I have a question regarding the duplicate-distance:

How can I change it? So that objects will get arranged with a distance of 2mm instead of 6mm (for example).
I tried to do it manualy in the config.ini, by changing the value of the duplicate_distance, but it didn't work.

Any ideas?
Thanks for your help

In 1.2.9 what I do is just duplicate first, then manually arrange in 2D view.

Thats the way I do it normally.
But it really sucks with more than 10 Pieces

The question is what do I have to do, that slic3r does it automatically.

by the way
