Cura 3.6 with UMS5 Line Width Per Layer Consistency Issue


Recommended Posts

Posted · Cura 3.6 with UMS5 Line Width Per Layer Consistency Issue

Hey guys. I was wondering how cura slices the first layer of the print. Dimensionally, it's not corresponding to the line width I have chosen and the overall length which to lay the line. On top of that the line width from this first layer, changes in every subsequent layer. To illustrate, I'm printing a 35 mm x 12 mm x 4.2 mm ( x,y,z) rectangular prism, with line width set to 0.8 mm. In cura, the first layer only slices 12 lines when I expect 15 to account for y-dimension length ( 0.8*15=12 mm). The layers after the first all have 14 lines, which is closer to the 15 I expected, but the fact that the number of lines has changed is confusing me. This causes the bottom of the rectangular prism to be fatter then the rest of the part. Even though it only prints 12 lines for the first layer, they are significantly fatter, definitely more wide than the input 0.8mm.  For my application its really important for all the layers to be exactly the same. I couldn't seem to find any settings in Cura where I could make sure the number of lines per layer stays consistent. 

 

Any assistance would be greatly appreciated!

    The line width can be set individually for all line types available.

    Take a look at the manual: https://ultimaker.com/en/resources/52340-quality


    Amongst others there's a setting called "Initial Layer Line Width", it's set to 120% in the default profiles (take notice of the tooltip).

      • 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.
