Сoasting is disabled. Retraction of extra prime amount - 0. On the one hand, your advice about "retraction of extra prime amount" looks logical, I will try it, thank you. On the other hand, it's strange that this problem occurs on cylindrical parts when part is alone on the bed

unfortunately, I already use "inside to outside", so the reason is something else

I encountered an unpleasant problem of "holes" at the beginning of each layer. The problem is often encountered on the Internet, the community gives a lot of advice, but none of it helped me. The problem occurs either on cylindrical parts or if there are several parts on the bed (if there is only one part, it will print without these "holes", even without a hint of them). Some of the tips seemed reasonable but did not help me, for example: Reduce your "Retraction Distance". I use 1mm on my Taz 6. Disable "Retract at Layer Change". Disable "Retract before outer wall". Change which "Z seam Alignment" (Shell section) you are using. I tried to experiment with the length and speed of the retract, but I only change the shape of these holes and do not solve the problem.
