Small holes in external perimeters
this weekend I found a new printing problem for me. I was printing a cylinder with a concave character (for 0.2mm in the cylinder). After first printing, around character was perfect but at the character area I saw some small hole, like the part of layers wasn't print. So I started resolving problem with extrusion multiplier, but wasn't any better. The following steps were desreacing the retraction lenght, decreasing the external perimeters printing speed and printing with hotter temperature, but nothing better.
MY PRINTER: Prusa I3 MK3S (kit) SLICER: Prusa slicer
MY SETTINGS are in photos.
Layers and perimeters:
The last picture is showing my last test, it was with convex character, but the same problem.
Thanks for helping me
