Trouble benchmarking

[HauntedMaestro]

I've been having a bit of a struggle for the last few weeks and was hoping someone could give me some insight.
I installed E3D V6 HotEnds which are great! Although I've been printing with my CubeX Duo using KISSlicer for quite some time. I hadn't really needed to adjust many parameters.
Since installing the HotEnds, things like the sample files on Cubexupgrade print exceptionally well. But when i print something like a spool holder with a 12.5% infill, it gets quite muddy. It seems to happen on slicing areas that are small. I'v attached images from KISSlicer of the areas i'm talking about and images of the print.
Any help would be wonderful.
Thanks
Shaun

Hi Shaun,

From your pictures it looks like a lack of internal support in your print.
You could try to increase infill to 30% and wall thickness too. 10% give you some long gap between infill and the cubex doesn't print in hight speed so plastic is falling between infill wall.
You can also setup more loop, it will give you less sparce infill so quicker print.

Thanks very much for the help Hugues. I will attempt these adjustments.
I'm still having a hard time understanding what a Loop is exactly. I've been reading the
KISSlicer manual but can't exactly wrap my head around it.

Cheers and thanks again.

Hi Shaun,

Loop are turns done following the shape. But it means two things, if you 've a close sphere, and setup 2 loops, the printer will do 2 turns and then doing infill, but if you have a bowl it will do 2 turn from the external surface and 2 other turn from the inside surface. In all case if loop doesn't match skin thinkness and are inferior than skin thickness kisslicer will add sparce infill.

Hope this short explanation helps !

It does greatly. Thanks so much for the help

Cheers,
Shaun

You generally want to set your number of loops (times extrusion width) to be greater than your skin thickness.

With a single loop, and your skin thickness settings, the external loop is not substantial enough to handle the zig-zag skin thickness passes.

Skin thickness applies to the bottom and top layer thickness, but is also applies to the vertical surfaces of the print.
