Different line width for top and bottom


Recommended Posts

Posted (edited) · Different line width for top and bottom

I can only find "Top/Bottom Line Width" setting, is there no possibility to set different line width for top and bottom?

It would be very useful, using a high value for bottom (like 150% of nozzle size) would greatly reduce print speed for large flat objects, but using the same value for top is not a good idea.


I generally like using higher values for speed and strength, but it's problematic for overhangs, bridges and the first top layers, so it would be great to be able to set a different line width for these.

    We introduce the following settings in Cura 5.2:

    -          Initial Layer Outer Wall Flow

    -          Initial Layer Inner Wall Flow

    -          Initial Layer Bottom Layer Flow

    But I believe your request is slightly different. 
    I can bring it up to the Print Profiles team.

    Fingers Crossed 🤞

    Hey All,


    I brought up  your issue to our process engineers.
    They suggested the following work around.


    1. Adjust your Top/Bottom Line Width to match your desired Bottom Line Width
    2. Make your Top Surface Skin Layers equal to your Top Layers
    3. Adjust your Top Surface Skin Line Width to match your desired Top Line Width 

    This is an example of a project file how it works.

      • 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
