`Hi there

Is there a possibility in Cura to complete sections of a print before others. I would like to finish the rocket fins sequently to obtain better results.

This is basically my second print and it is done with vase mode, as you can see from the photo the last portion of the rocket fins are affected by stringing/travel?

Sorry i am still a novice to this :)  also is there a way to control print speed for sections as well??

 

Thank you!

    That looks pretty good.  A little work with an Exacto knife and some miniature files and it's done.

    The answer to the first question is no, because Cura goes layer by layer.  It won't make changes in the Z to finish one area and then drop back down to bring up another area.  It wouldn't know if it was going to crash into something already completed.  It does have the ability to make adjustments if you were to bring the fins in as a separate part.  The body could have one speed setting and the fins could have a different speed setting.  If you have the actual model you can do that.  If your working with just an stl file then I don't believe that it's possible.  What you could do is add an M220 line in the gcode file at the layer where the body runs out and only the fins are left.  If the printer was running at 100% feed-rate you could add M220 S75 and knock the speed down to 75% (or whatever works).

    Stringiness can be a function of temperature (too hot), retract distance (too little), material, or even color.  Silver PETG can get pretty stringy while black isn't near as bad.

    "That looks pretty good" is an understatement IMHO !!  I've never seen a part printed in "Vase" mode with any details like your fins.  Congrats if this is only your second print.  Perhaps you might try printing a more convention part, but specify zero infill to make it hollow with 3 walls, .2 layer. 6 bottom layers, no top layers, with a .4 nozzle.  Unfortunately, unlike vase mode, you will end up with a "Z" scar somewhere on the side of the part.

     

    I print mainly models of plastic bottles and they are printed hollow.  Don't know if any of this will help you.

    Thanks for your replies!

     

    I did found a way to clean the print using stitching feature in Cura.

    By the way i used 1.0 nozzle with 1.6 layer width and it looks and works out fine for my purpose.

    It took 6.5 hours to print a +- 400 round x 400 height  🙂

    Will post another photo once perfected!

     

    Cheers!

      • 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.
