Looks like you're designing a 3D printed plane, aren't you ? If you want to have top and bottom layers, you'll have to use "Both" mode. And as you understood, you'll have to trim the inner surface before it touches the outer wall. There's no other way.

I ran a quick test with Cura 3.6, and the result is different ! With 3.6 I don't get all these tiny moves between segment, but instead I get a "re-run" on some of the surfaces, at the end of the layer. It looks like a combing move, but combing was set to "off" in this example.

Hi guys ! I'm having trouble slicing correctly in Cura 4.5 when using the Surface mode : "Surface" or "Both" (when it applies to loose surfaces). On small curves from loose surfaces, Cura inserts small unretracted moves between segments. It does not with enclosed volumes. Here's a pic. We're looking at 1, 2, 4, 8mm radii, in surface mode, applied to loose surfaces on the left and a similar enclosed volume on the right. Is that a bug ? Did I screw something up ?

IMHO, the best option is to use Surface Mode : Surface. For this to work properly, you have to design your STL so that the text is not a solid extrusion (i.e. with a line width of 0.4mm, where each character is a closed figure), but instead a mere surface (with no width, where each character is a path). What this implies, is that you'll probably have to draw the characters yourself, and not use typefaces.

Yes, people have tested printing planes out of it, but with partial success : The printed parts are light, but obviously not as stiff as the original PLA the planes were designed for. For some, it ended in flutter and ultimately a crash. Thanks, but this post is about PA-CF... 🤨 I'll look a bit further though. Thanks for your involvement ! Fingers crossed (expect typos)

I was testing your release, and that's the conclusion I came up to 🙂 Now, I'm not familiar with software development. What's the future for these new features ? Will they be integrated in the next official Cura revision ? Sounds too easy ...

You're the man ! Downloading now ... It has a real technical purpose : it will help 3D printed RC planes designers save a few precious grams on each wing section.

Awesome, I didn't expect to see results so quickly ! Thanks very much 🙂 I've downloaded your build, I'll give it a try soon. About Z-scaling, does the attached picture help ?

Thanks for your answer ! If you take a cube filled with gyroid, its side would look like the attached image. On the left, a regular gyroid infill On the right, the Z-scaled infill => XY period stays the same, and the infill is stretched in the Z direction..

Hi guys ! First, thanks for developping CURA. I've been using it for over a year now with my Anycubic i3 Mega, with great success. I'm currently designing a 3D printed RC airplane, and I have found that the Gyroid Infill gives promising results for creating strong yet lightweight wing sections. It could almost be used as is, but to make it perfect, and make us plane designer definitely quit time-consuming custom-drawn infill structure, we would need the following features : ability to set XY offset of the gyroid infill ability to rotate the gyroid infill in reference to the machine XY axis ability to scale the infill in the Z direction, as we need the stiffness most along the wingspan Could that be part of a future release ?
