The new "Infill/perimeters overlap" function seems to equate a value of 0% as a 50% overlap.
In other words, an overlap setting of 50% will position the infill bead at the exact same spot as the bead from the perimeter. I would consider this a 100% overlap.
Playing around with the new function, I set the overlap to 65% and the preview functions of both Slic3r and Repetier Host showed an overlap of more than 100%, i.e. the infill was starting to show up outboard of the perimeter.
Conversely, an overlap value of -55% shows both the infill and perimeters still kissing each other. Some may be the result of display, calculation or rounding errors. But the two beads are barely touching, so I would consider that an overlap of 0%
I hope I explained this understandably.
Yep can confirm that.
Just printing with 25% overlap and the perimeter is allmost completally printing over the infill!
Change the behaviour of infill/perimeter overlap to handle some edge …
Okay, I changed that.
Confirmed on 1.2.7-dev also, but now differs from what @rf1k-mjh11 says:
0% Overlap - No overlap at all
50% Overlap - Almost there...
100% Overlap - Touching.
_115% Overlap_ - I think its the 15% meant to be default
