Random under extrusion only in middle of print, perfect top and bottom

Posted (edited) · Random under extrusion only in middle of print, perfect top and bottom

Hello,

I've been using my UM2+ for months without issue until last night. A print started out great and looked like the first several layers printed perfect, as did the last several it seems, but in the middle there is a great deal of under extrusion going on. The model in Cura 2.3.1 looks good, no red in the x-ray, and the layer preview looks good as well. But why would it really under extrude in the middle but not the end? I can't figure out if this is a hardware or software issue. I have the g-code available to preview. Attached are the Cura settings, the layer preview, X-ray, as well as images of the final print. I scaled the part to 125%, used the basic Normal quality default settings, but changed infill pattern to Tetrahedral, and enabled supports only touching build plate.

Does anyone have any ideas if this is hardware or software?

    I tried printing a known working g-code file which failed as soon as it started to do the infill. I troubleshot using this guide ->

    A visual Ultimaker troubleshooting guide

    http://support.3dverkstan.se/article/23-a-visual-ultimaker-troubleshooting-guide

    Which pointed me to having a clogged nozzle after I checked that my filament wasn't tangled or snagged. So I performed the atomic method and it's now printing perfectly.

      • 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
