ultimaker² print qualtiy problems

Posted · ultimaker² print qualtiy problems

Hello,

though I'm able to produce usable prints, I can't seem to get the print-quality on my ultimaker² right.

Apart from the default settings, I've played with a lot of settings and followed different calibration-guides, but to no avail.

From what I've observed, it seems the string of molten filament that comes out of the nozzle is too thick compared to what comes out of other 0.4 hot-ends I've seen. Reducing the infill doesn't work though, the amount seems right.

As a result, it tends to 'smudge' on edges, making a mess of details. And the infill doesn't come out as lines with a more or less constant diameter, but as thin strings and a lump on the intersection.

I'm sure this machine is capable of more- what's going wrong? I'd upload some pictures, is that possible on this forum, or do i need a external file hoster?

    Hi! There is a gallery feature! You can find it by opening the drop down menu on the upper right where your nickname is. After uploading you can embed pictures from gallerys in your posts.

    Thank You for your answers, sorry for not being very responsive the last days.

    By infill, do you mean 'fill density' or 'infill overlap'?

    I usually use a fill density around 30%, as there seems to be a problem bridging bigger gaps when closing the top, as discribed above.

    Went down a bit with 'infill overlap', currently at 12%, maybe thats the way to go.

    uploaded some pics illustrating the problems discribed above:

    Infill thicker on intersections, stringy in between:

      • 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
