Version

1.34.1.24

Operating system type + version

Windows 7 Professional x64

Behavior

When building with "avoid crossing perimeters" enabled, the head travels to multiple points outside of the envelope of the print. In some cases it departs from the print significantly.
The problem is not present under version 1.33.8.

  • Steps needed to reproduce the problem
    Slice a part with all boxes checked under "Quality (slower slicing)". This might work with different settings, but that is what I've used.

  • Expected Results
    (I used Repetier-Host for the display because I couldn't figure out how to display travel with slic3r preview):
    Results with Slic3r v1.33.8
    goodtravel

  • Actual Results
    Results with Slic3r v1.34.1.24, with the same settings
    badtravel

Is this a new feature request?
No

 - better shrink (do not do all polygons in one go but per expolygon), now can be used for growth & shrink
 - with multi-region, apply growths even if no hole growth
 - stop pre-clip growth, it's a mess.
Next step is to do all that in one pass to avoid some problem with big growth/shrink
