Useless moves to the corners of my object.

Do not report Prusa3D Slic3r bugs here without confirming it is a problem on a development release of Slic3r, or your issue will be closed. Development builds of Slic3r. Prusa3D Issue Tracker

Describe the bug When slicing 16 copies of a simple object, after working on each object, it seems that the print head is first commanded to go to the closest corner instead of directly to the next object.

To Reproduce load the testcubes.stl file, send to printer (disable start print), load the file and view in gcode viewer.

You'll see the moves to the corners. My real object doesn't do it on the first layer, but my test "testcubes" does. On my real print it gets worse the higher the object, on the test cubes it gets better as the layers progress.

You need octoprint to visualize the bad results. The "layers" view in slic3r doesn't show the unnecessary moves.

3D Model and Slic3r Configuration Export I also included the openscad code, to allow you to create variants if that helps in debugging. report.zip Expected behavior No extra moves between subobjects.

Screenshots

Desktop (please complete the following information):

• OS: Linux ubuntu 20.04
• Version slic3r-1.3.1-dev-92abbc4-linux-x64.tar.bz2 and slic3r-1.3.1-dev-8c69278-linux-x64.tar.bz2 (I upgraded to the latest today before reporting this) .

Additional context This started recently it seems(without upgrading slic3r!). I have "good" prints of the object where this shows up.
