Quad extruder; Crowning paths printed with wrong extruder

Post by pjr »

I have noticed this on a few occasions, but it doesn't happen all the time.

This layer of the model uses 2 extruders, T0 and T2. The small area bottom right is T2 and the larger area is t0, but the crowning path in the red circle is printed with T2.

Here's the generated GCode:

Code: Select all

Model is the 4C Adalinda by Loubie:

So far, I haven't been able to work out why the crowning path is placed where it is and I have not found how to prevent it.

Any thoughts???

Thanks in advance
