Thanks for your tips !
Yes indeed I know 8mm is a big value that will fail at a retractation test (4 is my sweet spot) off course but I wanted to give it a try for this kind of print for the next test...
I did try just now to put travel distance to 0 but nothing changed.
I will crank up travel speed it's a good idea thanks and I totally get what you mean by "not smart enough", this is indeed true that sometimes humans are hoping to much from machines !
But I would appreciate to have a kind of "avoid travelling over previously printed part" option someday 😉 (or travelling over skirt).
Best
