                  Extruders

                  In this section, it is possible to choose which extruder in your printer to print specific parts.

                  Perimeter extruder

                  Extruder to use when printing perimeters and brim.

                  Infill extruder

                  The extruder to use when printing infill.

                  Solid infill extruder

                  The extruder to use when printing solid infill.

                  Support material/raft/skirt extruder

                  The extruder to use when printing support material, raft and skirt. Set to 0 to use the current extruder, which will minimize tool changes.

                  Support material/raft interface extruder

                  The extruder to use when printing support material interface. Set to 0 to use the current extruder, which will minimize tool changes. This also affects the raft.

                  Wipe tower extruder

                  The extruder to use when printing the perimeter of the wipe tower. Set to 0 to use the current extruder. The current extruder is preferred when using soluble supports.

                  Bed temperature by extruder

                  This is the extruder that determines the heatbed temperature. Set to 0 to determine the temperature based on the first printing extruder of the first and second layers.

                  Ooze prevention

                  Enabling Ooze prevention drops the temperature of the inactive extruders to prevent oozing.

                  Temperature variation

                  Temperature difference to be applied when an extruder is not active. The value is not used when "Idle temperature" in filament settings is defined.

                  Wipe tower

                  Read more about the wipe tower settings here: Stringing and oozing.

                  Advanced

                  The features here help to create a strong well-bonded multi-material print by improving their strength and reliability.

                  Interface shells

                  Force the generation of solid shells between adjacent materials/volumes. This is seful for multi-extruder prints with translucent materials or manual soluble support material.

                  Maximum width of a segmented region

                  Maximum width of a segmented region. Zero disables this feature.

                  This feature cannot be used when "Use beam interlocking" is selected.

                  Interlocking depth of a segmented region

                  Maximum depth of a segmented region. This feature is disabled if the value is zero, if the "Maximum width of a segmented region" is zero, or if a value higher than "Maximum width of a segmented region" is used.

                  This setting improves adhesion between painted color/material patches and helps prevent separation between colors. This is especially useful for models painted or merged in the slicer rather than split into separate physical meshes

                  This feature cannot be used when "Use beam interlocking" is selected.

                  Use beam interlocking

                  This feature is based on the implementation of OrcaSlicer.

                  Enable this feature to create internal cross-hatched beams at material boundaries to strengthen their bond. It works for face-to-face touching volumes, overlapping volumes, and painted regions with assigned materials. It is also useful when mixing materials and when printing structural parts with embedded flexible or soft sections.

                  This feature is disabled by default.

                  Interlocking beam width

                  The width of the interlocking structure beams.

                  Interlocking directions

                  Orientation of interlocking beams.

                  Interlocking beam layers

                  The height of the beams of the interlocking structure, measured in number of layers. Using fewer layers will make the connection stronger but more prone to defect.

                  Interlocking depth

                  The distance from the boundary between filaments to generate the interlocking structure, measured in cells. Too few cells will result in poor adhesion.

                  Interlocking boundary avoidance

                  The distance from the outside of a model where interlocking structures will not be generated, measured in cells.

                  Perimter Extruder setting is ignored when enabling a brim in a multitool setup with mixed materials for part and support.

                  Interlocking beam details could use a little more love -- units are not clear for beam width, depth, and boundary avoidance. What are "cells"?

                  I agree; I think I found the answer in AI: it says that the interface shells make denser layers surrounding the part. For example, the part might be surrounded with lower layer heights, more perimeters, and other things for better adhesion of the part.
