That is incorrect. The problem is only with one extruder. Adjusting restart distance may fix the one extruder, but the other extruder will then over extrude...
Ostojo, see my posts at http://www.forum.simplify3d.com/viewtop ... rrol#p3877
It sounds like it is related to your problem. It is as you say, it does not restore the retract done on tool 0 after switching back to tool 0.
It might go away if you unselected "Only retract when crossing open spaces".
The crappy thing is that I showed this problem to Support, before I found the answer, and Support told me that there is no problem as nobody else has complained. In actuality nobody complained because support does not listen and the users must find their own solution. And that was 3 versions back. And still not fixed.
