Prime Tower issue

Hello everybody, is there any way to print the second color (starting at layer 29) of the prime tower on the top of the first color (ending at layer 28) in Cura? The first one ends when the second should start, but always, the second color is printed in the air (not printed at all) because the first color is printed on the top of the PT, not leaving any space for the second one. I appreciate your help in advance.

    Hey @palacinka11,


    Welcome to the Ultimaker Community 🎉

    Your prime tower should always be printing with two colors. 😮
    There shouldn't be a setting that you change to start printing that color. 

    Do you have a picture or a project file for us? 

    A project file contains the printer and settings we need for troubleshooting. 
    To save a project file go to File -> Save project.

    Hello, after a lot of comments in FB 3D printing groups I realized it should be print both color from the bottom, but it wasn't. I tried to change to extruders for the filament and then it looked like it could eventually work (PT was printed with "both" colors from the bottom). Although, new issue came out this way, which I didn't know how to solve, so I just laid it down (the printer started printing with the first color, but didn't get to second on the PT and didn't change for the printed object, so first few centimeters of the object weren't printed). Again, after I asked in a 3D printing groups, I got answer that I should change the extruders back.  Yeah, I do have a project file, the printer is Lotmaxx Shark V2, both materials were PLA from the same brand, just different colors. I will send you the file to dm.

    Hey @palacinka11,


    Thanks for sharing your files in a personal message. 👍
    That looks like a difficult printjob with those tiny details 😦


    A prime tower is there to help prevent two colors of material blending. 
    But since there is only a single nozzle used in each layer, the prime tower isn't really going to help here. 
    You could even print this on a single extrusion printer with a filament change at a certain layer. 
    This doesn't look like a bug, it looks like Cura does exactly what it's told to do. 

    But the way that your model is set up, enables you to have your logo show up on both sides. 
    I made some small changes, and now you can take full advantage of your dual extrusion printer. 


    I'll share the project file in a personal message. 

    Good luck with your prints!

    Ok, but if I print it like this, wouldn't be the bottom layer (first layer) also in two colors? I need the bottom (stand) orange and only the words blue. Anyway, thank you so much for your effort and time with this, but as I wrote in your dm, I figured it another way around. 🙂

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
