Hi all,

So I have an Ultimaker 2+ and I recently tried the Colorfabb Bronzefill PLA material. The print failed just before the end, and I don't know why. I decided to change back to the ultimaker material, but it wasn't extruding. I tried to use the option to Move material as per the instructions, but it wouldn't extrude. So then I tried the Atomic Method, and after about 8 attempts of heating up to 260C and cooling down to 90C, I eventually got a residue free (none of the bronzefill material) conical shaped end on my PLA. However, it's STILL not extruding. Any ideas? I'm going to swap nozzles to try that, but after taking off the 0.4mm nozzle, I can clearly see it's blocked. Is it advisable to try to unblock using a pin or something? Or is there another solution?

Any advice greatly appreciated! The bronzefill material looked great, but if this is what it's gonna do to the printer each time maybe I should drop it.

Cheers,

Seán

    Update: Changing the nozzle didn't work either - it's still not extruding. I can see the feeder moving it as much as it can when I try the Move material option so I know it's feeding the material well enough... Any ideas? This is driving me crazy.

    Okay, - user error strikes again. I hadn't pushed the Bowden tube down quite far enough after the atomic method. Did it now and it works again. Hopefully this helps someone else with the same problem at some stage.

    Bowden not actually inserted into teflon, so filament hits the top inner side of teflon and refuses to go in? At 3D Solex they have a teflon which has a bigger entry-chamfer so the bowden more easily clicks into place...

    Yeah, that was exactly what was happening, thanks. Having owned this machine for just a few days, I'm not ready just yet to upgrade it, but that looks interesting!

      • 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!
          • Thanks

      • 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.
