I'm still learning on 3D printing and have just started on vases. As such I'm using the spiral/corkscrew/vase checkbox on the Layer tab to look to avoid any seams.
I still seem to get seams though, which do show in the print preview. Having played around with a few settings, the only way I seem to be able to get them to disappear is by unchecking "Force retraction between layers" in the Advanced tab.
If this is the valid solution then great, but otherwise what is my problem please? I assumed that the Vase checkbox would handle any settings that would limit it (it even gives a pop up to warn this), but if it's not the case then I'll take note.
Cheers.
