AA 0.25 Nozzle - 0.1mm layer height only?

[Crash55 1]

I have a lot of small models that I need to print and wanted to use my AA 0.25 nozzle but every time I swap to it in Cura my layer height is locked at 0.1mm.  If I swap to the AA 0.4 nozzle I can select 0.06mm lay height.  Any idea what is going on?

It just means the Cura team have not made a preset profile for that nozzle and layer height, you can still print at 0.06 layer heights if you wish, just create a new print profile and under quality adjust the Layer Height setting to 0.06, making sure your line width settings are still set for a 0.25 nozzle at 0.23.

I can also tell you something about the rationale; With a 0.25 nozzle and 0.06 layerheight, the steps that the feeder would need to make get really, really small. So small that it will start to cause artifacts in your print.

So as much as we tried, we really couldn't get the 0.06 profiles to work in a way that was anyway better than the 0.1 ones, so that's why they didn't make it (because it does take a lot longer to print)

So is there any point in using the AA 0.25 vs AA 0.4?  

 

I need to do some high resolution prints and am trying to get the best results.  Should it be AA 0.25 at 0.1 or AA 0.4 at 0.06?

I would say it depends on which direction you need the resolution, in x or y then use the 0.25 core, if you need it in z then you can also try the 0.4. In my opinion there is not much difference between 0.06 and 0.1, I don't think you can see any differences.

 

I printed a model of an Aztec Calendar with thousands of details and it came out great with 0.1 and the 0.25 core.

I need to print a bunch of very small armored vehicles for a wargaming class so I think I will go with the 0.25 and 0.1 layer height.

 

Thanks for all the replies

Very small armored vehicles for wargaming might be better printed with a resin printer.

When I print miniatures, i tend to use the 0.25 nozzle.

I don't have a resin printer so not an option.  

 

I used the 0.25 nozzle and 0.1 layer height and they look pretty good.
