A Question About Infill

[rsterne]

I had a problem with some gaps in the shell of my printing at the default 120 mm/sec on my Ender-5 S1 with PLA, so I slowed it down to 80 and that cured it.... However, I notice that the infill still has some gaps.... I am using Cubic....



Is this normal, or should the walls of the infill be complete surfaces?.... If so, what would you change to get that?.... and what difference would it make?....

Kinda hard to see by the pick but you can try to increase your infill line width and slow down infill print speed. I double the line width and run speed down to 30.
Your milage may vary.

I looked at the pic when I got to my computer and is it the infill or the top layer that is incomplete? If it's the top layer you can increase the layer count on the top.

There is no top layer, that print failed part way through when I tried to change the filament without knowing what I should have done....  It is the infill that you can see the gaps in....

Ok I would increase the infill line width  and Slow it down more

Bob,

My first question is more of an assumption -- that you are using Cura on this?
Do you have the Setting Visibility where you can see everything?
I'm not sure if Cura by default shows you all the print speeds individually, or just the main "Print Speed"
If you set the main Print Speed to 80, the infill speed is set at 80, but the walls, tops, and bottoms get set at half that speed, 40.
If you're already setting them individually, I'd slow down the infill speed a bit more.  Sloppy infill isn't necessarily a big deal, just depends if you prefer a faster print or stronger fill.  I think there's an infill called "Lightning" which is intentionally fast and sloppy...

It’s difficult from the picture to tell. What is the infill percentage set to?

I was using the Creality Slicer (Cura based).... For this purpose I don't really care about the infill.... At 15% it is still strong enough, even with the gaps.... I can see the layer-by-layer preview, and I found the "all" menu, where I can see (and adjust) every item separately.... I just wanted to know what it "should" look like, and I assume that is what you see in the layer-by-layer preview....

Yes the preview is what it should print like if everything is set right. A few infill flaws usually won't  hurt anything.
