About layer height in prusa slicer
Hi all.
First question: Let's say we have an object 10mm tall with 0.2 layer height, then the slicer will split into 5 layers. What happens if the object is 8.5 or 9.5, I think it will round it. However, what happens if the object is 9? The slicer split it in 5 layers or 4 layers?
My second question. I can modify the height of the first layer. However, Is it possible to modify another specific layer height, and only one, at a certain height?
Thx very much.

If you have a 10mm tall model sliced at 0.2mm layer height, you will get 50 layers
If you have a 9mm tall model sliced at 0.2mm layer height, you will get 45 layers
If you have a 1.0mm tall model sliced at 0.2mm layer height, you will get 5 layers
If you have a 0.9mm tall model sliced at 0.2mm layer height, you will also get 5 layers (Rounded up)
If you have a 0.89mm tall model sliced at 0.2mm layer height, you will get 4 layers (Rounded down)
You can change the layer height of one or more layers, using a Layer Height Modifier
See the image below
this is a 0.9mm tall model, sliced at 0.2mm layer height, BUT I have used a layer height modifier for the middle layer
the layer height modifier is set to 0.1mm layer height. so the net result in your model would be 5 layers thick and 0.9mm thick (NO ROUNDING)
If you look at the corners in the picture, the bottom layer is slightly recessed from the other layers (this is caused by Elephants' foot compensation)
i have used colour change by layer to hilight the thinner middle layer.
I have enclosed a project file, below (It's a zip file, so you will need to open the file to see the contents)

RE: About layer height in prusa slicer
Thx very much for taking time to explain it so well and for the example, so I can check it much better in the slicer!!! This is what I want to know!
BTW ehm.... yeah I was thinking in 1mm height, not 10 xDDDD. Well saw!
RE: About layer height in prusa slicer
Yeah,
I guessed you had a Brain burp... on the 10mm.
i hope the info, helps,

RE:
When printing mechanical models (most of what I do), I tend to use the variable layer height tool to make sure that my horizontal surfaces are at the designed height instead of being rounded up or down. Unless I want to use organic supports...
Hopefully organic supports will finally support variable layer heights at some point by using their own layer heights independent of the object as regular and snug supports currently do. But that is a separate issue to this thread. 😉
