Hi. Just came here and haven't found anything similar.
So I'm having this weird surface on printing in regular mode. But printing in Vase Mode shows that there's no issues with hardware (printer is ok, anyway).
In this example it is black PLA at 190 deg, printing speeds are 40 - 70 mms (tried different, doesn't matter). Straight lines are better. The issue seems to be in inconsistent movement during printing. I can see it with eyes, the nozzle moves by the even arc, movement should be consistent because there's no deviations, model is cylindrical (using 3MF files, no insane triangles like in STL). Anyway, at random places nozzle moves faster than in other places. No consistency or correlation with geometry. No dependency on printing settings; only in vase mode it prints nicely and evenly.
Printer: Ender 3 Pro with SKR Mini 1.2 DIP + 2208 UART; TFT24. PLA at 190 deg.
Cura 4.6.1
