Nozzle printing "in mid-air" when sliced.


Recommended Posts

Posted · Nozzle printing "in mid-air" when sliced.

I'm not really sure how to explain what I'm seeing.


I use Cura 5.0.


When I slice some models the generated g-code tells the nozzle to print in mid-air outside of the bounds of the model itself. This causes a TON of stringing.


But I don't know what setting to change to fix it or even why it's doing it.


This never happened in Cura 4.x

    A couple of example files would help.

    Load a model with your settings profile that causes this and then use "File | Save Project" and post the 3mf file here.  It might be helpful if you would also post one of the "bad" gcode files.

    Settings like "Lift Head" and "Wipe Nozzle between Layers" can have this effect.

    This one is with "Wipe Nozzle Between Layers" enabled in your 3mf file (it's in the Experimental section).



    And this one is with it disabled.




    I suggest you always start out a Cura session by using the  Setting Visibility tool (to the right of the Setting Search bar) and set the visiblity to "All".  Sometimes you need one of these settings ("Remove all Holes" and "Make Overhangs Printable" are favorites) and then forget about it and they remain enabled and your next project is wonky.  If a setting is out of sight it's out of mind.

    I actually had the wipe nozzle between layers enabled.


    I disabled it and re-sliced and I think it's working now.


    I'm reprinting now so we'll see how it goes but I think it should be good now.


    TBH, I'm not even sure why I had it enabled in the first place.


    Thanks for the help.

      • 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
