Cura choosing weird path for printing gears

For some reason cura decides to print the outer teeth as little islands before joining them with the hub, any way to fix that?

Same problem as in this Github discussion : https://github.com/Ultimaker/Cura/issues/15056#issuecomment-1689206800

 

Should be partially solved in version 5.5. I say partial, because in this case, if the print order is better for the print, the wall print order is no longer respected, which will certainly lead to other comments. 

 

5.X -> 5.4

 

5.5 or use the executable mentioned in the post

Selecting wall ordering 'outside to inside' might solve the problem.

Well I tried changing wall order, but the print still fails due to it making random lines then goingsomewhere else

Have you tried printing the gears individually (i.e. their own file, one at a time)? I know Cura can get some weird ideas when it comes to printing separate models at once.

 

Also if you could provide the gcode file (the one that Cura produces after you slice something and is what the printer actually uses) that might help because then we can see it's actually getting the printer to do, not just how it's being sliced.

I'll try that after school today.
