Netfabb area over filling problem.

Hi All,

I can't seem to be able to get decent filling with Netfabb, it seems to consistently overfill top and bottom layers.

 

If I wait it out, the nozzle smooths the "junk" after a few layers, but there must be a way to prevent this from happening.

Please advise.

Thanks

Note: print quality with RepG is flawless.

    I'm using 1a : Standard Quality Filled Object with corresponding 1: PLA Standard material and a 2.5 mm Fill Spacing.

    However the problem is in the upskin and downskin layers of the print, before the Fill Spacing setting kicks in.

    I was able to fix the problem by switching to the hatching pattern fill pattern (from a spiral pattern), which effectively reduces the number of passthrough on a single point and consequently reduces the build ups and prevents the formation of "mounds" at the corners.

    I can finally print with Netfabb!

    Thanks guys.

    Hi Benoit,

    I use Netfabb, but I've never bothered with Standard Quality. I've never been able to get half-way decent prints on anything other than Ultra - but with Ultra the prints are utterly amazing. I've increased the speed on my Ultra profile so I can get beautiful prints in the same time as the regular standard profile that still look amazing. I've even managed to tune those up to 200% using real-time tuning in Replicator-G and still achieve a nice result.

    Cheers,

    Troy.

    Troy,

    Thanks for the advise.

    Yes the Netfabb standrard quality is much lower than what RepG outputs, however the toolpath algorithm makes it much nicer and easier to post process.

    Once i'm comfortable and confident with Netfabb, I'll move up to Fine and Ultra (i'd like to have a good comparison between them all)

    Have you (or anyone) been able to thin down the layer thickness from 80 microns to 20 microns (like in RepG's Very Fine setting offers) ?

    Have you calibrated at all? Or, if using the latest version, switched to volumetric and put in the correct diameter for your filament?

    Yes it is calibrated, but i'm using 4.9.0 (on MacOS)

    I played with the "Width Factor" parameter on the "Build Style->Region Definition" section and was able to fix most of the problems, and I'm now pretty satisfied with the "standard quality" setting.

    I still need to work on improving the upskin finish but so far so good.

    Here are some photos.

    Thanks for the help!

    Update: problem solved, all Netfabb built-in profiles work flawlessly.

    My problems:

    1. Using MacOS Netfabb 4.9, I switched to Windows using Netfabb 4.9.2 (volumetric).

    2. Using USB to drive the print (the animations and information updates caused the hot end to pause and ooze for seconds at a time while it sent the data to the computer), I switched to SD cards from the Ultipanel

    3. Operating the Ultimaker in a non air-conditioned room (here room temperature is 27-32 C), I placed it in the direct path of the air-con outlet which makes the PLA filament harder and less prone to deform in the feeder mechanism during during Fine/Snake areas where the rate is low; it also makes the print cool down faster so there previously printed material cannot be displaced.

    Here is a sample of the "standard quality" profile (with hatching instead of spiral filling)

      • 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.
