While printing and sometimes afterwards I see those little scratches I can call it but I doubt it's caused by nozzle scratching the print. What are these and how to get rid of them?  (Mostly seen near the edges of the print)

    Layer height: 0.1 or 0.2 mm i cant remember but I use both
    Extruder temp: 235
    Print speeds: all around 30-45mm/s
    Flow %: I am guessing 100%? I didnt find it nor change it in my Cura settings

    Hi @andrulonis ok as you do not mention it then I assume you are using PLA and if that is the case then you are printing way too hot and you are over-extruding. Drop your temp. to 195 which should be OK. You can even try 190 for a better result, especially if you are using 0.1. If you are using 0.2 with 45mm/s you might need to push the extruder temp to 200; all printers and filament are different, so one cannot be too prescriptive, what works for you is best, but not 235 🙂

     

    If you are using ABS then your temp is probably in the ball park but I have. never used ABS so it would be wrong for me to guess what is going on.

      • 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.
