UltiMaker Cura 5.2.0

Abstract Cloud Printer Type Online cloud printers are now grouped by type. You can slice with the ('abstract') printer type, and afterwards choose a specific printer to print with.

Support For 'Guest'-Type Accounts (In Digital Factory) Users with the ‘Guest’ role can prepare print jobs in Ultimaker Cura and send them to the printers via Digital Factory. These print jobs will not start until they are approved by a user with an 'Member' or 'Admin' role.

More Control Over Initial Layer Flow Three new settings: 'Initial Layer Outer Wall Flow', 'Initial Layer Inner Wall Flow', 'Initial Layer Bottom Flow', to better counteract the 'elephants foot' phenomenon.

Other new features and improvements:

• Auto-remove holes from not completely solid models in vase-mode
• Add setting for 'tree support max diameter'
• Add option to drop-down models to the build-plate individually, contributed by @Piezoid
• Added a preference to make the tray icon optional, contributed by @fieldOfView
• (Community Developer Update: Proper workflow for 'installing from source' on Windows! See our wiki.)

Known critical issues:

• While some small fixes have been made already, the placement of the seam is still more scattered than before 5.0. (Will try to fix in stable.)
• Support is sometimes missing in detailed parts, where previous releases supported them properly (still). (Will probably not be fixed in stable. This is currently slated for 5.3)
• Multiple external monitors on Windows (especially if from the same brand) might be a problem under some circumstances. (Will probably not be fixed in stable.)
