Cura Team, as part of and with help from Ultimaker R&D in a more general sense, have been working on a large project that changes the core of how our slicing engine works.
The goal is to have variable line widths (instead of static) for each extrusion, and better path-planning, in order to better fit the eventual printed part to the specifications.
-If after you've used this alpha you want to give some feedback (please do, it's the main reason we're doing this), please see <a href="https://github.com/Ultimaker/Cura/discussions/8965">the discussion here</a>.

+<br>Not everything has been implemented, and there are even an amount of known bugs (see below), as well as very probably a comparable amount of unknown issues.
On top of that, we added some parameters (and removed a few others). These have hardly been tuned, even for our own printers, let alone 3rd party ones.
In other words, don't expect perfection. In fact, the default settings as they are now are likely to be worse as what's there in a lot of cases.
-Note: This is _not_ otherwise build on a specific version (like '4.8.0' or similar), so there may be issues that have been solved or introduced since then that have little or nothing to do with the Variable Line Width feature-set!

* New Settings
Variable Line Strategy: How the walls are spread over the available space.
-- Central Deviation: Will print all walls at the nominal line width except the central one(s), causing big variations in the center but very consistent outsides.
-- Distributed: Distributes the width variations equally over all walls.
-- Inward Distributed: Is a balance between the other two, distributing the changes in width over all walls but keeping the walls on the outside slightly more consistent.
-Minimum Variable Line Width: The smallest line width, as a factor of the normal line width, beyond which it will choose to use fewer, but wider lines to fill the available space. Reduce this threshold to use more, thinner lines. Increase to use fewer, wider lines.
-Wall Transition Length: When transitioning between different numbers of walls as the part becomes thinner, a certain amount of space is allotted to split or join the wall lines.
-Wall Transition Angle: When transitioning between different numbers of walls as the part becomes thinner, two adjacent walls will join together at this angle. This can make the walls come together faster than what the Wall Transition Length indicates, filling the space better.
-Wall Transition Filter Distance: If it would be transitioning back and forth between different numbers of walls in quick succession, don't transition at all. Remove transitions if they are closer together than this distance.
