Posted · Switch sequence of extruder in dual extrusion

Hi!

I have a two material object.

One material is used as a text layer and needs to be printed first in the first layer.

Cura always starts with the first extruder. So if I invert the materials the text layer would be printed second.

I could physically change the filaments but that is inconvinient.

How can I tell Cura to start with the second extruder?

Thanks!

Please clarify.  What kind of printer do you have?

 

More importantly - did you create 2 STL files?  You can assign which STL file goes to which extruder.  Did you do that?

    For clarification.

    I am using a Ultimaker 3 with dual extrusion.

    The printed object in question consists of two STL files. One file is assigned to the first extruder and the other to the second extruder.

     

    The problem in this case is that one file is a text, which is also embedded by the other.

    When I assign the text to the first extruder it will be printed first in the first layer, which is what I want.

    But if I assign the text to the second extruder it will be printed second and the result is not good. The settings in Cura are exactly the same.

    So the question is: Is there an option in Cura (or a hack) so that the printing will start with the second extruder?

    I've got exactly the same question. Of course the two objects have to be exported separatly to have different extruders assigned to each.

     

    The question is how to tell (force) Cura to start with the extruder that draws the text, and not the surface surrounding it. 

     

    When my UMS5 first draws the surface, and then tries to fill inn the text, the text shows up blurry. I find no place to switch this sequence.

    You are not supposed to have one STL file overlapping the other.

     

    Anyway make note of the setting in Cura "Alternate Mesh Removal".  Read that description for that feature.

     

    Also it matters which order you load the STL file.  So remove both and load them in the opposite order - this may help you.

    Loading order! I’ll give that a shot. 
     

    (I use object B to make a cut-out in object A. Then exporting both separately and subsequently merging them in Cure. They should then only be adjacent, not overlapping)

    I have tried it with different loading orders in the cura versions 3.6.0 and 4.4.0, but it always starts with the first extruder.

    Also the order of the assignment of the material/extruder didn't change that behaviour.

    Following procedures (1-3) yielding to identical routings:

    1) a) Load textlayer-object

        b) Load other Object
        c) assign textlayer-object to the second extruder

    2) a) Load other Object

        b) Load textlayer-object
        c) assign textlayer-object to the second extruder

    3) a) Load textlayer-object

        b) assign textlayer-object to the second extruder

        c) Load other Object

    OK I found a solution/hack:

    I cura under "Build Plate Adhesion" add a "Skirt" using the extruder you want to have for the textlayer. This material will be printed first for the skirt and therefore first for your textlayer.

    I was able to change the order in "buildplate adhesion extruder" and set it to extrude 2 instead of 1.

    Thx for that hint.
    I was searching for a solution to that aswell without switching materials / extruders.
    Seems you can even set "Build Plate Adhesion Type" to "None" after you chose the extruder you want to start with first.
