Wriggly walls

Hi again. 


I'd be very pleased, if you can help me once more. 

Two-three weeks ago my printer startet out of nothing to print the walls quite wriggly (see Image "1").

My Ultimaker 2 has the newest Thinker firmware (V19.03.1) installed.

I've printed PLA with 210° / 60° at standard speed. 




Nicolinux had in 2016 a similar Problem, described in the flowing threat:

Because of this, I also tried to switch of the build plate heating. 

When I switched if off, everything was great (see Image "2"):



But without the build plate heating it looses the adhesion. So I tried the PID auto config with 5 iterations. Which gave the following result (see Image "3"):



All the previous prints were printed with 0.2 mm Layer hight.

I then accidentally tried to print one with 0.1 mm Layer hight. Which resulted in a print without any wriggles, even though the print bead heating was activated.  (see Image "4"): 



How is this possible? I'm getting wriggy walls when I print with 0.2 mm Layer hight. But with 0.1 mm Layer hight everything is OK. Or when I print with 0.2 mm Layer hight but stop the printing bed heating, also every thing is all right. But the adhesion is very bad. So I need this combination of 0.2 mm Layer hight and printing bed heating. 


Thanks for your advice.

    So I finally figured it out. 

    I tried the flowing: 

    • Setting 8/16 Jumer
      • Not influence
    • Loosening the long screws of the printing head
      • improves the print but it has still wriggles
    • Greasing the z-axis
      • no improvement
    • Changing heat bed temperature
      • no improvement
    • Changing extruder temperature
      • improves the print but it has still wriggles
    • Switching of the fan
      • no improvement
    • Auto adjust the PID of the bed and the extruder
      • Even worse wriggles
    • Tring different PID settings
      • The wriggle pattern changed, but no actual improvement

    After many try and error cycles I finally came to step 26... 


    The solution was: 

    • Exchanging the temperature sensor, Olsson Block, Noozle and this White thermal piece. 
    • So test 26 was successful:
    • IMG_8394.thumb.JPG.1e5c4c3dc4c828f448367a49d2731542.JPG

    Of all four replaced parts, I think it's just because of the PT100 temperature sensor. As I intended to replace the temperature sensor, it wasn't possible to get it out of the Olsson Block. Therefore I replaced all these different parts.

      • 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.
