PSssst. 0.6? My other printer runs a 0.8 nozzle . I have a tendency to run thinner layers since it seems to help with warping on ABS. Bed adhesion was driving me crazy until went with PETG, buildtack with some glue stick and a bit of heat. Just starting to get back to thicker layers. That 0.8 nozzle at 0.8 layers on a spiralized 'vase setting' cranks stuff out. I'm looking at printing less infill and figuring out a an expanding foamish fill that has fibers in it for better overall physical. There are layer issues, but to me the biggest issue is the slicing and the rendering of small holes and direct measurements. Not so much a calibration thing since gross objects are spot on, but in the past Cura and Slic3r both would undersize holes.

Designing parts is my real issue. Don't do it enough to get good at it.
