you are right, factory file would have been handy, I included it now with this reply.
Outline overlap of 80% did wonders, bit thanks man. Don't really know why... probably because the inner space between the perimeter is less than the nozzle width...
Outline Overlap This value will dictate how far into the perimeter the infill goes. If this value was 0, the infill would start of the perimeter and not overlap at all. At 100%, you would have complete overlapping. Calibrating this value, I would say the average value I find that works well is 30% for the printers I've used, but it does vary.
