Hi,

After updating the firmware of my UM2+ today the automatic removing and loading of the filament comes 20 cm short, can I change this?

    Speaking for no-one else, I have to say that I don't understand. Are you saying that you snapped the filament?

    Or are you just saying that the filament doesn't come all the way out?  If this is it then I expect it's by design: push the release lever on the new style feeder and pull the filament out, which should happen easily. Try to keep the filament reel from unravelling.

    It's your second assumption, you understand correct, but...

    Before the update it came all the way out and when inserting all the way to the print head, after the update I have to pull it out 20 cm as you describe and when inserting I have to do the same 20 cm the way in, I cannot imagine that UM changed that distance 20 cm...

    The version that comes with Cura 15.04.5

    It looks like I have to be more patient and let the filament come to the print head with "wait till material comes out of the nozzel" but that's very slow.

    I still think that before the filament stopped further down the tube.

    Or just feed in more filament before you release the catch on the feeder? I have yet to fit my feeder upgrade, which may explain why I'm still struggling to imagine what the problem is.

    You have to only feed the filament into the feeder and then the feeder transports it rapidly almost to the print head.

    Then the feeder goes slow and you have to wait util filament is comping out of the printer head.

    Mine does 2/3 of the tube quick and 1/3 very slow, tonight I did the dishes while waiting for filament out of the print head.

    I think I do a ticket to UM tomorrow, it seems nobody knows the problem.

    Thanks anyway, Dree

    When loading the filament, you need to get it to reach the first clip on the Bowden before pressing the button (either let it get there on its own by the feeders action or hold the release and push it further in if your really in a hurry)

    If you don't get it that far into the tube (first clip) before pressing the button then it would be very long wait :-)

    I have the new extruder, and know the problem. I let it push the filament to the second clip on the bowden before I ask the printer to forward to the head. If I just wait till the first, the printer will timeout after forwarding and then waiting for material to reach the printhead. First I thought the new bowden was much longer, but it has the same length. The same happens when retracting the filament out of the printer, it should not need to stop way into the bowden tube.

    Now I know that it is actually not only me I adapted and now it works beter and faster.

    However it stil doesn't feel right to violate the feeder this way, I have the feeling driving a porch with a beagle engine. I wish there was an expert setting to adjust the filament travel distance.

      • Here it is. The new UltiMaker S7
        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 5.3.0-Alpha 🎄 Tree Support Spotlight 🎄
        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.
