After a lot of tinkering and cleaning, I have still not managed to remedy the issue that can be seen in the image.
I am consistently getting poor quality printing at the same layers, to the same height, across all of my prints. The rest of the print is fantastic, however all of the prints experience the same poor quality, at the same height.
My suspicion is that it must be to do with the z axis somehow, however I haven’t had any success yet. I have also thought that it might be that the bed temperature is too high? I am printing in HIPS, and using the recommended temperatures specified however.
Any help would be most appreciated!
