Cura makes trouble (double line) with small surface object (or big nozzle)

Recommended Posts

Posted · Cura makes trouble (double line) with small surface object (or big nozzle)

I wonder if anyone can comment why Cura can't fill a thin wall with just one line between outer shell lines. It is always drawing two lines, back and forth. To make things even worse, when coming back with INFIL line, it doesn't reduce flow at all, even though there's totally no room for another line. Same problem is related to TOP/BOTTOM line. Cura just have to finish line by returning over it, with full flow regardless if there is space for another line. INNER LINE is making the same problem. Even if I use COMPENSATE WALL OVERLAPS, Cura is trying to add some dots and pieces which are actually not missing (but in some internal calculation I guess  there are microns missing), ruining print which would be perfectly good without it. After spending hours trying to adjust as many parameters I could think of, I found a solution in Prusa slicer. Prusa automatically adjusted filling line width/flow  and made instant excellent print. I would like to stay with Cura, to keep more adjustments which Cura brings with plugins and various settings, but this project is doomed in Cura. Please tell me, am I doing something wrong? Project is in the attachment.  Thanks!


Filament is PLA 1.75, Nozzle 0.8.

    Even if just "Fill gaps" is used, Cura produces some scattered lines, messing up the form. I can’t comprehend why reduced flow line (Compensated Wall Overlaps) has some “bubbles” along the path, reminds me on messed up PID controller, especially on a curved path. Nozzle goes around touching some points of the line, without much influence, except extruder/filament flow disturbance.       

    The best result I got with halved inner wall thickness. But then extruder flow can’t be regenerated in time to properly start full sized outer wall.

      • 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
