Zig Zag infill behind inner perimeters

[worthy sedge]

Wondering what the zig zag is behind my inner perimetrs in some places (behind Overhangs?)
Is this default behavior or do I have something selected to make it happen?

The project 3MF would be better so we can see all the settings you are currently using.

It is a lot of plates but it is doing it universally Let me save it and attach

I've seen this issue before and figured out how to fix it, but can't remember off the top of my head. It's a simple settings change though.

[worthy sedge]

It is printing well this way but it is adding a bit of time on the plates

[crimson gulch]

is it plate 1? which layer number?

[safe lion]

And which Orca version exactly?

[safe lion]

It shows as Internal solid infill and is meant to act as an anchor point for Internal bridging. As I recall this was a new feature in v2.3.1. Some setting will change it to be a straight line instead of this zig-zag.

But as I remember it was not very intuitive.

[midnight token]

it's the zig zag backing up the walls, right?

[safe lion]

Yeah

[midnight token]

it's due to ensure vertical shell thickness, and happens in sloped regions

if you set it to none, for example, it goes away

[safe lion]

Interesting. I could have sworn I had seen it in models with straight sides that still had it even with that feature off. Guess I will have to go back and double check some things.

[worthy sedge]

Makes sense... I will have to try it both on and off and see how it effects prints. If I dont need it I could save some time on large plates

Thank You for the assist...greatly appreciated, new slicers are definely a learning curve

[midnight token]

if you set 'detect narrow internal infill' it will change it to simply be an extra perimeter or two printed at infill speeds

I have had cases where 'ensure vertical shell thickness' needed to be set to 'all' for prints to come out nicely

[midnight token]

(this is what I recommend, btw)

[safe lion]

Ah! That's probably what I was thinking of. Nice job!

[midnight token]

thank you

[worthy sedge]

Doesnt that infil small triangles in corners instead of using monotonic lines everywhere?

[midnight token]

in some areas, yes

but it won't affect top or bottom layers

[worthy sedge]

I had that on and it seemed sloppy to me....guess its my linear brain, lol

I want to revisit that one for sure.... Many thanks for the clarity.

[crimson gulch]

slicers have a steep learning curve when you start to get into all the settings

[midnight token]

it is a little weird and I remember thinking the same thing when it was first added. But it makes the prints faster and doesn't affect the external quality.

[safe lion]

It's supposed to help speed up printing, but the results seem insignificant...unless maybe on very intricate models where a lot of solid infill travel moves could be an issue.

Fixing this line issue is a bonus though, so that's something.

[midnight token]

replacing the zig-zig with a straight line reduces print time fairly significantly, especially on older printers with lower acceleration

[worthy sedge]

I can't complain.... I am getting some nice results so far

[crimson gulch]

if you want the curves to be nice try variable layer height

[worthy sedge]

Still have a lot of inefficiencies in my settings I am sure.

[worthy sedge]

Never played with that before

[crimson gulch]

as both the curved surfaces are bout the same height as each other it would be perfect

[worthy sedge]

If you see any other "mis-settings" in my profile feel free to make me aware. I definitely got a bit more to learn with Orca.

[crimson gulch]

there are about 750 settings not sure many know what they all do😆

[safe lion]

Definitely not, haha. Still learning new things about it almost every day.

[worthy sedge]

True

I have been able to get pretty decent prints from it so far for the short time I have been using it
