Odd behavior on settings on overlap for wall count with One at a time sequencing enabled

[Mutrised 1]

Hi,

 

I'm facing what seems like a miss behavior to me.
I have a piece to print, which I need to be more robust on one side, so I added some infill density and some perimeters on this side, usinde de settings by models with overlap.

 

What seems odd to me is that I set the wall count to 2, so since my base slicing setting is 2 walls, I expect 4 walls on this side.

 

This is what I get in "print all at once" mode for print sequence setting, but if I set one at a time (even if my piece and the block used to modify its settings are grouped together), I get twice as much wall added than expected (if I set 1 I got 2+2 outer walls, if I set 2 I get 2+2 pairs of inner/outer walls so 6 in total).

 

"How about setting only 1 wall so you get two then" you may ask... I have a bunch of these pieces to print, so I'm tweaking the print so it print faster. I have set the outer wall to print at normal speed, but inner wall print quite fast, so having 2 outer walls added instead of one inner and one outer make me loose some time..; Multiplied by the number of pieces, it's not negligible...
And anyway, I don't understand why this feature would behave differently depending on the selected print sequence...

Does anyone have something for me on this ?

 

Thanks

Tristan

I'll respond just so you know this has been seen but I'm not the right person to comment.  One of the Cura Team members (@nallath?) will need to chime in.

I will say that I can duplicate this.  It appears that the Infill Mesh is getting an extra set of walls on the inside.  It's particularly odd that there is an outer wall sandwiched in there.

It shouldn't behave differently. Could you create an issue on github?

Sure I'll do it, thanks
