Hi everyone,

 

Earlier this year, we released the first beta of Ultimaker Cura Arachne engine. Which received an overwhelmingly positive response, thank you for all your feedback!

Since the first beta release we've been working on improving the Arachne engine.

 

What is the Arachne Engine?

Our new Ultimaker Cura engine allows you to create parts with ground-breaking quality, strength, and speed. This is made possible by fundamentally redefining how the inside of a model is generated – through adaptive line widths and optimized line positioning.

New features in Arachne second beta:

Back pressure compensation

Print quality is improved through dynamically adjusting print head velocity, which slows down or speeds up depending on the pressure of the material through the Bowden tube.

Printing order filling gaps

Gaps in models are now filled in after placing the outer wall, resulting in less over-extrusion.

Print quality enhancements

All print quality improvements from Ultimaker Cura 4.12 have been added.

 

Bug fixes:

- Fixed a bug where blobs in g-code were generated

- Fixed a bug where the Inner Line Width was wider than the end of the model

- Fixed a bug where the Seam placement was not on the correct corner

 

Read the full release notes for all the bug fixes and the known issues or read our full blog post.

Is this new engine (when finally released) going to allow prints that have text in the first layer, to be printed with a brim on the OUTSIDE of the model only? So text doesn't get filled in?

    Hi:  This seems really great!  However, no Outer Before Inner Walls option?  My parts aren't printing well with what seems to be the default or hard-coded inner before outer.

     

    Thanks.

    Would it be possible to slice in the way shown in the picture?

     

    At  the moment i adjust the code manually. Is there a way to make it with Cura software?

    The print is much stronger this way.

    @surfski - I think it's now under Wall Ordering and the selection would be Outside to Inside

    @JackW327 Thank you!  I searched and searched for that setting, and couldn't find it.  Finally realized I had to "manage setting visibility" and enable it (along with many many other features!).   Strange to me that new and/or Arachne-specific features would be disabled by default...

    Did you know there's a helpful search field atop of the settings that helps you search for settings? It also shows settings that have not yet been made visible.

     

    The whole idea of NOT making all of the >300 settings visible is to make it easier to find the often-used important settings. Need something advanced? Use the search feature. Turns out you need that advanced feature often? Make it visible. Personally I like staying on the "Basic" set of visible settings, and use the search for the rest.

    Been using it for a few weeks now - significant improvement in stability from Beta 1.
    - Occasional crashes but have not been able to reproduce (may be graphics card related)
    - Generally it "feels" faster (have not done back-to-back tests)

    @ahoeben  Thank you - I agree that search can be helpful.  However, if you don't know the name of a feature, it's quite difficult.  In regular Cura it's "outer before inner walls."  In S3D the it's "outline direction".  In PrusaSlicer it's "external perimeters first."  (And very easy to find.)  Searching with most of those keywords doesn't bring up "wall ordering."  If you know that the feature name has the word "wall," you will find it buried amongst ~80 other features.  So for me, search wasn't helpful in this case.  Second, this feature isn't advanced, but one of the most basic or fundamental.  It often makes the difference between a print completing, or utterly failing.

    @samhar, how about versions 4.11, 4.12 & 4.13? They don't have the Arachne engine.
