Complete Individual Objects -> crash

[juckendesAuge]

Description of the bug

The problem is how Prusa Slicer arranges the objects for "Complete Individual Objects".
Due to the unsorted automatic arrangement there was a crash. Unfortunately, the printer ran over an object and thus affected the cable harness behind the extruder. In the worst case there was a cable break.

Suggestion:
Sorted arrangement of the printed parts, as seen in the video.
This will at least reduce crashes with "Complete Individual Objects". Even if you have changed the printer, the greatest possible distance to other objects is always maintained, which reduces a crash.
Here I would also recommend to raise the heating bed temperature by 5 degrees Celsius, because in the outer areas of the heating bed the 60°C are not reached.

Unfortunately I have to resort to videos for this as well, since I can't describe it with a screenshot.

Arrange and crash detection for sequential printing was improved in PrusaSlicer 2.9.1-alpha1. I believe it solves this issue. Your feedback is welcome. Closing.
