Posted · Filament can't push through the feeder

Hi everybody, i have a strange problem:

this morning i was switching from a PLA to a ABS filament.

everything went fine till i removed the old filament and inserted the new one...

i pushed the filament a bit so the feeder could grab it and the feeder started pulling up the matirial...only to stop a few millimiters later

after trying several time, i noticed that after the filament is grabbed by the motor wheel it make a little turn and it miss the hole that lead to the bowden tube

the filament is straight and i tried with other filament but the problem remain

what could cause the filament to "turn" and how could i fix it?

Thanks in advance. :)

    If the filament is oversize then it may have trouble getting through the gap between the drive cog and the idler wheel (bearing). You would have to back off tension. If the filament has a tight curl then it's possibly just getting hung up somewhere.

    I would recommend a switch to Robert's feeder.

    ...or the variation on it which I actually use.

    Not only is it easier to tweak the tension on this feeder, it's also great for quick filament changes: you can manually poke the new filament into the bowden tube before closing the tension arm, so the problem you describe simply couldn't occur.

      • UltiMaker Cura 5.3 stable released

        UltiMaker Cura 5.3 stable released

        ArunC posted a topic in Ultimaker Cura,

        In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!

      • Here it is. The new UltiMaker S7

        Here it is. The new UltiMaker S7

        MariMakes posted a topic in Official news,

        The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
         
         
        So what’s new?
        The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
         
        The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
         
        The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.
         

         
        The UltiMaker S7 also includes quality of life improvements:
        Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more  
        Curious to see the S7 in action?
        We’re hosting a free tech demo on February 7.
        It will be live and you can ask any questions to our CTO, Miguel Calvo.

      • UltiMaker Cura Alpha 🎄 Tree Support Spotlight 🎄

        Cura Alpha With New Tree Support 🎄

        MariMakes posted a topic in Ultimaker Cura,

        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
         
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
