Hi,
I'm using Cura 4.3. The left part has terrible looking gaps (z axis) but the right part is smooth. I've used SPIRALIZE OUTER CONTOUR + SMOOTH SPIRALIZED COUNTOURS for the right piece. Which (i assume) means that my physical printer aspect is OK but the settings that I'm using are clearly not working.
I can even see those gaps in the Cura Preview mode (2nd image). And no gaps on the 3d image (with Spiralize option).
Any hints?
