Inconsistent wall slicing


Recommended Posts

Posted (edited) · Inconsistent wall slicing

I've had this issue for a while and I can't get rid of it.

In screenshot 1, the selected layer slices correctly with one outer wall at 0.4mm thickness and one long line as inner walls.

In shot 2, it slices incorrectly with a lot of zigzags making the print unusable. It even puts holes in the print.


Designed this testpiece for different widths and back in Cura 3.5 och 3.4 I belive, it was wlicing fine.

Tried changing line width and nozzle size and Compensate Wall overlaps, and all other settings.


I've attached the generated gcode, stl, and Fusion360 file.

    Not entirely true.


    The Cura developers are working on improving the wall gap filling and thin wall printing.


    In the meantime you could try one of my builds that has a completely different implementation of those features and, generally, works a lot better. You can find my builds (Windows and Linux only, sorry) at https://www.dropbox.com/sh/s43vqzmi4d2bqe2/AAADdYdSu9iwcKa0Knqgurm4a?dl=0.


    Hope this helps.
