Cura 5.3.X : Limit the maximum line width ?

Recommended Posts

Posted (edited) · Cura 5.3.X : Limit the maximum line width ?

Hi to all


I am printing a water tank in PETG, but getting issues with some sort of stringing, in fact same issue as combing in the walls with PETG, though combing is set to within infill.


In fact there is an over extrusion due to the line width used by Arachne engine : 1,08 mm for a 0.6 mm nozzle with PETG !


The tank's walls are 2.4 mm thick, in order to have 4 perimeters of 0,6mm line width. Line settings for walls are also set to 0.6mm. But instead I have 3 perimeters when sliced....






As a result, print is a bit messy giving some leakages of the tank.


Currently extrusion has been well calibrated (100% flow, filament diameter checked, ...)


Is there a way to have 4 perimeters printed ?


Thanks for your help

    This post and the link it contains to a Reddit post explain why there is no Max Line Width.


    A lot of settings can effect how many walls you end up with.  Horizontal Expansion, Hole Horizontal Expansion, Outer Wall Inset, etc.

    Post a project file and someone will take a look.


    This box has 2.4 walls and Cura is set up with a 0.6 nozzle with 0.6 Line Width.

    @GregValiant Thanks for the post and link.


    Since that post Cura has evolved a bit and some settings are now obsolète in 5.3.

    But I have understood the principles.


    I will play with the minimum line width in order to match the desired number of perimeters and get back to "normal" extrusion conditions.

      • UltiMaker Cura Alpha 🎄 Tree Support Spotlight 🎄
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
