Cura layer heights limits

[antiklesys 3]

What are the layer heights limits of Cura?

I used to be able to print at 20micron with Netfabb, can Cura do that too or is the slicing limit set to 60 micron? If so, is there any project to reach 0.02 layer height in the nearly future?

On the other hand instead what is the biggest layer height? 0.25 is low quality print, but can it be also 0.4?

Have you tried? I can set it to both 0.02 and 0.4 without problem. However, I personally never go below 0.06 as I think results starts to get worse again below that height (your results may vary). And also going above about 0.3 isn't the best either. You actually get a warning when going above 0.32 (the field turns yellow). Your nozzle is squeezing out a strand of plastic that is 0.4mm, imagine what happens if you try to print at that height, the next layer can't press into the first, it will be lying on top instead of being fused into the previous layer.

I was asking as Cura is brilliant and I know the printer can do amazing 0.02 prints with Netfabb, I just wondered whether they were as amazing with Cura

0.02 is no problem for Cura (it may be for the printer, or the particular material you use, but not for Cura).

I think Cura can use pretty much any layer height - I just sliced a model with 20 mm layer height. Looks amazing.

That doesn't have anything to do with "is it actually printable or not". But Cura can do it.

You probably haven't switched to Expert mode yet (Expert -> Switch to full settings). You can just put in any values you like and see if it slices (with Layer view).
