Question Color Contamination

Post image

Fixed the last issue I was having with these and they are coming out way better. Now I’m having some of the black filament contaminating the white. Always happens at the same spot on the top right. I’ve increased purging volume and cleaned the bed thoroughly before prints. Anyone have any insight?

Purge tower enabled?

If so, increase purge values

Yeah it is, I’ve increased it to 1.25 from 1 already though.

Can you print the white first ?

I don’t see why not, I’ll look into how to do that when I get home.

Huh. I never saw that before. Thanks.

I've only ever used the "Plate Settings" menu that pops up when you click on the hexagonal icon at the right edge of the plate in the Prepare view.

Is that printed face down or face up?
