A lot of overextrusion I think...


Recommended Posts

Posted · A lot of overextrusion I think...

Hello, dear community!


I've been printing some parts with red PLA at 205°C and a 60°C bed. The flow rate is set to 100% at the calibration cube. The rubber band gun was printed at 40% flow and the Lego brick wad also printed at 100% flow, but sliced at another newer computer with cura 3.5.0. The other parts are sliced at an older PC with cura 3.6.0, but it should not overextrude this bad... I also checked the filament diameter in cura an of the Filament, but it's both 1.75. The nozzle size is set to 0.4mm and I am using a 0.4mm one. Is there anything wrong with the PC or Cura? Another Filament also overextruded, but not so bad.

    Impossible to say without knowing all your printer speeds and layer height. I will assume your line width is set to 0.4 and wall width a multiple of that, although they should not affect under/over extrusion unless there is serious variation. Are you using 1.75 filament?

    Yes, I am using 1.75mm Filament. The printing speeds are from 25 mm/s (first layer) to 45 mm/s (inner wall). The Wall thikness is set to 0.8mm and the line width to 0.4mm. I will try the other PC soon, but I dont think that it will do much. Tanks anyways!

      • 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
