wall finish (look vibrated) and small blob in corner


Recommended Posts

Posted · wall finish (look vibrated) and small blob in corner

Hi all,

I am trying to go deep in using the Cura software with my Custom delta. (based on a Tevo Little monster)

My Printer have a volcano hotend (original D3D) . Material ASA Appollo-X

I customized more or less everything. The hardware should produce nice work. And some time it happen so good. But some time the settings are difficult to be found.

So here I am.

1)On only one side ,  where the nozzle start to print (red square) ,the finish have no sense (for that side only). Tried temp from 220 to 260 , fan hight and low etc etc. It seems an excess of extrusion. But if I lower the flow things make even worse. After all the rest of the object is very good so...boh.

On the same side  but where ne nozzle don't start the level (green square) , the finish is perfect. (actually I'm trying to print the infill before ... let see what I'll get)

The other side are all good.

2) When the nozzle turn happen some blob (yellow square). But this can be related to the close retraction. So I should investigate in that direction.

Under the yellow square there is the support for the hole.

 

Any suggestion where to look in the settings?

 

Thanks for all the contributions 😉

    Not sure what's causing these issues but try printing at half speed and also at 1/4 speed for a few layers - just to see what happens.  Your printer should allow you to set feedrate at 50% while printing.  And then also try 25%.

     

    With PLA 240C works but not if you want nice looking prints.  Stick to closer to 210C or even 195C.  Every printer is different so I can't say what temp is best.

    Thanks gr5 😀

    I'll try also the way you suggest.

    On the box of the ASA they suggest to print between 235 and 255 degree. I tried very low temperature but unfortunately the layers didn't fuse for guarantee the optimum solidity of the object. I mean, i tried to break the object and I discovered that the layers where not fuse properly.

    Print the infill before make the thinks look a little better but give dimensional problems. So the solution don't lies there.

    I'll continue to investigate and I'll report what I discover...

      • 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.
