KISSlicer V2.0 Alpha Fault Reports

[derdigge]

Hello pjr

Yes, i agree. This is interesting and a useful thing, to have a sliwer loop1.
Wouldn´t it be nice to have a setting for that? It might improve visual quality.

Thanks.

Speedsetting not honored correctly. Even on big plates where minimum layertime would not affect.

I have set

Top 30 (1800)
Perimeter 40 (2400)
Loops 80 (4800)
Solid 140 (8400)

...

So 60mm/s speed is here in gcode instead of ecxpected 80mm/s?

Thanks

This is by design.

Perimeter is printed at perimeter speed
If loops is set to 2, there is only one loop inside the perimeter, so it runs at the loop speed
if loops is set to 3 or more, the loop directly inside the perimeter runs at the average of the perimeter and loop speeds

Not sure if this is Mac specific,
but,
when I d/l this:
KISSlicer_Mac64_v2_alpha_0.9.9.zip
and run it
I end up with version 1.6.3, not v2
repeatable

I have a Premium lic

I haven't checked what's in the dropbox now, but I definitely downloaded it on mac and I have v2 0.9.9, could that be that you are running the old binary?

[nurbie]

and,
like MAGIC
I d/l'd off dropbox for the 3rd time
and....
v2 is up and running!

NOW I can test some things that might actually contribute to r&d!

Apologies if this was reported before.

I'm getting some really weird stuff with v2.0 a 0.9.9 on bridging layers.
Check this out:



This is the layer that precedes it:



Checked the STL, looks fine.
No overlapping polys, no inverted normals, perfectly valid STL.

Looks like some bizarre rounding error, if i change the layer thickness from 0.2mm to 0.21mm, i.e. make it *slightly off* the height where the bridging begins, the little weirdo islands go away.

I think you will find that it's a problem with the model.

KISS looks at the model at precise heights; I believe for 0.2mm layers, it is 0.1, 0.3, 0.5... The model surfaces, being made up of triangles, are not precisely flat, and when a top surface is (say) 1.5mm, some of this top layer may only be 1.4999999999mm. KISS will see the parts of the top surface that are at 1.5mm or higher and produce a layer at 1.6mm for those points.

So, when you are designing a model to be printed at 0.2mm layer heights, you need to ensure that top surfaces do not happen thereabouts precisely at mid-layer.

The model is perfectly flat.
The area in question consists of flat polys all at the same height.

(Also, other slicers are not having similar issues with it.)

Think about it - for the behaviour from the screenshots, the very vertices would have to be the only parts of the polygons "sticking out" above the layer.
Does that seem possible or probable to you?
