Tips for printing coextrusion tri-color filament
I just got my first spool of coextrusion filament, (tri-color filament), and have a little challenge with controlling the color change.
As tri-color filament goes, the color should generally change when viewing the print from different sides.
However I get rather abrupt color changes in Z as well, which to my eyes, rather ruins the effect.
I'm not sure if it's the extruder changing direction, or the filament that is twisted on the spool. This is the first print from a brand new spool.
I have the setting for slicing mode set to Regular.
Anyone have any suggestions for how to prevent these sudden color changes?

After several days of printing, and closely monitoring the filament on the spool, it looks like it is the filament that has a slight and occasional axial rotation.
I'm using tri-color coextrution PLA from Eryone.
The winding on the spool looks really nice, almost Prusa spool quality winds. and the filament prints really well. So really hard to complain.
But every now and then the filament appear to be rotated axially, introducing these abrupt color changes.
I know, that it must be extremely hard to manufacture these filament in such a way, that a axial rotation is prevented, while the filament is cooled and spooled.
As there is nothing the slicer can do about that, and I'll close the question.
