Hello. I'm having a reaction problem. I've tried all calibration suggestions. I'm using duramic pla plus filament. I've run multiple everything. I can't figure this out. Please help. Cr-10 smart with octoprint. Upgraded extruder and Bowden tube. Thank you

    I'll take a wild guess and say you will end up between 5.5 and 6.5.


    Besides the retraction distance have you adjusted the speed?  Faster isn't always better.

    Your printing temperature makes a difference.  Cooler will not string as much.

    Within Cura's Travel settings are "Retraction Minimum Travel" and "Max Comb Distance with No Retract".  Both need to be set to a distance that is shorter than the distance between the towers but greater than "0".  That might be why those 4 models look so identical - maybe there weren't any retractions.

    If you haven't done so - turn off Z-hops.  They can create a string when the head lifts and the nozzle will pull it to the other tower.

      • 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.
