Color bleeding problem when Dual Extruding

[RomeFallsAgain]

Hello,
Having an issue with Dual Color Prints.

The print consists of a 1mm thick, round white disk that is 40mm across.
On top, I'm attempting to print several words in a different color (black for now).
Basically it's working now but one small issue remains.

On one edge of the round white disk, I get a small areas where the 2nd color has been mingled into the white.
I'm guessing that there is a small bit of filament oozing out of the black extruder and it's getting brushed off onto the white disk then melted into the white.

I'm using an ooze shield but it still occurs.

My thought is that I need to add some custom code that (just before it begins to print the black color) moves the extruder away from the print, does a wipe on the bed, then returns immediately to the previous location and begins printing.

I don't see how else I can prevent ALL oozing from the black nozzle enough to fully prevent this.

Any suggestions would be welcomed.

Are you using both Ooze Shield and Prime Pillar? Maybe adjust retraction a bit.

Hello,
I solved the problem but had to do it another way. Seems I just could not get the black nozzle to completely stop oozing. Even the tiniest amount of black shows up on pure white pretty dramatically.

What I did was split the lettering in two so that the lettering is now two models. Each one 1/2 mm thick and stack one on top of the other.

But the first model of the letters sits directly on the surface of the disc and is the same color. Then when the second (upper) model of the letters prints (in black or any color), it already starts 1/2 mm ABOVE the disc so it doesn't drag any black drool across the white disc anymore.

Long round about way but it worked.
