Under extruding only on the back of the buildplate

Posted · Under extruding only on the back of the buildplate

I have 2 Ultimaker2+ machines, lately they both have been under-extruding when printing toward the back 4inches of the machine. (positive Y axis ). When the machines are printing toward the front (negative Y axis) the print quality is wonderful. I have tried: adjusting the feeder tension, temperature, speed, replaced the bowden tube, lubricated the filament with vegetable oil and increased the extrusion multiplier with no significant improvement of the print quality. I use Simplify3D application for generating the machine code. Any idea what would be causing this?

    How does the bend of your bowden tube look when the printhead is towards the back of the machine vs. when it is in front?

    Could it be that the bowden is a bit too long and has a bigger bend in that position causing more friction?

    Dosn't explain why it would happen suddenly with otherwise well functioning machines though...

      • 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
