UltiMaker Cura 5.6.0

New features and improvements

Introduced the MethodX and MethodXL printers with it's materials and the option to write to .makerbot
A year after the merger of Ultimaker and MakerBot, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method X and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse

Prime tower base settings increase the stability of large prime towers
New settings have been released that let you modify the base of your prime tower. The new settings are:

• Prime Tower Base Size
• Prime Tower Base Height
• Prime Tower Base Slope
• Prime Tower Raft Line Spacing

You can modify these settings to help improve the reliability of your prime towers. You can also use them to calibrate how well your prime tower adheres to the build plate for increased print success, or to avoid over-adhesion that may damage your build plate.

The Start and End gcodes now accept variables and math including the variables
Cura can now accept more start and end gcodes that include math, for example:

G0 X{prime_tower_position_x - prime_tower_size/2} Y{prime_tower_position_y-prime_tower_size/2} F6000
M109 S{material_final_print_temperature}

This hopefully also solves issues like #14111 (comment) and #16012 (comment)

Other Improvements

• Introduced the setting for Raft Line Spacing, but for the prime tower
• Updated the Support Z Distance to allow for more different values, no longer only multiple layerheights, solves #6105

Bug Fixes

• Fixed a crash for some Linux users when trying to open the file menu

Bugs resolved since the Beta Release

• Introduced Balanced and Solid profiles for 1C extruders to UltiMaker Method X and Method XL
• Improved self-support for UltiMaker MethodX and MethodXL printers so the support extruder will not be used
• The prime tower is now always enabled when the second extruder is used for the MethodX and MethodXL printers
• Updated the default prime tower position so it doesn't prevent slicing for some printers
• Fixed an issue where raft layers were partially printed
• Slice information template variables were not available through start-end code formulas
• Resolved an issue with 100% support roof for tree support, contributed by @ThomasRahm

Printer Definitions, and Community Translations

• Introduced Ender 3 V3 SE, contributed by @dim1triy
• Updated bridge flows for UltiMaker PLA, TPLA and ABS to address pillowing in AA 0.8 for UltiMaker printers
• Updated Spanish translation for Lightning infill, contributed by @Pelochus
• Updated German translation for Laying object flat on buildplate, contributed by @gluetolf
• Updated Brazilian translations, contributed by @Patola

Known Issues

• The predicted printing time for dual extrusion printjobs on the Method series are deviating from the actual printing time.
• It’s not possible yet, to use Method series printers with Digital Factory. We hope to resolve this for the next release.

New Engine Plugin

Not related to this release but nice to mention is that there is a new plugin has been created by the Cura team that makes use of the improved engine plugin capabilities introduced in Cura 5.5 (as mentioned #15629). The plugin is called CuraEngine Tiled Infill Generation and it allows users to select from an expanded list of infill patterns, as well as allowing users to add their own infill pattern by uploading a *.wtk file.

This plugin is just a taste of what is now possible when creating Cura plugins. We look forward to seeing what the Cura community creates next!

UltiMaker Cura 5.5.0

New features and improvements

Engine Plugins
Introduced infrastructure for Engine Plugins; Plugin developers can now hook into and change the actual slice process using a programming language in which they feel comfortable: C++, Python, C#/.NET, Dart, Go, Java, Kotlin, Node, Objective-C, PHP, Ruby
In this initial version, plugins can hook into the following engine slots:

• Modify generated gcode, postprocessing it per layer
• Generate Infill patterns
• Modify extrusion paths
• Listen to a broadcast of all Settings

Cura plugins can now easily add new Settings and extend existing dropdown Settings. Users are now warned if a previously saved project file depends on a plugin and that plugin isn't installed in the Cura instance that tries to load it.

To showcase this new infrastructure we introduced a Gradual Flow Engine plugin; This plugin prevents sudden drastic changes in flow transitions. You can find it under your bundled plugins and the new gradual flow settings can be found in the material category when all settings are visible
Do you want to participate in the discussion about the potential and possibilities? You can join the discussion on GitHub here.

Introduced the following new settings
Gradual Flow Enabled, Gradual Flow Max Acceleration, Initial Layer Max Flow Acceleration, Gradual Flow discretization step size, are to finetune the Gradual Flow plug-in.

Top Surface Outer Wall Flow, Top Surface Inner Wall Flow, Top Surface Outer Wall Speed, Top Surface Inner Wall Speed, Top Surface Outer Wall Acceleration, Top Surface Inner Wall Acceleration, Top Surface Outer Wall Jerk, and Top Surface Inner Wall Jerk settings can be used to tune the top surface of your models.

Small Top/Bottom Width reduces jerky motions in small top/bottom surfaces, with Small Top/Bottom On Surface you can exclude the setting on the surface

Group Outer Walls will bundle types of walls in the same layer reducing travels, thanks to the contribution by @Arcari55

Enable Fluid Motion, Fluid Motion Shift Distance, Fluid Motions Small Distance, and Fluid Motion Angle are settings for printers with smooth motion planners like Klipper. It's hard to show the changes in preview, but we encourage you to check it out.

Updates in the available supported OSses

• Introduced Max OSX builds for ARM64 (M1 support), next to our existing X64 builds. With major contributions from @TheSin
• Introduced a single Linux build removing the need to have a different modern and regular Linux build.

Setting improvements for Ultimaker Printers

• UltiMaker printers with UltiMaker Materials have faster-predicted printing times as a result of a number of changed printing speeds
• UltiMaker configurations with limited intents in the past like AA 0.8 cores, now have more intents available
• Updated printing temperatures for UltiMaker printers to be more uniform
• Updated Support Interface Settings for UltiMaker printers
• Introduced a support material tag, so support is automatically printed with support material
• Default has been updated to Balanced to reflect the perfect harmony between these visual, engineering, and draft profiles.

Quality of Life Improvements

• It seemed like models could be multiplied more than 99 times, there is now a limit, solves #14105
• It's now more clear if Cura is syncing materials over the cloud
• It's not possible anymore to send a printjob to a turned off cloud connected UltiMaker printer

More Features

• You can now sponsor the Cura team from the Application Switcher, and Help menu
• Infill behavior close to the skin to prevent jerky motions and visible overextrusion
• The About Dialog includes more build information for Cura developers
• Introduced more hardware info like system, release, version, processor, and CPU cores to the logging to improve troubleshooting.

• Combing Not In Skin can result in unexpected stringing. We are tracking reports here.
• Multiple external monitors on Windows (especially if from the same brand) might be a problem under some circumstances.
• Does Cura (not) work on your OS (version)? See this article for clarification.

We are interested in having Cura and Klipper/Smooth Motion 3D printers work together more smoothly and are looking for input on how to do this. Do you have feedback on this topic? Please leave a comment on our discussion.

Known critical issues:

• 🌍 Currently the translation files seem to be missing in these Beta builds. We are working on a solution so everyone can test this Beta in their preferred language. Translations are now available!
• Under certain angles, the Interlocking Structures are not effective, yet.
• The Gcode Reader Plug-in is broken since Cura 5.2, and will not load gcodes correctly yet.
• Some models have been slicing slower since Cura 5.1. #14108
• Reports have been coming in that Cura is running slow on Windows 11 #13820
• Multiple external monitors on Windows (especially if from the same brand) <a href="https://support.ultimaker.com/hc/en-us...
