3DBenchy Slicing Failure when disabling "Use Adaptive Layers" while tweaking print settings.

Cura Version

5.9.0

Operating System

Windows 10 Pro, RX 6800

Printer

Sovol SV06

Name abnormal settings

Turning off "Use Adaptive Layers" causes slicing failure. Re-enabling it reverses the problem.

Describe model location

Model is centered on build plate. Rotating 90 deg worked once, repeated attempts to slice continued to fail.

Describe your model

3DBenchy. This is the first time I have encountered the error with the model, have printed successfully before. It is not watertight. Mesh Fix did not correct the problem.

This occurred during a long session (1-2hrs) of slicing, printing, tweaking settings, and re-slicing within the same instance of Cura.

Thanks for the report.
The model error doesn't appear to be a problem. I repaired the model with MS 3D Builder and the slice failed.
I can duplicate the failure in 5.9.0 but it doesn't happen in 5.8.0.
It's odd that it happens with Adaptive Layers turned off. You would think it would happen the other way.
If I turn on Adaptive Layers and then toggle the "Adaptive Layer Variation Step Size" to 0.02 and then back to 0.04 then turn Adaptive Layers off again - the problem goes away. Maybe it's using the hidden value when it should not. That has happened with other settings.

The Cura team will take a look.

Looking at your settings - your Initial Layer Line Width is 150% and your "Initial Layer Flow" is 120%. That's pushing a lot of plastic and will have secondary effects. A 0.30 nozzle won't be happy having to deliver a line width of 0.54.

Thank you for your advice on the initial layer settings, I will tune that down!
