Ultimaker Cura 4.6.1

[Blaast 1]

Hi, I'm trying to slice an object on my 0.2mm nozzle for a custom 3D printer (Artillery Genius).
0.4mm nozzle and 1mm nozzle work fine but everytime I try to set up 0.2mm (or 0.25 or 0.3mm) it resets it back to 0.4mm after any change. If I try to slice it, It gets back to 0.4mm and slices at 0.4mm.

Anyone has the same issue ? I'm switching to slic3r for testing purposes but I do like very much Cura Uu

Thank you very much!
Best regards,

Thomas D

In Cura, nozzle size isn't important.  Ignore it.  Instead set the parameters called "line width".  There are several of them.  By default they are sort of controlled by nozzle size.  But nozzle size doesn't matter - "line width" matters.  Set the line widths (all of them) to match your actual nozzle size.  You can go a bit smaller - 10% smaller is fine (.36 line width for a .4 nozzle).

Oooh. Okay, good to know ! ^^
So if I set line with at .15 for my .2 nozzle and .8 for my 1mm even though the printer is set up for .4mm nozzle it should work ? Thank you very much !

Yes, exactly.

Oh - but there are 9 "line width" settings.  Type "line width" into the search box and make sure they are all the same value.
