This is a hotfix version based on V220.127.116.11
Starting from version 1.7.1, the default wall generator has been switched to Arachne with variable line width.
Arachne, compared to the classic wall generator, is more complex. Many users have reported a significant increase in processing time at 15% slicing stage when slicing complex models.
Therefore, we have prioritized optimizing the slicing speed when both the Arachne and overhang slowdown features are enabled.
Below, you can see a 3mf test and the slicing time comparison:
However, if the model is extremely complex (for instance, when slicing a lithophane.) and continues to be sliced slowly in the hotfix version, we recommend switching to the classic wall generator or disabling the overhang slowdown feature as a workaround.
Please refer to the following example below:
Performance issues are not always quick to resolve, but we will continue to optimize, as always.
Please don't hesitate to report any issues you encounter.
We greatly appreciate all constructive feedback and suggestions from our users!
One wall on the top surface option is important to improve the top surface quality.
After switching the default wall generator to Arachne from V1.7.0 public beta, users reported that the top surface is bad, because Arachne couldn't be used with one wall on the top surface together at the same time.
We have tested this option before and found that this was causing the slicing process to be too slow. However, we found a solution and this option is now available in release.
You can now use the Arachne wall generator with “one wall on top surface” option for both “all top surfaces” and “only topmost surface”. The “only topmost surface” option can only make the topmost layer be one wall, but it can slice much faster than “all top surfaces” when model is very complex.
Please check the comparison below for details.
