ But you could always try slowing down if you want even thicker layers.

The "Layer Variation Step size" is used to create a type of gradient between layers. Cura reads ahead to forulate an "ideal layer height" candiate and then start stepping at ± "step size" to get to the ideal height. A smaller step size will result in smoother transition but longer slice/print times as more layers are needed.
❌ It's the increments in that it will use for layer heights. For example I usually use 0.2mm ± 0.08mm with a step size of 0.02mm. This means the possible layer heights it will use are 0.12mm, 0.14mm, 0.16mm, 0.18mm, 0.2mm, 0.22mm, 0.24mm, 0.26mm, 0.28mm. It won't create a 0.17mm tall layer, for example.
If I had the step size set to 0.04mm then it would it only be 0.12mm, 0.16mm, 0.2mm, 0.24mm, 0.28mm. It wouldn't create a 0.14mm tall layer.

I think the only trigger is topograhy size. If Cura sees an "overhang" of this value it starts looking to reduce layers to smooth the edge. This is great for things like vertical threads and holes as it will smooth the surface. This is only effective when the horizontal difference between to layers is counted. VERTICAL difference is not counted (0.25mm in one layer vs 0.25mm over 5 layers in a fillet). There is not prevision to manage an averadged slope at this time.
🟡 It's the horizontal distance apart between any outside line and the outside lines of the layer above or below (which touch, anyway). For example if you had it set to 0.25mm, if you had a slope which was so shallow that each layer was 0.3mm further in than the previous layer, it would reduce layer height until that gap was closed to 0.25mm (or it hits the minimum layer height).

If you need speed alterations based on layer thickness (my poor poor ender 3) then you need to buy a better extruder or just slow the whole thing down to slowest speed for the thickest/most detailed layer.
✅ But you can go to the Cooling section and set Minimum Layer Time to however long it would take at the tallest layer height possible. This will force it to wait on shorter layers though.

Here comes Cura 5.9 and in this stable release we have lots of material and printer profiles for UltiMaker printers, including the newly released Sketch Sprint. Additionally, scarf seams have been introduced alongside even more print settings and improvements. Check out the rest of this article to find out the details on all of that and more
We are happy to announce the next evolution in the UltiMaker 3D printer lineup: the UltiMaker Factor 4 industrial-grade 3D printer, designed to take manufacturing to new levels of efficiency and reliability. Factor 4 is an end-to-end 3D printing solution for light industrial applications
