Slicing advices

I am currently designing my own naval cruiser to print.

The first test print went way better than the second, while i use the same settings.

I am not that into prusa slicer yet ( i always used cura with a ultimaker s5).

I litterly have craters in my second model, somehow it doesnt attach well when it goes over the mazes.

Also i get the "hairy" stuff all over my model now. 

I have the printer on 215 degreece extuder, 60 build plate at start, 40 later.

0.35mm first layer, 0.3mm later layers.

floor thickness of 1 layer.


Also if i go from 0.3mm thickness to 0.15mm i do have to adjust the Z height correct?


Thanks in advance guys!

Increase infill and add more solid layers on top in the Horizontal Shells setting.

How about going from 0.3mm layer height to 0.15mm? Do i need to calibrate or does it do it himself?

RE: Slicing advices

You don't need to recalibrate Live-Z when switching layer heights. You do need to do it when swapping nozzles, moving the printer or  otherwise making changes that might alter physical positioning.

Using a lower layer height will improve vertical resolution, and so reduce the stair-stepping "topo map" appearance on sloped surfaces. It will also increase print times as more passes are required to print the same feature.

Those defects on top are called "pillowing". As @fuchsr notes, adding more top layers will help, particularly with lower layer heights. I always want at least 1-1.2mm top layer thickness. In PrusaSlicer you can just set a minimum thickness and the slicer will determine how many layers are required. Slowing down and increasing cooling can also help.

Try playing with automatic variable layer heights for a good balance between faster prints and more vertical detail where needed.
