Missing steps - Shifting layers

Posted · Missing steps - Shifting layers

Hi,

I'm having problems printing large items. Smaller things work well,

but when items are big I get huge shifting mid-print (up to 2cm shift on some occasions). Some times several shifts happen during one print, with just a few layers in between shifts.

I have no idea where this is coming from. The belts are nice and tight.

Any ideas how to find the source of this problem ?

    If it only and always happens with larger prints, i would also look into overheating of the motor or stepper driver.

    Do you have all the heatsinks on them, and how about the fanduct on your electronics?

    Original poster fixed the problem by oiling rods apparently (he cross posted in google groups).

      • 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
