Ultimaker Cura 5.3.0

What's new in this version:

Interlocking Structure Generation:
- This new setting enables you to interlock multiple materials together, even if those materials are not compatible

Brim per Material:
- A brim can now be printed with multiple materials in the same model

Updated Recommended Print Settings Menu:
- The number of settings available in the recommended has expanded. The redesign will make it easier to use intent profiles or save custom profiles.

- Added settings for Support Interface Wall Line Count, Support Roof Line Count, and Support Floor Line Count
- Added Brim Inside Avoid Margin setting
- Added prefix 'Printing' to post processing plugin script "DisplayFilenameAndLayerOnLCD
- Added Enable, G-code Before, and G-code After To Filament Change

- Added an option to keep stepper motors engaged to Pause At Height
- Added an option to Beep at Pause to Pause At Height
- Added Additional Gcode Fields to Pause At Height
- Make Layer Number the default in Pause At Height
- Added more information when rotating a model using the arrows
- Added the "CTRL +" shortcut to open Preferences window
- Added the option to add Machine Action buttons in the Printer Preferences

Fixed:
- a slicing crash if models were placed in the center of the buildplate
- a slicing crash that would happen if Adaptive Layers Maximum Variation had a negative value
- a bug where an "object of type SettingFunction is not JSON serializable" error would prevent users from using certain plug-ins
- a bug where hole expansion would affect interlocking holes
- a bug where fuzzy skin would also apply to interlocking structures
- a bug where you could not load gcodes in Cura in some cases
- a bug where some models would slice slower with Skin-Edge Support Layers
- a bug where layers were skipped by inserting a support interface on a raft
- a bug where Relative Extrusion was not calculated correctly when using Retract Continue
- a bug that would prevent advanced users from slicing a batch with multiple STLs in a script
- a bug where skirt lines would not follow the convex contours of models
- a bug where Exclusing Slicing Tolerance was not applied correctly to bottom-layer(s)
- a bug where small travels were not retracted correctly
- a bug where the printjob time showed 0 minutes if adaptive layer height was enabled
- a bug with Skin Overlap where the skin would overlap with the roofing
- a bug where Support Interface would be generated on top of support
- a bug where the Floor Support Interface would not be generated in certain models
- a bug where a long material list would disappear from the screen
- a bug where support is not generated correctly if Support Pattern is Concentric
- a bug where an increased Skin Removal Width would cut off part of the skin area
- a bug where Support Towers would be generated but would support nothing
- a bug where Small Feature Size would also be applied to inner-wall loops
- a bug where adhesion would be printed outside of the buildplate
- a bug where a primetower brim was printed when it shouldn't
- a bug where Ooze/Draft shields did not avoid prime tower
- a bug where not all Mac users could not use USB printing
- input value for platform offset when adding a logo
- a bug where the travel move at the end of a layer unretracts
- a bug where WallToolPaths are not simplified
- a bug where iterators were moving out of range
- a bug where the Maximum Area Deviation value was too small
- a bug where we did not 'pickle' DefinitionContainers correctly
- a bug where an airgap was present in Spiralized Outer Contour
- a bug where speeds defined for slower layers would impact speeds accelerations and jerks for the whole print
- a bug where materials with longer names in Materials Preferences were harder to read
