color1.stlcolor2.stlcolor2.stlI have 2 models I slected different extruders, along with dual extrusion prime tower.

When slicing it wants to only use extruder 1. Cura 4.11.0

If build plate is exrtuder2 I get this, otheriwse just 1 color and it doenst prime tower.

Any help would be apprectiated. Thank You

    I don't see a definition file for your "-2E" printer.  Did you get a definition file from TronXY?

    I ask because I could load the model from the 3mf file but Cura didn't like your printer.  Using my own dual extruder definition the preview looks right and the gcode looks good also.

    I used the X5SA pro 400 profile and added the 2nd extruder in the definitions so that I could have 2 extruders. If I override extruders setting I can a print a model with either extruder using Cura.

    I believe I also tried a custom printer and saw same visual problem with Cura.

    Tried custom printer again and I did get visual to work. I will test. Not sure what could be wrong with the Tronxy def?

    The definition file has to include the extruder train.  This is from the "Tronxy_x" definition and it looks right to me.

    "machine_extruder_trains": 
        {
                "0": "tronxy_base_extruder_0",
                "1": "tronxy_base_extruder_1"
        },

     

    Your "Extruder 1" file has two errors.

     "metadata": {
            "machine": "tronxy_x",
            "position": "0" ---------------this should be "1"
        },

        "overrides": {
            "extruder_nr": { "default_value": 0 },-----------------and this should be "1"

     

    When Cura loads the two extruders it looks like they are fighting for Position 0.  I'm guessing that's why they work separately but not together.
