Crazy stringing and head positioning

Hello.

So today I printed a Superlambbanana for a friend, happy to share the model it only took me 10 minutes to build it, and this is what appeared:

SLB1.jpg?psid=1

SLB2.jpg?psid=1

Please ignore my bad nails.

As you can see it's very stringy, and the legs are not attached to the body. This could either be the head position incorrect, bad GCode, or the thing moved about - it came off the bed very easily.

I was printing .065, 30mm, 210. Two models at one. Think I'll try 20mm at 190 next time, however the second model came out fine, apart from the string. And the overhangs look dreadful.

Cheers.

    It looks strange. I think I would have to see it from another angle. My first thought was that one of your axes slipped and needs tightening and that it slipped only once on a particular layer except that The "tail" support didn't also slip.

    Before printing it again, check the "bad" layer carefully in Cura layer view.

    Although maybe you got some underextrusion?

    The stringing isn't too severe but you can probably eliminate it. You might want to experiment with retraction distances on a test piece first.

    I think the base came partly loose on that one print that looked messy. Add more brim, and more glue, to keep it stuck.

    It looks like you probably don't have retraction turned on, or at least not set up right, which is what caused all the stringing. Make sure it's turned on, and then in expert settings, set the retraction distance to 1.5mm, the minimal extrusion to 0, and turn off combing. Set your travel move speed to 250mm/s.

    Other than that, the print looks pretty nice, so I wouldn't mess with the temp or print speeds much.

      • 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.
