Posted · How to improve print quality back to v3.6 (CR-10 mini)

Printer: CR-10 Mini

Filament: Hatchbox PLA

Problem: Cannot get Cura v4.x to match v3.6 print quality (v4.4 is the closest which is good news)- See Image.  I have tried to match the settings/profiles as much as I can but maybe I'm missing something.

Goal:  Meet or exceed print quality of Cura v3.6 with the latest release of Cura (v4.#).  v4.4 is closer but need help in how to improve further. I want to use the updated software as opposed to sticking with an outdated version.

 

Background

I had been using Cura 3.6 for quite awhile and felt like I was getting pretty good print.  I'm using a CR-10 Mini and most of the settings were default with the exception of nozzle temp and bed temp.  I then upgraded to 4.x at some point at which time my profiles didn't carry over.  I in-turn "recreated" the profiles as best as I could.  I recently started printing again more regularly and noticed my quality wasn't what it used to be (v4.2.1 vs v3.6).  At one point I thought it may be the filament and that it had taken on moisture, however when I printed a gcode file created by v3.6 it printed fine.  So next I updated to the 4.4 beta and while it did significantly improve there were areas that still were not as good as the v3.6.  I have included a comparison of 3 pcs I have printed in the last 24 hrs using the same model and as close to the same settings as I'm capable of (essentially the default 0.2 draft PLA settings, only changes were nozzle temp of 205 and bed of 40).  Interestingly I feel the base and spiral of v4.4 has the best quality and I am satisfied with it, however the horses head is still better on v3.6 because v4.4 has "bumpy" areas instead of smooth lines.  While v4.4 is definitely improved over v4.2.1 in this area, I would like to try to get it back to the v3.6 level.  That being said I'm at a loss as to what would be the cause of the "bumpy" lines and what settings to tweak to try to improve it.  Any advice or recommendations would be appreciated.

        UltiMaker Cura 5.3 stable released

        ArunC posted a topic in Ultimaker Cura,

        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

        Here it is. The new UltiMaker S7

        MariMakes posted a topic in Official news,

        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 🎄

        Cura Alpha With New Tree Support 🎄

        MariMakes posted a topic in Ultimaker Cura,

        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.
