I've been slowly getting my printer dialed in and it's printing pretty well now, Just trying to eek out the final 10%.
I printed this model in vase mode 100micron layer height, and I can see some kind of pattern on it. I can't really feel it with my fingers but under the right light you can clearly see it. My printer is a D-bot corexy machine with 1.8 degree stepper for xyz and extruder. I have everything set to 64 microstepping currently. I am using a titan extruder in direct drive.

you can see a circular type of moire on the rounded corners of the vase and some smaller moire in other places. Ignore the small horizontal lines, I think my reel has a small kink in it and possible causes some uneven extrusions along those lines.
Any hints would be helpful, thanks!
