No Retraction with 2nd use extruder on first layer

Recommended Posts

I am having an issue with my Ultimaker 3 whereby whichever extruder is activated 2nd does not retract on the first layer and makes lines all over. In the example below I used Cura 3.6.0 and mostly default settings. The Pink (Extruder #2) activates first to draw the skirt and then does all the pink letters and hearts while retracting properly. Then the Black activates and after making the prime blob, drags a line to the skirt. [I have found: WHICHEVER EXTRUDER ACTIVATES SECOND, DRAGS THIS LINE...SOMETIMES DRAGGING THE PRIME BLOB WITH IT AND RUINING THE PRINT] . Then as the black material moves from one spot to the next, it drags an ugly black line across the pink. How do I stop this from happening? I have tried turning Combing Mode to 'Not in Skin' and to 'Within Infill' and the problem persists. I have not tried turning Combing Mode off yet because it would add extend the print job from 6 hours to 8 hours. Any other suggestions?

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
