Quality decreased


Recommended Posts

Posted · Quality decreased

Hello dears,

I am a new user of Ultimaker 3 extended for prototyping in my engineering activity. Unfortunately with the last parts which I printed, I remarked that the quality is decreased: I found that the first layer is not uniform (see the 1st pic) some dimensions are not accurate (shift of 0.3 or 0.4 mm) and also there are some points where material is accumulated (see pic. 2)

I want you to know that I am using Cura 3.2.0 with recommended print setup, 1st extruder is PLA with print core AA 0.4. the second extruder for support is PVA BB0.4

Thanks in advance for advices.

      • 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
