Nylon oozing fiasko


I am printing Carbon reinforced Nylon with PVA as support material on two different nozzles. I have the problem that while the PVA is printing the Carbon starts oozing which leads to a lot of junk material lying all over the built plate.

I increased retraction distance but I didn’t have any success. I heard that it is difficult to stop Nylon from oozing, so is there anything that can be done to avoid this?

See the picture as a reference.

Left Nozzle: Fiberthree F3 PA-CF Pro , Temp 280°
Right Nozzle: ProFill PVA -HT, Temp 250°
Printer: Raise3D Pro2

Thanks for you help.
