Feeder keeps reversing, won't feed filament.

Posted · Feeder keeps reversing, won't feed filament.

Hello!

I'm having issues getting my UM2 to print recently. I had some decently long successful prints (8-15 hrs) that turned out great, but for the past three days I can't get the feeder to push the material through the nozzle. I've done the "atomic" method and cleaned out any gunk from the nozzle. Additionally, I used a 0.4mm bit to clean the nozzle as well. With the bowden tube removed, I can manually push material through and the feeder will move the material, but with the two together I don't have any luck. I tuned the feeder tension-er when it was working fine, but now the stepper motor will turn 3 small turns and on the fourth it will click back to where it started. I put a black dot on my filament and it doesn't move. I had tried heating the nozzle, removing the bowden tube, moving material so it stuck out of bowden tube, and then manually feeding that in but as soon as it is reliant on the feeder wheel it just "clicks". Any guidance would be greatly appreciated. I've only had the printer since April, so I have a hard time believing I've worn it out!

    Remove the filament and cut the tip to a point. It often gets hung up inside the print head where the bowden tube meets the white teflon part. Also inspect this visually to make sure the bowden is securely sitting inside the white teflon part.

    You can try feeding manually. For example, power cycle the printer, go to ADVANCED and turn on only the print head to 180C. When temp gets there push and pull on the filament a few times - it should go through the bowden no problem (it's possible there's something inside the bowden binding the filament - that happened to me recently). Push nice and hard - about enough to lift the printer up off the table - that should be enough to get a small amount of filament through the nozzle. If that's not working - it's obviously not the feeder.

      • 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
