arti has made, to me, a very valid suggestion that has....so far...fallen on deaf ears!!!
An extrusion multiplier of 110% is also shouting at me as being wrong!
And a third point from me....the picture ion the first post indicates that arti is right to suggest coasting...….
What I see from the photo is that on the perimeter extrusion, the extrusion is okay apart from either the very beginning of the extrusion, or the very end of the extrusion. There is nowhere else visible on that single photo where there appears to be a deficiency in the amount of plastic. This says to me that the extrusion multiplier (as was when the print was done) is not that far off optimum....and that there is an issue with the ooze control settings.
You will need to revert to these previous settings and reprint the part....and observe what is happening. Is the "gap" in printing happening at the start or the end of the extrusion path around the perimeter???
If its at the start then you need to look to increase the amount of plastic being extruded at the start of the extrusion. This means reducing the retraction distance a little and adding some Extra Restart Distance. This will reduce the amount of retraction and add a little extra plastic when the extruder retraction is reversed. If retraction is off, then try turning it on with minimal retraction and a little more restart.
If the gap is at the end of the extrusion, then your coasting needs to be reduced. Coasting is where the extrusion is stopped to allow the extruder pressure to die down. If coasting is off, then you do have an issue with extrusion....and I suggest upping temperature a little and calibrating your extruder feed and checking filament diameter. A multiplier value of 110% doesn't sound right!
