Walls separated

Posted (edited) · Walls separated

I need some help... I’m in 3 goups on fb and nobody has any useful insight.. (aka is the bed level, nozzle to close) YES THATS NOT THE DAM PROBLEM... sorry just sick of people not reading the problem and just throwing crap suggestions... 


so the problem is my walls all have nothing between  them from outside wall 1 inward 2,3,4 but 4 is fused nicely to the infill. So all the walls are flexing like stacks of paper. 


I have even increased the flow of the inner walls to fatten them up hoping to fill the gaps but nope.



Glass bed is clean, level

nozel height is good

pid autotune calibrated

esteps are calibrated

flow is calibrated 

Ironing is on for everywhere

    Your flow is at 45.8% which is about half the normal flow.  So having gaps between the walls as big as the walls makes perfect sense.  If you want to increase flow try 110%, not 45.8%.

     Thanks for checking it out... after modifying the machine with longer cables to relocate components like the motherboard, the values the board needed to see were wayyyy off.. that’s why I had to go through pid autotune first, then esteps and lastly flow. The default value of 93 (I think) for flow was tremendously over swelling a test square I modeled 1.000”x1.000” 0.020”wall thickness. The 020 designed wall was printing aprox.040  And blustery. the correction formula brought the flow  down to 45.8 to print as designed. That being said I did in the print in the above pics make the interior walls print with a flow of 100% and only the outer wall the 45.8 for precision however the gaps remained. 

    Even if I adjust the outside wall flow to 100 the gaps will remain and I only loose dimensions accuracy. 

    I just don’t understand why I either can’t adjust the wall to wall distance to be 0 or have it iron across it to make it one.

    Just to continue from above about my flow setup at 45.8. Here is a pic of 2 test cubes I printed 1.000” x 1.000” x 0.020” wall. 

    the ugly one on the smoothest area measured 0.045”thk with the default flow setting of 100 (mistaken in the above post about 93 as default that’s for esteps) 


    The better one measures 0.021”thick uniformly.

    So apparently this is a cura slicer problem. Last night I changed from 4 walls that I was trying thinking it would add additional strength to the part but created these non adherence walls.. back down to 1 wall (1outside and 1inside) and it’s printing fantastic again.


    so my question is why do you have a option to create more walls regardless of how many you select  of the software can’t seem to stitch them all together like it does with the default walls? 🤷🏻‍♂️ There’s gotta be a configuration to do I just can’t figure it out after 2 weeks..

      • 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.
