A10M wrong colors during dual extrusion print

[Jakub]

Hi,
I am trying to do double colored traffic cone. I have A10M with original print firmware marlin 1.1.8
So far I have used ultimaker cura 4.1.0 with cura profile by jdharris from thingiverse. Problem is that insted of black color there is a mixed grey color.

Then I tried Repetier-host 2.1.6 with printer settings downloaded from this pages. In this case bottom of cone is printed correctly with white but then suddenly color changes to black. From this point colors are swapped (black/white) and instead of white there is grey.

Do somebody know what I am doing wrong?
Single color printing is without any issues.

thanks Jakub

Hi，you need to set all the temperatures the same, for both extruders including stand by temperature; then makes sure that the nozzle switch retraction speed and distance is the same as normal retractions, for both extruders. And you need to clean the nozzle regularly. It seems that your printing temperature is a bit high. try reducing it by 5° before printing.
I hope this can help you.
