Hi friends,

My question is is why my Ulitimaker2 and Ultimaker2 ext is not printing well at layer height 0.15mm and 0.2mm ? at this low quality i get a very bad printing i never get it before like this king of printing quality from my Ultimaker.

while i am using latest version of cura 2.3.1 and also i updated my printers with latest firmware.

my printers working very well only at normal qality 0.1mm layer height.

please let me know how can i fix this issue?

    Have you tried increasing the temperature? If you're trying to extrude more filament with the old style feeder, increasing the temperature can help reduce the amount of resistance you're seeing. Any photos?

    I have also started having problems with printing at 0.2 layer height.

    I used to be able to switch between 0.1 and 0.2 without problems or having to change settings but now 0.2 has become unusable.

    I have tried different materials from different manufacturers and cleaning the nozzle in case this was causing the under extrusion but it has not solved the problem.

    I have also started having problems with pillowing at 0.1 on models that printed OK previously.

    In view of the fact I have had other problems with Cura 2.3.1 I have reverted to using 15.04.3 however this has not helped either, which leads me to think that something that has been changed in the firmware (which I have not put back - I don't know if that is possible) is causing the problem.

    The fact if it's an UM2 or UM2+ is VERY important for this problem. As the UM2 has the problem where the teflon piece slowly deforms, causing this exact problem. Requiring a new teflon piece.

    The UM2+ is much better armed against this problem.

    Thanks Daid.

    Have only seen your post recently but have now put a new coupler in my UM2 and this looks like it has fixed the problem.

      • 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
