Maintain single part Z-seam locations when printing multiple instances?
I have a part that looks great when printed by itself but not when printed in a larger batch with multiple instances of the same part.
The Z-seam is set to nearest and the part is cylindrical with nowhere to hide seams in most layers.
With the single part print the seams are hidden in the layers that they can be, and are a nice, widely spaced spiral in the layers that they can't be. With the multi part print all the seams in the layers that can't be hidden become somewhat jaggedly aligned, I'm guessing to reduce the travel of the extruder to the next part.
Is there any way to get the seams to behave the same in the multi part print, as they do in the single part print?
Thanks in advance for any help.
Objects with round surfaces are always a hard problem for Z-seaming. The default "nearest" almost always seems to be the worst option...
When creating multiple instances of an object and using nearest, the Z seam is not always in the same place across objects. I assume the slicer takes other issues such as travel between objects into account. The only way I found I can get the same Z-seam placement is to use "aligned" or use the paint-on seams tool. I usually go with aligned as the paint-on tool doesn't allow for true vertical lines (it's an open issue on github).
