Ultimaker 3 Extended Drags filament

[kenny 2]

I've been having an issue that I'm not sure what is causing it. When I start a dual extrusion print extruder 2 (whether it's printing PLA or PVA) will drag filament from the prime blob across the print bed to where it starts the print and then there is also some stringing from that extruder during the print. extruder 1 has no troubles with either of that. Extruder 1 had generic PLA and extruder 2 had Ultimaker PLA. I have retractions enabled as you can see in the pictures. any ideas. I'm pretty new to Ultimaker and Cura. Thanks for your help

You could consider disabling the prime blob which is currently the default in Cura.

But the overall string print makes me think you may have left a BB printcore in there for the silver material, if so try it with an AA printcore.

Thanks for the response

    I do have the AA printcore installed for both extruders, but I will try disabling the print blob.
