What happened?

Vase mode creating weird artifacts or "seams". appears as gaps or misaligned layers in the gcode previews.

currently, the vase mode is crude:
it continue to slice layer by layer
then it will change the z based on the distance % on a layer. So when it's at the top (end of the layer, it is at the same height as the next one, but not at the right x & y if there is a slope.
I tried to move the seam away from slopes, but there is no start position that won't push you into a slope here. So it's an unavoidable artifact of the current slicing algorithm.

@supermerill please check that project with the nightly, i can't slice it, empty result.

@robustini
if you put G1 Z0.01 after the START_PRINT in the custom start gcode AND you uncheck the use_relative_e_distances, then the gcode viewer works again.

I don't why yet, I'll look into it.

G1 Z0.01

Thanks for the tip, that string after the start gcode was enough for me, the other option that is flagged or not in my slicing does not make a difference.

I have noted this bug as well. When I went digging for what / why I found something interesting. This is a known bug in PS for several years now. prusa3d#2841 This is from 2019, there is a 'fix' listed but it's not a good fix at all and it does mess up the model. Here is the same bug in Orcaslicer SoftFever/OrcaSlicer#431

any news about it?
