Hello guys.

First of all, printer is calibrated and working well on all tests.

At manifistation of this bug I though it's problem with negative angle of legs(pic in grey plastic ABS).
But later I've noticed it's not neative angle issue(with one leg ) it's looking good) but this is place where hotend travels from one leg to other leg.
It bring too much plastic and I got wraping there.

I know, there is Simplify3D is a option "Use random start points" but.. as many of you know Simplify crashes down each time I checked it

So, no I think I can solve it by reatrction settings.
The what do you think guys ? What I need to do to fight this horrible wraping ?

P.S. Printer is Felix 3.0
I've try ABS, PLA, any temps, any flow rates, printed it with support and without it.

First of all, random start points works absolutely fine. I've never had crashes with it. Are you using some really old version of S3D? Make sure you are using the latest 2.2.2

Second, it is not uncommon that the overhang side of a print will look worse than the non-overhang side. Your issues look more like standard overhang problems. You can get better results by lower the layer height and sometimes even by decreasing the extruder temp by 5-10 degrees (since more heat causes bigger issues with overhangs). You may also want to try aligning all your start points in different locations to try to rule out if that makes a difference. S3D has a nice options for that too.

Not so easy as it seems

As I told before I've printed many forms with heavy angles. And everything is fine.

Look at that example - 4 legs with different angle printed at once.
(last leg - most nagles is that I need)

So, 1 and 4 (!) is perfect. No any artefacts.
2 and 3 - wraped.

That's why I insist it's not common "45degree printer problem". It's something strange with more than need felament on retraction or something like that.

1) Did you try random start points? what was the result?

2) Did you try aligning all of the start points to a specific location (such as the non-overhang side of the legs, in this case, probably near 0,80,0)? what was the result?

This would be a good way to make sure it is not due to start point placement. I would think that always starting your layer on the non-overhang side of the part would help (option 2)
