Visual Defects/Artifacts on Flat Layer

[LBussy]

Greetings.

I am printing a box with a large flat surface on the inside. it also has small features which "interrupts" the flat printing and causes visual defects where the printer skipped an area and came back. I'm sure you have all seen this. Here's a picture that shows it very well:



Now I know I have some nozzle dragging, which I am working on. What I am referring to here though is the right to left artifacts that exist from the printing "skipping" areas when it hits those small features and doing only infill under them.

What I would like to do, if possible, is print those flat areas solid as if there were no features on them. I hope that makes sense. If I have a large flat area I want to print it solid in one pass and sort of ignore the face that there's a feature there till it gets to that layer. Does that make sense?

You could add a second process to define that layer as solid with 100% fill. Then you know the entire thing would be printed completely solid.

Yet another person requesting the ability to expand skins that lie under other features so that the completely unnecessary area of infill goes away. Why don't S3D fix this ridiculous defect?

I think one thing that would be nice to see is that in cases like this or where you have these kinds of things on a part that do go through the bottom layer like for screws, is that it would start filling the layer at one corner and then work its way all the way across on the first pass filling as much as possible with out a break. Problem now is that it fills in until it gets to a "nub" then it jumps to another area then comes back making unnecessary breaks in the fill. I think it would make for a better layer.

I think it already fills as much as it can before making a break. If you have a feature in the middle of the print, I'm not sure how you would fill both sides of it without causing a break...

I wasn't meaning to fill both sides around the post without a break! What I am seeing on one I did this weekend that is similar to the pic is that it would fill from the corner out to the first post then it would jump to another area to fill then come back and continue filling across rather then just keeping it continuous then fill in on the other sides of the posts.
I could post a pic with a better description later but it is more a suggestion for what I would think would help give a better surface.
Maybe it changes areas on solid fill for heat reasons? Not sure.
