Cura 4.3 z-axis wall quality

[rookie7799 0]

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?

Turn off coasting?

I just found out why ... Z Seam Alignment was set to "Random"; switched it to "Sharpest Corner" and the walls are now smooth. Haven't tried printing yet though.
