Nozzle clearing

When Cura prints a prime blob or performs a nozzle wipe, it always seems to do it *immediately* before moving the print head towards the model. Wouldn't it make more sense to move it away? I've found that things that need the prime tend not to adhere so well, and the printhead routinely drags the prime blob if not into the part, somewhere that it's going to wind up interfering with the part.

 

The same thing with skirt: I've watched it lay down a beautiful line of skirt that adheres perfectly, but then it travels straight to or across the part footprint with a tiny little dangle of ooze that falls off in the least convenient part of the adhesion layer, or it turns out to be the one place in the print that it's going to string.

 

Lastly: is it possible to move the print head outside the bed? I just wonder how many prints would go better if the the head couldn't traverse one of the corners of the bed, with and then lower to { first-layer z - first-layer-width/3 } at the very edge of the bed moving - slowly - to first-layer z as it crosses up to the bed... If anything is hanging off the head, this should knock it off, and the trip along the side and round the corner should help to drag any ooze or string off the plate? (Yeah, it sounds too easy, so I suspect it's not or you'd have done it 🙂

      • UltiMaker Cura 5.3 stable released
        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
        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 🎄
        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.
