I'll guess and say you have your Zseam location set to "Random".  Those blobs are something else though.

My next guess is that the printer/processor isn't keeping up with the gcode flow and those are stutters.  The nozzle has to stop for a split second while it waits for the next command and those stops will leave a little blob.

In the Cura Mesh Fixes section check your Maximum Resolution.  It should be around 0.4 or 0.5.  Smaller values allow really short line segments to be generated in the gcode so it takes a lot of lines of gcode to move the nozzle 1mm around a curve.

You could also try the ArcWelder plugin.  It converts the little line segments into curves and makes them G2 and G3 commands that the printer calculates as arcs and circles (kind of - they will still be line segments but subject to the Minimum Chord Length setting in your firmware.)  Not all firmware supports G2/G3.

    Hey @bp781,


    Thanks for your report 👍
    Those are some biiiig blobs on your zseam. 
    I think it's probably related to those settings, or to retraction settings.


    Do you have a project file for us? It contains the printer and settings we need for troubleshooting. 
    To save a project file go to File -> Save project.

      • 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
