Hello,
I have been having print issues when printing anything more complex then a pipe. Below is an example, the pipe printed which looks perfect to me. But the cone is shows a lot of imperfections through. The cone is mostly mostly hollow, it is a part for a spool holder. I am pretty new to 3d printing and I am having trouble finding the issue. I have tried leveling the bed, checking the gantry to be square, and cleaning the whole extruder assembly.
I am using Cura 3.2.1 and a Hictop ( creality) cr-10s.
