Combine infill  

RE: Combine infill

I suggest you check the slice preview more carefully.  With it set to 2 like you have it then the infill will be printed double height.  So as you advance up the preview layer by layer you should see the infill laid down once for every 2 perimeter layers, they end up at the same height though as the steps match up. 
There's a maximum it can do when it comes to filament flow though so I'd expect it to be clever enough if you set large combine infill values.  Practically speaking I wouldn't expect anything above 2-3 to be viable anyway at 0.2 layer heights.  Its certainly more noticeable when you drop layer heights to 0.1, at that layer height I can set combine at 4 and it works.

I set the value to "3" with a layer thickness of 0.2. But every time I look through the layer, it grows and fills

RE: Combine infill

Set it to 2 and you will see that it updates the infill every other layer.  Change your layer height to 0.1 and you can set the combine infill to 4.  I suspect its obeying the maximum layer height setting defined under the Printer>Extruder.

At 0.2 layer height then every 3 layers would be printing a 0.6 thick layer which is outside the range defined under your extruder.

Thank you, you're right. Unfortunately, with a layer width of 0.4 and a height of 0.2, this parameter does not work even if you change the maximum layer height.

RE: Combine infill

Yeah, I would like to add that I can't see this parameter have any effect either. 
I know how it's supposed to work, but I can't get it to actually do anything
