Cura-IE-4.1-Beta3 - Release Notes

❓This beta release is ready for printing. As of Aug 27, 2019, it has been in private beta testing for three weeks.
Yet, it has not been out in the real world, and there may be issues lurking in the shadows.

Known Issues

SD Card Boot Loop. Some people experience SD card issues if they use the 'save to SD' button from withing Cura. When the SD card would be inserted in the LCD SD card reader, the JellyBOX would get stuck in a boot loop and never start (only as long as the SD is inserted)! We're investigating this bug.

• Easy Workaround: Save the gcode to the disc first, and then copy it to the SD card. This works fine!
  • Fix if this happens: Format the SD card (howto guide for PC, howto guide for Mac))) and all will be fine.
    • Format as FAT32 or ExFat. Details in the guides linked above.

User Relevant Changes Compared with Cura IE 3.5.x

_(Info below build upon and adapted from the Ultimaker Cura changelog. Go check it out if you want to see bug fixes and developer related info.

🎁 New! Updated user interface

Cura is a very powerful tool with many features to support users’ needs. In the new UI, we present these features in a better, more intuitive way based on the workflow of our users. Three stages are shown in the header to give a clear guidance of the flow. The stage menu is populated with collapsible panels that allow users to focus on the 3D view when needed, while still showing important information at the same time, such as slicing configuration and settings. Users can now easily go to the preview stage to examine the layer view after slicing the model, which previously was less obvious or hidden. The new UI also creates more distinction between recommended and custom mode. Novice users or users who are not interested in all the settings can easily prepare a file, relying on the strength of expert-configured print profiles. Experienced users who want greater control can configure over 300 settings.

🎁 New! Draggable settings panels

The print settings panel (prepare stage) and the color scheme panel (preview stage) can be dragged and positioned anywhere in the 3D viewer. A double click of the header will reset each to their default position.

🎁 New! Gyroid infill

New infill pattern with enhanced strength properties. Gyroid infill is one of the strongest infill types for a given weight, has isotropic properties, and prints relatively fast with reduced material use and a fully connected part interior. Note: Slicing time can increase up to 40 seconds or more, depending on the model. Contributed by smartavionics.

🎁 New! Gyroid support

Smartavionics has contributed a new option for a gyroid support pattern, similar to his gyroid infill contribution. A gyroid pattern is relatively efficient with material, so gyroid patterns permeable to water can dissolve faster. It’s also easier to pull gyroid structures off your model with pliers compared to some other support patterns.

🎁 New! Parametrize the Start Gcode to accomodate FLEX materials

🏷️ JellyBOX-specific: Nothing in the start or end gcode is hardcoded anymore. This is a big deal. Previously, all JellyBOXes preheated to the same temperatures and printed the same purging/cleaning line at the same speed. This did NOT work well for flexibles for example - they just cannot print as fast as PLA. Now, the start gcode is parametrized with custom parameters, so that it can work for all materials and profiles!

🎁 New! Fullscreen mode shortcuts

Fullscreen mode can be toggled using the View menu or with the keyboard shortcuts: Command + Control + F (macOS), or F11 (Windows and Linux). Contributed by KangDroid.

👍 Improved! Keyboard shortcuts

The keyboard shortcuts, which used to be undocumented, are now both documented and more logical.

• T to Transform
  • (previously q)
• S to Scale
  • (previously a)
• R to Rotate
  • (previously z)
• M to Mirror/flip
  • (previously w)

👍 Improved! UI speed

This version switches faster between extruders and printers. Your mileage may vary depending on your system specifications.

👍 Improved! Lazy Tree Support calculation

In previous versions, 95% of Tree Support’s computation time was used to calculate the collision volumes to make sure that the branches avoid collisions with the meshes. Now it calculates these volumes only when necessary, reducing the computation time. Contributed by bjude.

👍 Improved! Support brim

New setting that integrates the first layer of support material with the brim’s geometry. This significantly improves adhesion when printing with support material. Contributed by BagelOrb.

👍 Improved! Expert settings visibility

Previously, new settings weren't displayed in the expert preset even though they were expert-level settings. The latest features (e.g. Prime tower brim) are now included in the expert preset, for easy access.

👍 Improved! Increased rendering speed

Rendering speed improvements that should be quite noticeable with multiple objects on the build plate.

🎁 New! Layer change script

This new post-processing script injects custom Gcode on a layer change, so that manual commands can be defined, e.g. park the print head. Contributed by wporter82.

👍 Improved! Mac installation process

The app now should be installable by non-admins on Mac without issue. The app and the archive are now both digitally signed with imade3d credentials.
