Re: 4.1 Vase Mode Defect

That is common issue that S3D lives with for years. Search for topics "vase seam".
It was in S3D 3.0, and other slicers have it too. The only one how can print without it - Cura with z-seam fix option ON.

Re: V4.1 Wipe issue

Same here. Spent a day to find it, as it appears only on exact speed/settings and model. Here is my gcode, you can import FFF profile from it into clean S3D 4.1 with default settings and it should be reproducible, at least with provided benchy model: https://www.dropbox.com/s/uyq4sfshhvw20bd/3DBench...

Re: Smooth perimeters speed slowdown in S3D 4.0 as it was in

I did small test to compare the difference.
Printing speed is 80mm/s & 50% for the perimeters, 3 perimeters, 0.2mm layer height.

The results are "almost" the same, but in some places 3.1.1 have better quality than 4.0.0.

Re: Smooth perimeters speed slowdown in S3D 4.0 as it was in

a easy programming "radio" button or check box option, possibly even a selection of how many perimeters use the "external perimeter speed" In my understanding, one check button with the "Use old style perimeters speed" text, and another speed calculation formula in app, taken directly from S3D 3.1....

Re: Smooth perimeters speed slowdown in S3D 4.0 as it was in

A read of this might help avoid embarrassment.... http://physicscatalyst.com/article/common-mistake-average-speed-calculation/ Numbers in my calculations is wrong, but the idea is simple - when inner perimeter prints faster, it will take less time to print the model. Also quality influence should b...

Re: Smooth perimeters speed slowdown in S3D 4.0 as it was in

The actual numbers isn't important, the point is that the average speed is higher with v4, so total print time will be a tiny bit faster, not slower. v4.0: (40+50+50)/3 = 47mm/s v3.1: (40+50+60)/3 = 50mm/s (faster) In case when perimeters have 25% speed with max 60mm/s (my default setup in S3D 3.1)...

Re: Smooth perimeters speed slowdown in S3D 4.0 as it was in

> With v4 you will have speeds of 40 - 60 - 60 (starting from the outside).
Actually, 40-50-50 - internal perimeters print speed is not max speed. You can see the difference on the image above.

But if you need to print vase without the seam ...

Re: Vase mode seam

Sorry, my fault, I fixed model orientation and scale. I did many tests with different models, and this bug is visible on most of them. Here are more examples: 20248043_137190820203658_2610335406051285424_o.jpg 20280430_137190113537062_4950405342443788356_o.jpg 20248062_137189946870412_38155173903420...

Re: Smooth perimeters speed slowdown in S3D 4.0 as it was in

>except increase print times ever so slightly With three perimeters size it should decrease print time, not increase. On four layers quality should be better, as outer lines will be printed slower and accurate, while interanal perimeters - fast. Also, when speed is different, it may reduce waving re...
