Thanks for the hint! Indeed v5.2.2 worked smoothly in that respect.
Were you able to create a model without loops, i.e. which can be printed in "real" vase mode (no retractions)? I have played with inset parameter, but I was not able to create a smooth model. There are always loops which require nozzle to move to that part and print it. Please attach a project, if you succeed. Thanks in advance!
If hole in the model was created artificially by you then it is fine. I don't need it, unless it fixes some issue or side effect 😃
