Avoiding printed parts - dual color

[Marcos T 1]

Hello,

 

As can see in the picture, using dual color, if the noozle do not avoiding printed parts, colors unwanted mix in nozzle ooze getting a bad result,

 

What can I do to solve this problem using cura 3.3.1?

 

I already tryed combing no skin without success.

Z hop help me a little bit but it is not a valid workaround.

 

Any help please?

Hi,

 

And did you try the combing to avoid all? (You can see in Layer view the blue travel lines to see if it has an effect or not)

Hi,

 

Yes, that was my first config. with no result at all.

Is that a brim inside your prime tower, or is it somehow doing 1 material on the inside and the other on the outside of the tower?

Having the same issue and I have also no solution up to now...

Z-hop is a first shot in addition to combing, but my impression is that combing or "stay inside a part" is also not working propperly.

Yes... I think the same as I can see the results even trying a lot of configs trying to avoid that problem.

 

Using single color this issue is a little bit ugly in result but is not expressive like using dual or multi colors does (my picture show how this situation can be expressive to a bad result at all, using dual colors)

 

Tks to add you reply in this topic.

The real issue is the printer needs to be aware of the second nozzle in a meaningful sense.

 

Even so it's hard to eliminate. It's just a challenge with dual nozzle prints.
